A Note About Backflow Prevention
Beginning in 2007, water purveyors in Washington were required by Washington State Administra-tive Code (WAC 246-290-490) to establish a cross-connection control program to prevent contami-nation of our public drinking water system by unintended backflow. Although rare, the possibility of contamination through cross-connection does exist and is a very real threat to all of us! Water can reverse its flow (backflow) when there is a severe drop in pressure. Such a drop in pressure could be caused by a water main break, several hydrants being opened during a fire, or other events. When the direction of flow is reversed, all the water in your property’s plumbing system could flow back into the public water system. If there is a backflow event while you have a hose underwater in the horse trough or pool, any bacteria or chemicals in your trough or pool is now part of the public drinking water. If you have a hose in your radiator while flushing it, that water and the chemicals are now part of the drinking water. If your lawn sprinkler system does not have backflow protec-tion, fertilizers and weed killer are now part of the drinking water. Not a pleasant thought!
Approximately one-fifth of our members have special plumbing features on their premises that re-quire backflow prevention measures. These plumbing features include fire sprinklers, lawn sprin-klers, hydronic heating, solar heating, photo labs, other water sources, and water softeners. These members are required to have backflow prevention assemblies installed to prevent backflow of the used water in the event of a loss in pressure. If you install any of these special plumbing features, please call our office so that we may discuss the precautions that must be taken. The main require-ment will be to install an approved backflow prevention assembly immediately after the water me-ter, on your side, to isolate your premises. The backflow prevention assembly will then need to be tested annually by a certified backflow assembly tester (BAT). For your convenience, Heights Wa-ter contracts with certified testers each summer to arrange for everyone’s testing to be done at the same time, at reduced rates.
Even if you don’t have any special plumbing features like those described above, remember to keep the garden hose out of the pool and car washing bucket. Always maintain an air gap between the hose and the vessel it is filling, or better yet, install a vacuum breaker at each hose bib. It is sim-ple, inexpensive, and could save lives!
Cross-connection control is a simple way to help keep our water safe for yourself and your neigh-bors. Feel free to call or stop by the office if you have any questions!
