Mr. Dykann: This letter is to inform you that the above-referenced, OWTS-3-18-18746 permit, has been inspected and finalized. This OWTS permit was approved and sized to serve a five (5) bedroom residence. Additional information about the maintenance your septic system needs can be accessed through our website links, provided on the Environmental Health Department’s septic system resource page. Be aware that changes in the use of your property or alterations of your building may require commensurate changes to, or relocation of, your septic system . Landscape features, trees with tap roots, irrigation systems and parking areas above the soil treatment area can cause premature system failure. It is equally important that you notice and immediately repair dripping faucets and hissing toilets as this will certainly cause the system to fail. If you have any questions regarding this information, please contact us at (970) 328-8755 and reference the OWTS septic permit number. Best Regards, Giovanna Harkay.

Avalanche Excavation installed the new septic tank. After determining the soil treatment area (STA) was not functioning, an amended permit was issued for replacement of the STA. Installation observations were made on November 5, 2018 and May 29, 2019. Altitude Septic installed the new pump tank and STA. The existing metal septic tank was pumped and removed. The existing STA was abandoned in place. Attempts were made to locate the water line; however, they were unsuccessful. The approximate location of the water line was described by you, the property owner. The pump line was encased approximately 20-feet on each side of the described water line location. The ditch was placed in a culvert within 50-feet of the new STA. The system installation included a new 1500-gallon, two-compartment Roth poly septic tank (Avalanche Excavation) with an effluent filter in on the outlet tee. This filter must be cleaned annually, or as needed. Additional system components were installed by Altitude Septic, including a 500-gallon, poly Infiltrator® pump chamber with an Orenco® Biotube Pump Vault and an Orenco® PF3005 pump. The filter in the pump chamber must also be cleaned annually, or as needed. The floats were set to dose approximately 80 gallons each pump cycle, allowing for approximately 10 gallons of drain back after each pump cycle. The control panel for the pump is located on the north side of the residence, within line of sight of the septic tank. Valley Precast out of Buena Vista performed start-up of the pumping system. Effluent is pressure dosed through a 1.5-inch diameter pump line to an Orenco® automatic distributing valve (ADV), model 6402. The ADV was placed at the high point in the system in an insulated riser with access from grade. Effluent is pressure dosed to two over-excavated, 12’ x 31.5’ unlined sand filters with 3-feet of sand filter material (Secondary Sand). Pipes used to disperse the effluent were surrounded by washed coarse screened gravel. Manifolds were 1.5-inches in diameter. Laterals were 1.5-inches in diameter with 5/32- inch diameter orifice holes facing down, spaced 2-feet on center. Laterals start 2-feet from the sidewall of the sand filter and the middle laterals were separated by 4-feet. Each 1.5-inch diameter lateral ends in a sweeping ell facing up with a ball valve for flushing. A soil separation fabric was placed over the gravel layer followed by approximately 1-foot of topsoil. The OWTS was generally installed according to specifications. This observation is not a guarantee of workmanship and/or parts and materials. ALL SERVICE septic, LLC should be notified if changes are made to the OW TS in the future. Any additional OWTS construction must be according to the county regulations. LIMITS: Observations are limited to components that are visible at the time of the inspection . The installer must have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. The quality of the installation is dependent of the expertise of the installer, soil type, and weather conditions. Please call with questions.

The 2.43-acre property is located outside of Basalt, in an area where Onsite Wastewater Treatment Systems (OW TS)s and wells are necessary. The legal description of the property is Lot 3, Willoughby, Thomas, and Phillips Subdivision. Parcel ID: 2465-123-03-003 SITE CONDITIONS A 5-bedroom, single-family residence presently exists on the property and is utilizing an existing OWTS. Eagle County Environmental Health Department was unable to locate documents pertaining to the existing OWTS, likely due to age of the system. The existing metal septic tank is showing signs of deterioration and there is a desire to replace the septic tank. The residence is served potable water by a private well, located on to the northwest of the exiting residence, near Sopris Creek. The water line enters the property from the west and loops around the existing STA, coming into the north side of the residence. This water line will be at least 25-feet from the new septic tank. DESIGN SPECIFICATIONS The existing septic tank must be pumped and removed. A new, 4-inch diameter SDR-35 sewer line with a double-sweep clean out will be run from the house to a new, 1500-gallon, two-compartment Roth® poly, two-compartment septic tank. An Orenco® Biotube Jr. Effluent Filter must be installed on the outlet tee of the septic tank. This filter must be cleaned annually, or as needed. Both manhole lids must be brought to grade with risers for access. If the existing sewer line from the septic tank to the existing soil treatment area (STA) is cast iron, or found to be in poor condition, we recommend replacement with 4-inch SDR-35 sewer pipe. At the time of the tank installation, at least 100-gallons of water should be run into the existing STA to assure it is accepting effluent. Page 2 The component manufacturers are typical of applications used by contractors and engineers in this area. Alternatives may be considered or recommended by contacting our office. Construction must be according to Eagle County On-Site Wastewater Treatment System Regulations, the OWTS Permit provided by Eagle County Environmental Health Department, and this design. OPERATION INFORMATION AND MAINTENANCE The property owner shall be responsible for the operation and maintenance of each OWTS servicing the property. The property owner is responsible for maintaining service contracts for manufactured units, alternating STAs, and any other components needing maintenance. Geo-fabrics or plastics should not be used over the STA. No heavy equipment, machinery, or materials should be placed on the backfilled STA. Livestock should not graze on the STA. Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWTS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a STA. If an effluent filter or screen has been installed in the OWTS, we recommend this filter or screen be cleaned annually, or as needed. The homeowner should pump the septic tank every two years, or as needed gauged by measurement of solids in the tank. Garbage disposal use should be minimized, and non-biodegradable materials should not be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste only. ADDITIONAL CONSTRUCTION NOTES Excavation equipment must not drive in excavation of the STA due to the potential to compact soil. Extensions should be placed on all septic tank components to allow access to them from existing grade. Backfill over the STA must be uniform and granular with no material greater than minus 3-inch. INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC must view the OWTS during construction. The OWTS observation should be performed before backfill, after placement of OWTS components. Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. ALL SERVICE septic, LLC should be notified 48 hours in advance to observe the installation. Page 3 LIMITS: The design is based on information submitted.

The 2.43-acre property is located outside of Basalt, in an area where OW TSs and wells are necessary. The legal description of the property is Lot 3, Willoughby, Thomas, and Phillips Subdivision. Parcel ID: 2465-123-03-003 SITE CONDITIONS A 5-bedroom, single-family residence presently exists on the property and is utilizing an existing OWTS. Eagle County Environmental Health Department was unable to locate documents pertaining to the existing OWTS, likely due to age of the system. The existing metal septic tank was recently replaced under Permit No. OWTS-3-18-18746. The existing soil treatment area (STA) was tested by running approximately 100 gallons of water into the STA and it was no longer accepting water or effluent. The residence is served potable water by a private well, located on to the northwest of the existing residence, near Sopris Creek. The water line enters the property from the west and loops around the existing STA, coming into the north side of the residence. This water line will be at least 25-feet from the new septic tank and STA. The new sewer line from the pump chamber will likely cross the existing water line. The sewer line must be properly encased 5-feet of each side of the crossing (see Detail 3/ w4.0). Several ditches and a pond are present on the property and minimize the property available for replacement of the STA. There must be at least 50-feet from any ditch or pond on the property. If the 50-foot setback cannot be met to the ditch(es), they must be placed in a culvert or lined with minimum 30 mil liner. Table 1 describes the minimum required setback of OWTS components to physical features on the property compared to approximate, proposed setback distances.

A visual and tactile soil analysis was completed by Carla Ostberg at the time of excavation.1 The materials encountered in the Test Pit #1 consisted of gray topsoil (which may have been imported), underlain by medium brown loamy sand with more than 35% rock to a maximum depth explored of 6.5- feet. No bedrock or groundwater was encountered. The materials encountered in Test Pit #2 consisted of medium brown sandy loam to 2.5-feet, underlain by light brown loamy sand with greater than 35% to a maximum depth explored of 6.5-feet. No bedrock or groundwater was encountered. Soils below the topsoil horizon are Soil Type 0 due to rock content. An over-excavated, unlined sand filter is proposed. Locally available sand is Secondary Sand. A long term acceptance rate (LTAR) of 0.8 gallons per square foot, will be used to design the OWTS, in accordance Eagle County On-Site Wastewater Treatment System Regulations. Approximate area of proposed STAs 1 Carla Ostberg holds a Certificate of Attendance and Examination from the CPOW Visual and Tactile Evaluation of Soils Training.

