Backflow Testing and Repair

What it is

Your sprinkler system connects to the same water line as your kitchen tap. Fertilizer, soil and stagnant water sit in the irrigation pipes. A backflow preventer is a set of check valves that stops that water from being pulled back into the house line if pressure drops. Most residential systems in Dallas use a pressure vacuum breaker near the house or a double check assembly in a box.

Common problems

Water spraying from the top of the device when the system starts
A crack in the brass body after a hard freeze
A device buried in a bed or under a shrub that nobody can reach
A test notice from the water provider

Testing

Backflow devices are tested by a licensed backflow prevention assembly tester with a gauge kit. If your water provider sends a notice, call us with the deadline and we will schedule it. Read backflow preventer basics for more.

Questions people ask us

How often does it need testing?

That depends on the water provider and the type of device. Check the notice you received, or call us and we will help you sort it out.

Can I cover it in winter?

Yes. An insulated cover helps, but in a hard freeze the safest move is to shut off and drain the device. See our freeze protection page.
