What this repair is
A leaking RPZ or double-check is a common “my whole system is dead” call after someone tightened a union with a pipe wrench. We rebuild kits when the body is good. We replace the assembly when the bronze is cracked.
January 2018 and other rare freezes cracked a lot of Houston backflows. If yours still weeps, it is not “just a drip.” We find, replace, and insulate.
Testing itself is a licensed backflow tester’s stamp. We repair so the tester can pass it. We will tell you if you also need the test booked.

- Backflow leaking at a fitting