Design Calculations: 3 bedrooms x 75 GPD x 2 people/bedroom + 150 GPD (4th and 5th bedrooms) = 600 GPD STA Calculations = 600 GPD / 0.8 gallons/SF (Secondary Sand) = 750 SF (2) 12’ x 31.5’ over-excavated, unlined sand filters (min. 3’ sand filter material) A new, Roth® 1500-gallon, two-compartment poly septic tank was installed under Permit No. OWTS-3- 18-18746. An additional 500-gallon pump chamber with an Orenco® Biotube Pump Vault and an Orenco® PF3005 pump must be installed after the existing septic tank. We have provided specifications for an Infiltrator® septic tank; however, a Roth® tank may be used along with the necessary adapter to house the Orenco® Pump Vault. The floats should be set to dose approximately 80 gallons each pump cycle, allowing for approximately 10 gallons of drain back after each pump cycle. The control panel for the pump must be located within line of sight of the septic tank. We recommend Valley Precast out of Buena Vista be contracted for start-up of the pumping system. Effluent will be pressure dosed through a 1.5-inch diameter pump line to an Orenco® automatic distributing valve (ADV), model 6402. This pump line must have a minimum 1% grade for proper drain back into the tank after each pump cycle. The ADV must be placed a high point in the system and be placed in an insulated riser with access from grade. Screened rock must be placed below the ADV to support the ADV and to assure the clear pipes existing the ADV remain visible for future inspection and maintenance. Page 5 Effluent will be dosed to two over-excavated, 12’ x 31.5’ unlined sand filters with a minimum of 3-feet of sand filter material (Secondary Sand). Sand filter material must be clean, coarse sand, all passing a screen having four meshes to the inch. The sand must have an effective size between 0.15 and 0.60 mm. The uniformity coefficient must be 7.0 or less. Material meeting ASTM 33, for concrete sand, with three percent or less fines passing 200 mesh sieve may be used. A gradation of the sand media must be provided. The gradation must be dated no more than one month prior to the installation date. Pipes used to disperse the effluent must be surrounded by washed coarse screened gravel or crushed stone. All of the gravel or stone must pass a 2 ½-inch screen and must be retained on a ¾-inch screen. The manifold must be 1.5-inches in diameter. Laterals must be 1.5-inches in diameter with 5/32-inch diameter orifice holes facing down, spaced 2-feet on center. Laterals must start 2-feet from the sidewall of the sand filter and the middle laterals will be separated by 4-feet. Each 1.5-inch diameter lateral must end in a sweeping ell facing up with a ball valve for flushing. A soil separation fabric should be placed over the gravel layer followed by approximately 1-foot of topsoil or other suitable soil able to support vegetative growth. The component manufacturers are typical of applications used by contractors and engineers in this area. Alternatives may be considered or recommended by contacting our office. Construction must be according to Eagle County On-Site Wastewater Treatment System Regulations, the OWTS Permit provided by Eagle County Environmental Health Department, and this design. REVEGETATION REQUIREMENTS An adequate layer of good quality topsoil capable of supporting revegetation shall be placed over the entire disturbed area of the OWTS installation. A mixture of native grass seed that has good soil stabilizing characteristics (but without taproots), provides a maximum transpiration rate, and competes well with successional species. No trees or shrubs, or any vegetation requiring regular irritation shall be placed over the area. Until vegetation is reestablished, erosion and sediment control measures shall be implemented and maintained on site. The owner of the OWTS shall be responsible for maintaining proper vegetation cover. OPERATION INFORMATION AND MAINTENANCE The property owner shall be responsible for the operation and maintenance of each OWTS servicing the property. The property owner is responsible for maintaining service contracts for manufactured units, alternating STAs, and any other components needing maintenance. Geo-fabrics or plastics should not be used over the STA. No heavy equipment, machinery, or materials should be placed on the backfilled STA. Livestock should not graze on the STA. Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWTS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a STA. If an effluent filter or screen has been installed in the OWTS, we recommend this filter or screen be cleaned annually, or as needed. If the OWTS consists of a pressurized pump system, we recommend the laterals be flushed annually, or as needed. The homeowner should pump the septic tank every two years, or as needed gauged by measurement of solids in the tank. Garbage disposal use should be minimized, and non-biodegradable materials should not be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste only. Page 6 ADDITIONAL CONSTRUCTION NOTES If design includes a pump, weep holes must be installed to allow pump lines to drain to minimize risk of freezing. The pump shall have an audible and visual alarm notification in the event of excessively high water conditions and shall be connected to a control breaker separate from the high water alarm breaker and from any other control system circuits. The pump system shall have a switch so the pump can be manually operated. Excavation equipment must not drive in excavation of the STA due to the potential to compact soil. Extensions should be placed on all septic tank components to allow access to them from existing grade. Backfill over the STA must be uniform and granular with no material greater than minus 3-inch. INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC must view the OWTS during construction. The OWTS observation should be performed before backfill, after placement of OWTS components. Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. ALL SERVICE septic, LLC should be notified 48 hours in advance to observe the installation. LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions described in report, ALL SERVICE septic, LLC should be notified. All OWTS construction must be according to the county regulations. Requirements not specified in this report must follow applicable county regulations.

