Annual Backflow Testing in Madison
Most water providers require backflow assemblies to be tested at least once a year. Our certified testers connect a calibrated differential pressure gauge and check each check valve and relief valve. Test results are recorded on the provider's form and submitted for you. If the assembly passes, you are all set until next year.

RPZ assemblies protect against high-hazard cross-connections at restaurants, medical offices, car washes and buildings with chemical feed systems. They have two check valves and a relief port that discharges water if a check fails. We install, test and rebuild RPZ units from Watts, Febco, Wilkins and Apollo. Proper drainage is planned for the relief port discharge.
