Got a Backflow Test Notice?

Water suppliers send these notices when a device on your property is due for its yearly test.

1. Find the Device

It is usually near the water meter, on an irrigation line, on a boiler feed line or on a fire sprinkler line.

2. Book Before the Due Date

Call us with the notice in hand. The test is a short visit with a brief water shutoff.

3. We Send the Results

We test the device, record the results and submit them to your water supplier.

Backflow Testing

A backflow preventer stops water from your property, such as irrigation water, boiler water or water used in a business, from flowing back into the public water supply when pressure drops.

Most water suppliers require testable devices to be tested every year. We test the device, record the results on your supplier’s form and submit them, so your account stays in good standing.

Irrigation Systems

Lawn sprinkler backflow preventers.

Boilers

Devices on boiler feed lines.

Fire Sprinkler Lines

Residential and commercial fire lines.

Businesses

Restaurants, offices and other commercial buildings.

Keep a copy of every test report. If your supplier asks for proof later, you will have it.

Backflow Preventer Repair & Installation

If a device fails its test, we repair it with the right parts and test it again so it passes. Old devices that cannot be repaired are replaced.

We also install new backflow preventers when you add an irrigation system, a boiler or a new commercial water line, or when your water supplier requires one.

Failed Test Repairs

Repaired and retested so it passes.

Device Replacement

For old devices that cannot be repaired.

New Installations

Irrigation, boiler and commercial lines.

Winterizing

Outdoor devices drained before freezing.

Outdoor irrigation backflow preventers can crack in a hard freeze. Have them drained or winterized before the first cold snap.

Who Needs Backflow Testing

Not every home needs a testable backflow preventer; your water supplier decides based on what is connected to your plumbing. Homes with lawn irrigation, boilers or fire sprinklers, and most businesses, usually do.

Not sure whether your property has a testable device? Look for these.
