About Irrigation Backflow Testing
Every automatic lawn sprinkler system that connects to the public water supply needs a backflow preventer. Sprinkler lines sit in soil that holds fertilizer, weed killer, pet waste and standing water, and if pressure in the street drops, that water could be drawn back toward your kitchen tap. In Killeen, most residential systems use a pressure vacuum breaker mounted above ground near the house or a double check valve assembly in a green valve box in the yard. Irrigation backflow testing confirms that whichever device you have still closes and seals the way it should.
Many Killeen homeowners first hear about backflow when a letter from the water provider says a test is due. Newer subdivisions around town often have sprinkler systems put in by the builder, and the testing requirement passes to each new owner. Our weather is hard on these devices. Summer heat dries out rubber parts, hard water leaves scale on seats, and a sudden freeze can split the brass body of an exposed vacuum breaker overnight. HOAs face the same issues across common areas, entry medians and pool landscaping, often with several devices to keep track of.
On arrival, our tester finds the device, checks the area for leaks or damage, and confirms which type it is. For a pressure vacuum breaker, we test the check valve and the air inlet to make sure the inlet opens at the right point. For a double check in a box, we may need to pump out water and clear dirt so the test cocks are reachable. We run the full test with a calibrated kit, record the readings, and turn the sprinkler supply back on. If the device fails, we show you why and talk through repair.
To prepare, clear plants away from the vacuum breaker and make sure the valve box lid is visible and not buried under mulch or sod. If your system is winterized, let us know so we can plan the test once water is back on. Many homeowners like to test in spring, right when they start the system up for the season, so any problems are found before summer watering. Call us or send the form to schedule irrigation backflow testing for your Killeen home or HOA, and we will confirm a visit time with you.

Common Questions
Frequently Asked Questions
Why does my lawn sprinkler system need a backflow test?
Sprinkler water sits in pipes buried in soil that can contain fertilizer, chemicals and bacteria. The backflow preventer keeps that water from flowing back into the drinking water supply if pressure drops. Because the device has springs and rubber seals that wear over time, most water providers require a test after installation and then on a regular schedule, often once a year. Your notice will show the due date for your Killeen home.
When is the best time of year to test an irrigation backflow preventer?
Spring is a popular choice, since it lines up with turning the sprinkler system back on after winter. Testing then catches freeze damage or worn parts before the heavy summer watering season. That said, the right time is whenever your water provider says the test is due. If your notice arrives while the system is shut down for winter, call us and we can plan around it.
How do I protect my sprinkler backflow preventer from freezing?
For an above-ground pressure vacuum breaker, the most reliable approach is to shut off the supply valve, open the test cocks to drain the device, and cover it with an insulated bag or enclosure before a hard freeze. Wrapping it without draining helps less. Double checks in valve boxes are usually better protected, but they can still freeze in a long cold spell. We can show you the steps during your test.
Can you test my backflow preventer if the sprinkler system is shut off?
We need water pressure at the device to run a proper test, so the supply valve has to be on. If your system has been off for the season, our tester can open the supply valve, check for leaks and then run the test, as long as the device and pipes are not damaged. If the vacuum breaker cracked during a freeze, we will find that quickly and talk through repair or replacement first.
