Backflow Preventer Testing in Wauwatosa
HKV Plumbing provides certified backflow preventer testing required by many Wisconsin municipalities. We use specialized equipment to check the device, making sure it properly prevents reverse flow.

Freeze and Heat Protection for Backflow Preventers in Wauwatosa, WI
Above-ground backflow assemblies are exposed to summer sun and winter cold. Frozen pipes are a regular winter risk in Wisconsin, and deep frost can even reach water service lines buried underground.

Protecting the assembly helps it pass testing and last for years.
