WHAT IS BACKFLOW PREVENTION?

Backflow occurs when contaminated water flows backward into the clean water supply due to changes in pressure, such as a burst pipe, heavy water demand, or a drop in municipal pressure.

To prevent this, professional backflow prevention devices stop contaminated water from entering your potable water system, helping protect your home, business, and the public water supply.

Common risks include:

Chemicals From Irrigation Systems

Bacteria From Commercial Equipment

Stagnant or Contaminated Water
