Backflow Testing & Repair in Cary, Raleigh & the Triangle
Backflow testing and RPZ repair that keeps your irrigation compliant with Cary, Raleigh, and every Wake County town’s rules — and protects your drinking water.
Required on every system — and the rules vary by town
Every irrigation system in the Triangle needs a backflow preventer to keep lawn water from siphoning back into your drinking water, and every town requires it to be tested on a schedule. The catch: the schedules differ. Cary runs a three-year residential cycle (annual if you have a booster pump or chemical feed); Raleigh Water wants residential tested by July 1 every three years and commercial annually; Fuquay-Varina tests every year through BSI Online. Miss it and you get compliance notices.
We test, repair, and replace backflow assemblies to code, handle the freeze-cracked RPZs that spring brings, and coordinate the paperwork so your account stays clear. One call keeps you compliant.

Backflow FAQ
How often does my town require backflow testing?
It varies: Cary is a three-year residential cycle (annual with a booster pump/chemical feed), Raleigh residential is every three years by July 1 (commercial annual), and Fuquay-Varina is annual. We track your town’s rule.
My backflow failed the test — now what?
We repair or replace the assembly to code and coordinate the retest so your account clears. Most failures are a rebuildable RPZ or freeze damage.
Why did my RPZ crack over winter?
A hard freeze on water left in the assembly splits it — the most common spring backflow call. A fall winterization prevents it.
Do you handle commercial and HOA backflow?
Yes — annual commercial testing, repair, and replacement for HOA and multi-property systems.
