Backflow Repair Services

We're here when things go wrong.

We have 24/7 emergency services to keep you safe.


When your backflow device isn't working right, it can let dirty water flow back into your clean supply, which is a serious health risk.

This can happen if parts wear out, if the device is damaged, or doesn't get serviced regularly.

Our service team checks exactly what's wrong and either replaces the faulty parts or installs a new device if needed, making sure your water stays safe and complies with city rules and regulations.

We handle the entire process for you.

Backflow Protection

Your water safety is our #1 priority.

24/7 emergency services to keep you safe.


Backflow protection is really important for keeping your drinking water safe.

It's about making sure that water only flows in one direction – into your home or business – and doesn't accidentally flow backward and pick up contaminants.

What our clients say

Our clients say nice things about our service...

Fantastic Employees!

I haven't worked with this company directly but have a recent experience with one of their employees that says a lot about how they approach service. I got a flat tire on a very busy road during a rainstorm. Rusty, a company employee, saw my situation and turned around to offer assistance. I quickly accepted his kind offer and he had the flat tire changed in about 15 minutes. Really saved the day and was very friendly while doing the work. So, if you're in need of All Pro Backflow's services, I'm confident based on Rusty's approach that they will help solve whatever needs addressing.

FAQ's

Backflow Questions? We've got answers.

We've been around since 1998. We've seen a thing or two.

What is backflow?

Backflow is the unwanted reversal of water flow and contaminants from any location into your drinking water system's distribution pipes.

What is a backflow assembly?

A backflow preventer/assembly is a plumbing device installed to stop contaminated water from flowing backward. When properly installed, tested, and maintained, these devices protect your community's water supply.

Am I required to have a backflow assembly?

Control of cross-contamination through backflow prevention is required in most situations, including irrigation water meters, multi-family housing, and all commercial and industrial properties.

Does my backflow assembly need to be tested?

Yes, if you received a backflow test notice from your Water District, you must have the test done within the given timeframe. Even without a notice, it's a good idea to test each backflow assembly at least once a year.

What happens if I do not have my backflow tested?

Failing to test your backflow assembly can lead to fines for not following the rules, and your water service might even be stopped or terminated to protect the public water system.

Why do I need my backflow assembly tested annually?

California law requires backflow preventers to be tested at least once a year to ensure drinking water safety. Regular testing also helps avoid bigger, more expensive repairs later on.

Does my water get interrupted during a test?

In most cases, water service needs to be interrupted for five to ten minutes to properly service your backflow preventer.
