Irrigation Backflow Testing in Saint Louis, MO

Sprinkler systems are the most common reason a homeowner gets a backflow test letter. Heads sit in soil, fertilizer and pet waste, and a pressure drop on the main can pull that water back into the house supply.

Irrigation backflow testing covers whatever your system uses: a PVB on most homes, an RPZ where fertilizer injection is present, or a double check on some commercial sites.

Timing matters. In cold regions the device has to be charged and tested after spring start-up, then drained before the first hard freeze. Testing a winterized PVB is not possible, so the test lands between those two dates.

A tester also looks at the install. A PVB under 12 inches of rise, a missing union or a test cock painted shut are all common on older lawns.

Grizzly Backflow & Plumbing connects you with testers in Saint Louis, MO who handle irrigation backflow testing, file the report and fix small problems on the spot when parts allow. Call (833) 990-5874 for backflow prevention on your sprinkler system.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Irrigation Backflow Testing in Saint Louis, MO.

Talk to a person
Who is allowed to test my backflow device?
A tester who holds a backflow tester certification recognized by your state or your water utility. Many utilities keep an approved tester list and reject reports signed by anyone not on it.
What happens if I miss the backflow test deadline?
Utilities usually send a second notice, and after that some add a fee or schedule a service shutoff. Calling (833) 990-5874 before the deadline is the simplest way to avoid it.
Will my water be off during the test?
Yes, briefly. The tester closes the shutoff valves on the assembly while reading the checks, so water downstream of the device is off until the test is done.
Does my lawn sprinkler system in Saint Louis, MO need a backflow preventer?
Almost every US plumbing code requires one on irrigation, since fertilizer, pesticide and standing water at the heads can siphon back. The device type depends on local code and how the system is laid out.
How much does backflow testing cost in Saint Louis, MO?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Saint Louis, MO.