And its patented pump vault technology eliminates the need for separate dosing tanks. This document provides detailed information on the ProPak pump vault and filter, 4-in. (100-mm) 60-Hz turbine effluent pump, and control panel. For more information on other ProPak components, see the following Orenco technical documents: • Float Switch Assemblies (NSU-MF-MF-1) • Discharge Assemblies (NTD-HV-HV-1) • Splice Boxes (NTD-SB-SB-1) • External Splice Box (NTD-SB-SB-1) Applications The Biotube ProPak is designed to filter and pump effluent to either gravity or pressurized discharge points. It is intended for use in a septic tank (one- or two-compartment) and can also be used in a pump tank. The Biotube ProPak is designed to allow the effluent filter to be removed for cleaning without the need to remove the pump vault or pump, simpli- fying servicing. Complete packages are available for on-demand or timed dosing sys- tems with flow rates of 20, 30, and 50-gpm (1.3, 1.9, and 3.2 L/sec), as well as with 50 Hz and 60 Hz power supplies.

Using a Pump Curve A pump curve helps you determine the best pump for your system. Pump curves show the relationship between flow (gpm or L/sec) and pressure (total dynamic head, or TDH), providing a graphical representation of a pump’s optimal performance range. Pumps perform best at their nominal flow rate — the value, measured in gpm, expressed by the first two numerals in an Orenco pump nomenclature. The graphs in this section show optimal pump operation ranges with a solid line. Flow flow rates outside of these ranges are shown with a dashed line. For the most accurate pump specification, use Orenco’s PumpSelect™ software.

These zones can be segments of sand filter manifolds, drainfields, or other effluent distribution systems. Distributing valve assemblies can substantially simplify the design and installation of a distribution sys- tem and reduce installation costs. This is particularly true where a distributing valve assem- bly is used instead of multiple pumps and/or electrically operated valves. Additionally, a reduction in long term operation and maintenance costs is realized due to a reduced size and/or number of pumps. More even distribution can be achieved on sloping sites by zoning laterals at equal elevations. This eliminates drainback to lower lines and the unequal distrib- ution of effluent that occurs at the beginning of a cycle. Valve Operation The valve itself has only a few moving parts, requires no electricity, and alternates automati- cally each cycle. Refer to Figure 1 for the following valve operation description. The flow of the incoming effluent forces the rubber flap disk 1 to seat against the valve bottom 2. The opening 3 in the rubber flap disk aligns with an opening in the valve bottom to allow flow to only one valve outlet. The stem 4 houses a stainless steel spring which pushes the rubber flap disk away from the valve bottom after the flow of effluent stops. The stem acts as a cam follower and rotates the rubber flap disk as the stem is raised and lowered through the cam 5. The force from the flow of effluent pushes the stem down through the cam and the stainless steel spring pushes the stem back up through the cam when the flow of effluent stops. Each linear motion of the stem allows the rubber flap disk to rotate half the distance necessary to reach the next outlet. When there is no flow, the rubber flap disk is in the “up” position and is not seated against the valve bottom. 5 4 3 2 1 Inlet Outlets Figure 1: 6000 Series Valve Orenco Automatic Distributing Valve Assemblies NTP-VA-1 Rev. 1.2, © 11/03 Orenco Systems®, Inc.

