Common backflow failures in Princeton
The failures we repair most often in Princeton are worn check valve rubber, debris holding a check open, a relief valve that will not seat and drips continuously, a corroded or seized shutoff, and freeze-cracked bodies and bonnets. Any of these will fail a test, and City of Princeton Public Works will not accept a report until the assembly passes.
Repair, re-test, and re-file in one process
Because we are both the tester and the repair crew, there is no handoff. We diagnose which component failed, quote the repair before touching anything, complete the work with manufacturer rebuild kits, re-test the assembly, and file the passing report with City of Princeton Public Works. Many Princeton repairs are finished on the same visit as the failed test.
Repair or replace?
Repair is almost always the cheaper option when the body is sound and parts are still made for the model. If the assembly is obsolete, badly corroded, undersized, or cracked through, we will tell you plainly that replacement is the better value rather than sell you a rebuild that fails next year.
