Backflow Prevention in San Diego

What is a backflow preventer?

It’s a device that allows water to flow in one direction but never in the opposite direction. Its task is to prevent drinking water from being contaminated due to backflow.

This device typically extends above ground, although many were installed in underground vaults. The preferred method of installation is outside of the building and above the ground. It’s much safer for installation and maintenance. 

How does a backflow preventer work?

Water should only ever flow in one direction: into your building or your home. But sometimes, due to pressure changes in the pipes, that water can actually flow backward and seep back into the main water supply line. 

During normal operation of the backflow preventer, the pressure between the two check valves – referred to as the zone of reduced pressure – is maintained at a lower pressure than the supply pressure. If either check valve should leak, the relief valve is designed to open and discharge water to the outside, ensuring backflow never occurs.

Why do you need a backflow preventer?

There are many reasons to consider having a residential backflow preventer installed. Here are the main ones:

  1. Keeps pollutants — germs, bacteria, organic waste, and harmful chemicals — out of the water supply, which in turn makes the water look and taste clean
  2. Protects your water and sewer system from expensive repairs resulting from the damage of pipework and entry of foreign materials
  3. Compliance with the legal requirements in areas where the installation of backflow preventers is mandatory

A backflow preventer can eliminate the contaminants from your drinking water, keeping you and your family safe and healthy.