The Distributing Valve Assembly The Orenco Automatic Distributing Valve Assembly combines the distributing valve itself and sever- al other components to give a complete preassembled unit that is easy to install, monitor, and main- tain. Figure 2 shows a complete assembly. Because distributing valves with several outlets can be difficult to line up and glue together in the field, the discharge lines in the assemblies are glued in place at Orenco. The unions (1) allow removal and maintenance of the valve. The clear PVC pipe sections (2) give a visual check of which discharge line is being pressurized. The inlet ball valve (3) allows a quick, simple method to test for proper valve cycling. The ball valve also stops the flow of effluent in case the pump is activated unexpectedly during maintenance or inspection. Check valves may be necessary on the discharge lines. Use of check valves is discussed in the valve positioning section. Valve Assembly Hydraulics Liquid flowing through the valve assembly must pass through fairly small openings and make several changes in direction. Because of this, headlosses through the valve assembly are fairly high. Table 1 gives the headloss equations for several different assemblies and Figure 3 shows the graphical repre- sentations of these equations. Orenco recommends that high-head turbine pumps be used to pressur- ize the valve assemblies to ensure enough head is available for proper system operation. High-head turbine pumps are also recommended because the use of a distributing valve usually requires more frequent pump cycling. The high-head turbine pumps are designed for high cycling systems and will outlast conventional effluent pumps by a factor of 10 or more in a high cycling mode. Furthermore, the high-head turbine pump intake is 12 inches or more above the bottom of the pump and tends to prevent any settled solids from being pumped into the distribution valve and obstructing its opera- tion. A minimum flow rate through the distributing valve is required to ensure proper seating of the rubber flap disk. Minimum flow rates for the various models are given in Table 1.

