What is a Backflow Test all about and why are Backflow Preventers important?
Backflow Words and Terms
Backflow is the undesirable reversal of the flow of water and/or other substances into the distribution pipes of the potable supply of water from any source or sources.
Backflow preventers defend the public drinking water system against entry of pollution or contamination from an end user’s system by means of backpressure or back-siphonage. Backflow preventers must be tested regularly to ensure effective protection.
