Backflow Preventer Repair in Addison
Backflow preventers protect drinking water from irrigation. When an RPZ weeps, freezes, or fails a test, Addison and Farmers Branch properties need a repair — not a lecture. We diagnose the assembly, rebuild or replace, and point you at testing when the city requires it.
Addison commercial and multi-family sites often have RPZ assemblies at the street or mechanical yard. A weep is not always a full failure, but a failed test is a compliance problem. We rebuild seats and springs when that is honest, and we replace when the body is shot.
Residential dual-checks and PVBs on Carrollton and Coppell lots get the same attention. We show you both shutoffs so you can kill a geyser at 2 a.m. without waiting on us.
We are repair-first. Formal certified testing may still need a licensed tester on the city’s list — we tell you when that is the path.

Soil. blackland clay and engineered fill on Tollway lots Mid-Cities north Dallas clay breaks shallow pipe and keeps valve boxes wet. We pack repairs so the next dry-then-wet cycle does not pull the fitting apart.
Housing. townhomes, mid-rise, hotel/restaurant corridor Typical irrigation failures here: parkway heads, commercial controllers, clay laterals
