Why It Matters
Backflow happens when a drop in water pressure lets water flow backward into the clean supply, carrying contaminants from irrigation lines or other sources. A backflow prevention device stops that reverse flow.
We test your backflow prevention device to make sure it’s working properly and helping prevent contaminated water from entering your clean water supply. Routine testing also helps meet applicable local water safety requirements.
