The find
An after-hours call for water in a backflow vault turned up damaged packing and corroded bolts on the device. Left alone, the assembly would have failed its next test outright; in the meantime it was leaking into the vault and not seating properly under reverse pressure.
The repair
We isolated the assembly, replaced the bolts, relubricated the packing, and reseated the checks. The device went back into service immediately and was scheduled for a follow-up TCEQ-compliant test to confirm the rebuild held.
What this looks like at scale
Backflow assemblies don’t fail one component at a time — once the seal is compromised, every adjacent fastener and gasket starts taking water. Catching the failure mode early and rebuilding correctly is the cheap path. Waiting until the device frankly won’t pass adds an after-hours dispatch, vault pumping, and parts sourced under pressure.
