How do backflow preventers work?

Backflow preventers are designed to prevent dirty or contaminated water from entering your potable water supply. Having backflow in your plumbing can prevent serious health issues, so it’s vital that you have backflow preventers installed and that they are property functioning.

There are two main ways backflow can occur:

  1. Back pressure – this occurs when the pressure in the dirty water is greater than the pressure of the clean water.
  2. Back siphoning – this occurs when the supply is interrupted or drained down. This type of backflow is common when there are water main breaks or the sprinkler system has gone off.

Your backflow preventer will act as a one-way valve that allows contaminated water to go out but not in. Backflow preventers are always automatic, so as long as they are in good condition, they will operate as intended all the time. If backflow occurs, it’s vital that you call an experienced plumber right away. Contact with contaminated water can lead to serious illness.

Backflow preventer testing & repair

You don’t want to find out your backflow preventer isn’t working in an emergency—scheduling annual testing is highly recommended. Commercial buildings are required by law to have their backflow preventers tested annually and replaced or rebuilt every five years.