However, because of the mechanical movements of the valve, it is necessary to take steps to prevent solids from reaching the distributing valve that may impede the operation of the valve. Orenco Biotube®Pump Vaults — when properly sized and installed — provide the necessary protection to prevent valve malfunction. The Biotube®pump vault accepts effluent only from the clear zone between a tank’s scum and sludge layers and then filters this effluent through a very large surface area screen cartridge. Without this protection in effluent systems, the valve has very little chance of reliable long-term operation. Figure 3: Automatic distributing valve assembly headloss curves Valve Positioning The physical position of the valve in relation to the pump and the discharge point is very important for proper valve operation. The most reliable operation occurs when the valve is placed at the high point in the system and as close to the pump as possible. The transport line between the pump and valve should be kept full if possible. If the line is empty at the beginning of each cycle, pockets of air during filling can cause random rotation of the valve. The valve is particularly vulnerable to this erratic rotation with empty lines that are long and not laid at a constant grade. An ideal valve loca- tion is shown in Figure 4. If the final discharge point is more than about 2 feet above the valve and the system does not drain back into the dosing tank, check valves should be installed on the lines immediately following the valve and a pressure release hole or line should be installed just prior to the valve. This pressure release hole or line can go into a return line to the dosing tank or to a “minidrainfield” near the valve. In order for the valve to rotate reliably, no more than about 2 feet of head should remain against the valve to allow the rubber flap disk to return to its up position. In many cases, it may take from one minute to several minutes for the pressure in the valve to be lowered enough for proper rotation to occur. Special care should be taken when installing systems controlled by programmable timers to ensure cycling does not occur too rapidly. Figure 5 illustrates a valve assembly using check valves. Pumping downhill to the valve should be avoided unless the transport line is very short and the ele- vation between the discharge line out of the tank and the valve is less than about 2 feet. If the valve is located many feet below the dosing tank, random cycling may occur while the transport line drains through the valve at the end of the cycle. A pressure sustaining valve located just before the distrib- uting valve may overcome this problem in some instances. Dosing Tank Discharge Laterals Distributing Valve Assembly Transport Line Figure 4: Ideal valve location NTP-VA-1 Rev. 1.2, © 11/03 Orenco Systems®, Inc. Page 4 of 6 System Startup Refer to the Hydrotek Valve booklet that is provided with the distributing valve assembly for the sequencing of the valve outlets. The transport line should always be flushed with clean water before installing the valve. Any sand, gravel, or other foreign objects that may have been in the pipe during installation can easily become lodged in the distributing valve, causing malfunction. With the pump running, alternately close and open the ball valve on the distributing valve assembly to check proper rotation of the valve. (Note: If check valves are used on the lines after the distribut- ing valve, the pump may need to be turned on and off to allow the pressure to be released from the valve.) If visual operation of which zone is operating is not possible, watch the clear pipe on each line for indication of which zone is operating. Maintenance Annually check for proper operation by following procedures listed in the Hydrotek Valve booklet and system startup procedures listed above. Troubleshooting 1. PROBLEM: Valve does not change or cycle to next zone or outlet CAUSE: The stem and disk assembly is not rotating when water flow is turned off and then back on. SOLUTION 1: Ensure that there is no debris inside the cam. Clean and carefully reinstall the cam. SOLUTION 2: If fewer than the maximum number of outlets are being used, check the installation of the cam. Ensure that the stem and disk assembly is not being held down by an improperly installed cam. Refer to the cam replacement instructions. h Check Valves if h>2'-0" Distributing Valve Assembly Transport Line Dosing Tank Pressure Release Line if h>2'-0" Discharge Laterals Figure 5: Valve assembly below final discharge point NTP-VA-1 Rev. 1.2, © 11/03 Orenco Systems®, Inc. Page 5 of 6 SOLUTION 3: Remove the valve top and check for proper movement of stem and disk assembly. Check for and remove any debris or foreign objects that may jam or retard the movement of the disk. SOLUTION 4: Check for freedom of movement of stem and disk assembly up and down over the center pin in bottom of valve. Scale deposits may build up on the pin and hold stem and disk assembly down. Clean pin and again check for freedom of movement. SOLUTION 5: Be sure that all operating outlets are not capped and that the flow to operating zones is not restricted in any manner. This would cause pressure to build up in the valve and lock the stem and disk assembly in the down position. SOLUTION 6: The backflow of water from uphill lines may be preventing the valve from cycling properly. This can happen when the valve is placed too far below an elevated line. If the valve cannot be placed close to the high point of the system, a check valve should be installed near the valve in the outlet line that runs uphill from the valve and a drain line installed just prior to the valve to relieve the pressure. 2. PROBLEM: Water comes out of all the valve outlets CAUSE: Stem and disk assembly not seating properly on valve outlet. SOLUTION 1: Check for sufficient water flow. A minimum flow rate is required to properly seat the disk as shown in Table 1. SOLUTION 2: Remove the valve top and check the inside walls to ensure that nothing is interfering with the up and down movement of the stem and disk assembly inside the valve. SOLUTION 3: Make sure that the operating outlets are not capped and that the flow to the operat- ing zones are not restricted in any manner. 3. PROBLEM: Valve skips outlets or zones CAUSE: Pumping into an empty transport line — especially downhill — may cause the valve to skip outlets from pockets of air allowing the rubber flap disk to raise during a cycle. SOLUTION 1: Keep the transport line full. SOLUTION 2: If the line must remain empty between cycles, use a larger diameter transport line laid at a constant grade to prevent air pockets from forming. CAUSE: The stem and disk assembly is being advanced past the desired outlet. SOLUTION 1: Ensure that the correct cam for the desired number of zones is installed and that the outlet lines are installed to the correct outlet ports of the valve as indicated by the zone numbers on the top of the cam. NTP-VA-1 Rev. 1.2, © 11/03 Orenco Systems®, Inc. Page 6 of 6 Distributing Valves General Orenco’s Automatic Distributing Valve Assemblies are mechanically operated and sequentially redirect the pump’s flow to multiple zones or cells in a distribution field. Valve actuation is accomplished by a combination of pressure and flow. Automatic Distributing Valve Assemblies allow the use of smaller horsepower pumps on large sand filters and drainfields. For example, a large community drainfield requiring 300 gpm can use a six-line Valve Assembly to reduce the pump flow rate requirement to only 50 gpm. Orenco only warrants Automatic Distributing Valves when used in conjunction with High-Head Effluent Pumps with Biotube®Pump Vaults to provide pressure and flow requirements, and to prevent debris from fouling valve operation. An inlet ball valve and a section of clear pipe and union for each outlet are provided for a complete assembly that is easy to maintain and monitor. Ideal valve location is at the high point in the system. Refer to Automatic Distributing Valve Assemblies (NTP-VA-1) for more information.

One room on the main floor of the house, did not fit a true definition of a bedroom and therefore it will be removed from the property record card. The property record card will now show 5 bedrooms instead of 6 bedrooms. However, this will not show up in the the County's Public records till May.
