Backflow Preventer Repair and Rebuild in Lawrence, KS

We isolate the assembly, disassemble it and replace the worn parts with the manufacturer rebuild kit. Then we retest to verify it passes. Rebuilding usually costs much less than replacing the entire assembly.
Freeze and Heat Protection for Backflow Preventers in Lawrence, KS
Above-ground backflow assemblies are exposed to summer sun and winter cold. Sudden arctic fronts can drop temperatures quickly, so disconnecting hoses and protecting outdoor spigots before winter is a smart routine. 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.
