Yes — Mainstream’s licensed plumbers repair, test, and replace pressure-vacuum breakers (PVBs) on residential and commercial systems. We carry common rebuild kits and replacement assemblies on the truck, so most PVB repairs are done in a single visit. Spokane requires annual testing and recordkeeping on PVBs serving irrigation systems.
PVB services we provide
- Diagnostic and field testing
- Internal seal and check repair
- Frozen-PVB replacement after winter damage
- Annual recertification testing
- Replacement when an assembly fails the test
See our pressure-vacuum breaker service for repairs, and combine it with backflow prevention when an annual test is required by Spokane.
