Protecting Your Water Supply with Certified Backflow Services

Backflow Replacement & Testing

Water contamination is a serious health risk, and backflow prevention is essential to maintaining a safe and clean water supply. At Pride Plumbing, Inc., we specialize in backflow prevention, testing, repair, and replacement to ensure your home, business, or property remains compliant with local and state regulations.

What is Backflow?

Backflow occurs when the normal flow of water in your plumbing system reverses, allowing contaminated water to enter your clean drinking water supply. This can happen due to:


  • Backsiphonage – A sudden drop in water pressure that pulls contaminated water into the potable water system.
  • Backpressure – When downstream pressure is higher than the supply pressure, causing pollutants to be pushed back into the drinking water supply.


Contaminants can include fertilizers, pesticides, chemicals, human waste, and other hazardous substances, making backflow prevention crucial for public health and safety.

Why Backflow Prevention is Required in California

The State of California requires annual backflow testing and certification for many commercial and residential properties. Property owners must ensure their backflow prevention devices are properly installed and functioning to prevent cross-contamination. Non-compliance can result in fines, service disruptions, or unsafe water conditions.

1. Backflow Testing

State and local regulations require annual backflow prevention device testing to ensure proper function. Our certified technicians use specialized equipment to:

✔ Inspect your backflow prevention device for leaks or failures

✔ Measure pressure levels to ensure proper function

✔ Provide a detailed compliance report

✔ Submit test results to the appropriate authorities


Annual testing is required to maintain compliance with California health and plumbing codes.


2. Backflow Prevention Device Installation

If your property does not have a backflow prevention system, we can install one that meets city and state requirements. We offer various types of backflow prevention assemblies, including:

✔ Reduced Pressure Zone (RPZ) Assemblies

✔ Double Check Valve Assemblies (DCVA)

✔ Pressure Vacuum Breaker Assemblies (PVB)

✔ Atmospheric Vacuum Breakers (AVB)


We will assess your property’s needs and install the right system to ensure maximum protection.

3. Backflow Device Repair & Replacement

Over time, backflow preventers can wear out, corrode, or fail, requiring repair or replacement. Common signs of a failing backflow prevention system include:


  • Sudden changes in water pressure
  • Discolored or foul-smelling water
  • Leaking backflow preventer
  • Slow drainage or unexplained water contamination


If your backflow device is outdated or damaged, we provide fast, efficient replacements to keep your water system secure.


4. Compliance & Certification Assistance

We help homeowners, businesses, and property managers stay compliant by:
