The double check valve located after the pressure tanks is leaking. Replace or repair the check <br /> valve as necessary. Please note that a check valve to prevent backflow into the well is <br /> recommended on the well discharge line prior to the pressure tanks. However, the valve does <br /> not need to be a testable device, such as a double check valve. <br /> 2. The pump house floor below the leaky double check valve is rotting and shows recent pest <br /> activity. Please repair the check valve as mentioned in comment 41 and repair the floor to <br /> prevent pests from entering the pump house. <br /> 3. Your cross connection control program was approved by this office on September 20, 2004. Be <br /> reminded, as part of that program, to inspect your distribution system at least once annually and <br /> install cross connection or backflow prevention devices as needed. At a minimum, atmospheric <br /> vacuum breakers must be installed on all threaded hose bibs that don't have built-in anti-siphon <br /> capability. If you have any "testable"devices,they must be inspected and tagged every year by <br /> a certified technician. You are required to keep records of your inspections for ten years and <br /> have them available for review upon request. <br /> vIRGINIA <br /> VDHODF EALTHNT <br /> Protecting You and Your Environment <br />
