Backflow Prevention and Testing Services

Backflow prevention devices and systems are required in commercial properties and multi-family buildings, as well as certain single-family residences.

These systems are designed to protect both public and private water supplies by preventing accidental cross-connections between potable and non-potable water.

As a result, many properties across Surprise and the West Valley are required to have a properly working backflow prevention system installed.

Does Your Surprise, AZ Home Require a Backflow Prevention Device?

Not every residential property needs a backflow prevention system. But if your home features an irrigation system (such as lawn sprinklers) or well system, you may be required by the municipality to install a prevention device.

What is Backflow? What Causes It?

Backflow is the result of a cross-connection between wastewater and clean, potable water supplies. Without a backflow prevention system in place, cross-connections can cause the wastewater supply to flow in reverse and enter the city’s water line or your private water supply.

Backpressure and backsiphonage are the main causes of backflow: backpressure typically develops if water pressure in your plumbing system ends up being greater than the water pressure in the city’s main line; backsiphonage, on the other hand, is the result of damage in the municipal water line or an illegally opened fire hydrant.

In both cases, having an efficient backflow prevention system will help keep wastewater or contaminated water out of our potable water supplies.

Installing and Testing Your Backflow Prevention Device

Once installed, backflow prevention devices become a major part of your plumbing system and are responsible for keeping your (and the community’s) water supply safe from harmful cross-connections. This is why it’s important to work with a licensed plumbing professional who is a certified and approved backflow tester in Surprise, AZ.

Our experts at Pridemark Plumbing can help you with all of your backflow prevention needs, from installing new devices to performing required annual testing.

We will assess your needs and make sure an approved device is installed on your property. Once your device is installed, it’s your responsibility to schedule annual testing. You will typically receive a reminder from the city a few weeks before the test is due.

After testing is complete, we will go over the results with you and let you know if any repairs or replacements are needed. We will also send a report of the test to the city so your home or business continues to remain compliant.

We needed our tankless water heater checked, flushed and descaled. Pridemark did a great job. Also checked and fixed a toilet. Donnie, the owner is also a very good communicator. Prices were reasonable. I will definitely recommend to friends and use again if needed.

They’ve saved us twice now. First was a leak inside a wall, second was a very clogged kitchen sink. Both times Donnie has been great. He is quick, responsive, trustworthy, and knowledgeable. Would highly recommend.
