Reduced Pressure Zone Assembly Service in Watford City, ND
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 designed for the relief port discharge.
Freeze and Heat Protection for Backflow Preventers in Watford City, ND
Above-ground backflow assemblies are exposed to summer sun and winter cold. Frozen pipes are a serious and regular winter risk in North Dakota, and a single cold night can split a line in an exterior wall. Freezing can crack bodies and bonnets, while UV exposure breaks down plastic parts. We install insulated pouches, heated enclosures or lockable cages as needed. Protecting the assembly helps it pass testing and last longer.

Annual Backflow Testing in Watford City
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.
