Our Services, Backflow Assembly

A properly working backflow assembly for your building or facility protects the city potable water supply from contamination. Since backflow assemblies are on the consumer side of the meter – the responsibility of maintenance and testing lies with the customer, not the city. Your water purveyor requires that the assembly they track be tested annually by certified testers. National Fire Control is certified in both the testing and repair of these assemblies. We are approved to work all over the Valley of the Sun.
