Most homeowners assume that water only flows one way through their pipes: into the house. However, sudden changes in water pressure can cause a dangerous reversal known as “backflow.” This can pull contaminated water from your irrigation system, swimming pool, or garden hose back into your clean drinking water supply. In many parts of Riverside County, backflow prevention devices are required by law to protect the public water system.

At Davis Plumbing, we specialize in the installation and testing of these critical safety devices. Here is what every 951 property owner needs to know.

1. How Backflow Happens

Backflow usually occurs during a “back-pressure” or “back-siphonage” event. This can be caused by a water main break down the street, a heavy demand from fire hydrants nearby, or a pump failure in your septic system design. Without a functioning preventer, soaps, fertilizers, and even waste can enter your home’s faucets.

2. Common Sources of Contamination

  • Irrigation Systems: Sprinkler heads sit in dirt and are often exposed to fertilizers and pesticides.
  • Swimming Pools: Pool chemicals should never mix with your kitchen or bathroom water.
  • Boilers and Cooling Towers: Chemical treatments used in HVAC systems must be kept separate.

3. Annual Testing Requirements

Because these devices have internal seals and springs that wear out, most local water districts in the 951 require annual backflow testing. A certified technician must verify that the device is working correctly and submit the results to the city. Failure to do so can lead to fines or the water being shut off to your property.

4. Professional Installation and Repair

Backflow preventers are complex valves. Whether you need a new installation for a remodel or a plumbing repair on an existing unit, it’s vital to hire a licensed professional who understands local Riverside County codes.
