Double Check Valve Testing for Nolanville Homes
After a heavy spring storm in Nolanville, a below-grade double check can sit in muddy water for a long while. The boxes in the newer subdivisions are often low to the ground and partly covered by sod, so rain and soil find their way in faster than they drain out. Double check valve testing begins with pumping the box, scraping away soil and roots, and flushing all four test cocks so the gauge reads clean. Then each check is tested separately and the second shutoff is checked for a tight seal. Without that cleanup, the readings can be off and the test cocks wear out sooner.
Double checks in Nolanville are not only a homeowner item. Small offices, shops near I-14/US-190 and church grounds may use one on the landscape irrigation, and some lower-hazard domestic lines have them as well, sometimes in a concrete vault near the parking area. Hard water leaves scale on the check seats over time, which is one of the common reasons a double check starts to slip. Ants, roots and debris move into closed boxes too. Our tester notes the condition of the box, the lid and the drainage around it, so you can decide whether a fix is worth doing before the next test.
Killeen Backflow Testing is locally owned and operated, and finding a buried box by the meter is routine for us in Nolanville, so do not worry if you have never seen yours. If you do know where it is, pull back the mulch or mark the spot with a flag. Keep pets inside while the gate is open. Commercial owners should mention a locked vault lid or a vault near a drive lane. If a check fails, we explain whether cleaning, a rebuild kit or replacement makes sense, and the quote for any repair is free. Call to schedule double check valve testing in Nolanville.

Frequently Asked Questions
The double check at my Nolanville home failed. Could the buried box be the reason?
It can be part of it. A box that stays wet and full of soil lets grit work into the assembly, where it can hold a check slightly open. Scale from hard water does the same thing. A rebuild with new rubber parts and a good cleaning often brings it back. We also look at whether the box needs gravel, a new lid or raising so it stops filling up after storms.
Do I need to dig out my double check before the test?
No. You can help by finding the lid and clearing grass or mulch from the top, but our tester will open the box, pump out water and clear the soil around the assembly. In newer Nolanville subdivisions the box is often under sod near the meter, and we can locate it if you cannot. Just make sure the gate is unlocked and pets are inside on the day of the visit.
Where is my double check valve assembly located?
On most Nolanville homes with sprinklers, a double check sits in a rectangular valve box in the yard, often near the water meter or along the side of the house. On commercial properties, it may be in a vault near the street, in a mechanical room, or above ground behind a cage. If you cannot find it, our tester can usually locate it by following the line from the meter or the sprinkler controls.
Why did my double check fail the test?
The most common reasons are debris or mineral scale holding a check slightly open, a worn rubber seat or disc, or a weak spring. Sometimes the shutoff valve does not seal, which can affect the readings. Assemblies that sit underwater in a box tend to collect grit that works its way inside. We explain what failed and whether cleaning, a rebuild kit or a replacement is the sensible next step.
