Why Colleyville requires an irrigation backflow test
Sprinkler heads sit in soil, fertilizer, and pet waste. If pressure in the Colleyville main drops — a hydrant flush, a water main break — water can be siphoned backward out of your yard and into the drinking water system. The backflow assembly on your irrigation line prevents that, and City of Colleyville Public Works requires proof each year that it still works.
Where your assembly is and what we do
Most Colleyville homes have a double check or pressure vacuum breaker assembly near the water meter, in a green in-ground box, or above ground close to the house. Our technician isolates it, tests each check with calibrated gauges, notes the results, and restores the system. You do not have to be home — just leave the gate unlocked or send a gate code. On-site time is typically 20 to 30 minutes.
Freeze damage and failed assemblies in Colleyville
The most common failure we see in Colleyville is a cracked bonnet or split body from a hard freeze, followed by debris fouling a check. We carry common irrigation parts, so a failed test often becomes a same-visit repair and re-test. Once it passes, we submit the report to City of Colleyville Public Works and you are done for another year.
What irrigation backflow testing looks like in Colleyville
Colleyville irrigation assemblies are large and heavily zoned — often 2-inch or larger devices serving eight or more zones across an acre or more. That size means higher flow, more grit, and relief valves that foul faster than a small suburban device. Where a well feeds any part of the system, a double check is not sufficient and we will tell you so before testing.
Colleyville water authority: City of Colleyville Public Works
Colleyville is an acreage community, and that changes backflow work substantially. One-acre and larger lots along Glade Road and Whittier Heights run large multi-zone irrigation systems, private wells next to city water, pool and pond fill lines, and occasionally livestock water — all cross-connections the City of Colleyville expects to see protected and tested every year.
We submit your passing irrigation backflow testing report directly to City of Colleyville Public Works — no paperwork on your end. City of Colleyville Public Works requires reduced pressure protection wherever a well, pond, or other auxiliary supply exists alongside the city connection, tested annually.
