Backflow Repair — FAQs
Do you perform backflow testing?
We focus on repair. If a test is required, we can coordinate a third‑party certified tester after the repair.
Why is my PVB vent “spitting” water?
Common causes include a worn bonnet/poppet, debris in the checks, or freeze damage. A rebuild kit usually resolves it.
My RPZ is dumping water from the relief—normal?
Constant discharge indicates a failed check or debris on the seat. We can service the internals and reseal the assembly.
Can you repair freeze cracks?
Yes. We replace cracked housings/bonnets and fix damaged risers or unions, then pressure‑check the system.
Which brands do you service?
Watts, Febco, Zurn Wilkins, Apollo/Conbraco, and others. We carry common rebuild kits for popular models.
