RPZ Valve An Instant Connection To Danger?

Reduced pressure zone assemblies are used to keep contamination or pollution out of your water. Think of water back flow as an unwanted flow in the opposite direction you need. In a backflow situation the "dirty water" could flow back inside and contaminate your drinking water.

Your backflow preventer could be in perfect working order, but if your neighbor's backflow preventer fails, they could be letting fertilizer, soap, stagnant water, and much more into your public water supply. Order a certified backflow preventer test every year. It's law and a type of insurance.


What Is A Backflow Test?

Essentially, any crossed connection in your water system could allow for back flow. A water cross connection is where a non-drinking water substance (sometimes deadly) has the ability to come in contact with drinking water.

Backflow test checks your RPZ valve by assessing its pressure levels. When the pressure in a tank or trough dips below the water system’s pressure, this could pull contaminated water into your drinking or bathing water. Your "dirty water" could contaminate the public drinking water, leading to potential liability. For this reason, testing guarantees the water you use is safe and sterile.

Water pressure is a real beast to control. Usually main water piping has a RPZ, fire sprinkler system RPZ, and landscape watering RPZ. All require a state certified inspection every year to ensure they are working safely. Each town has its own safety code. PDM experts will report test results and file city paperwork.
