Annual Backflow Testing in Las Cruces
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 done until next year.
Reduced Pressure Zone Assembly Service in Las Cruces, NM
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.
Irrigation Backflow Preventer Installation in Las Cruces
Sprinkler and drip systems are one of the most common sources of cross-connection risk because they sit in soil with fertilizers and pesticides. Many systems use a pressure vacuum breaker or a reduced pressure assembly installed above grade. We size and install the correct device and set it at the proper height. Insulated covers or enclosures help protect it from weather and theft.
Freeze and Heat Protection for Backflow Preventers in Las Cruces, NM
Above-ground backflow assemblies are exposed to summer sun and winter cold. Even in milder parts of the state, clear winter nights can drop below freezing, so outdoor spigots and evaporative cooler lines need draining each fall. 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.
