What backflow is

Keeping your waterfrom flowing backward.

A backflow preventer is a valve that stops water from your irrigation system, boiler or other equipment from being pulled back into the drinking water supply if pressure drops.

Municipalities require many of these devices to be tested every year by a certified tester. If you got a letter, your device is on their list.

Lawn sprinkler system→Usually needs an annual test
Boiler or hydronic heating→Often has a backflow device on the fill line
Pool or hot tub fill line→May need one
Got a city letter→Book before the due date on it

Have your letter handy?

Book a test before the due date. We will test, file the report and tell you the result the same day.
