Raise your hand if you know what a water check valve is.

And yet a water check valve is responsible for ensuring that you have potable water to use for showering, bathing, doing dishes and doing laundry.

A water check valve is a device used to prevent backflow, that dangerous situation where contaminated water backflows and enters into the water supply.  Check valves installed in the correct location are required by federal, state and city jurisdictions.

The next time you need backflow testing, installation or repair, call City Backflow Testing for affordable backflow testing.
