Backflow Preventer Testing in Oak Lawn
HVM Plumbing provides certified backflow preventer testing required by many Illinois municipalities. We use calibrated equipment to check the device, making sure it properly prevents reverse flow.

Freeze and Heat Protection for Backflow Preventers in Oak Lawn, IL
Above-ground backflow assemblies are exposed to summer sun and winter cold. Most Illinois homeowners shut off and drain outdoor spigots in the fall, and many keep cabinet doors open and faucets dripping on the coldest nights. 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 for years.
