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.

Quick and easy appointment setting. Excellent service. Acute attention to details in making sure the repair went smoothly. The greatest experience we’ve had with plumbing repair! Cannot recommend Pridemark Plumbing enough! Adding photos of the mess under the sink before Donnie got to it and after. A fully functional sink and a new faucet!

Wanted to replace a large 75 gallon water heater and looked into alternatives including high end condensing units. After contact with another company which I was not happy with, found Pridemark on Navien’s website and contacted him. Could not be more pleased with the result. Donnie is a consummate professional and he works hard to maintain that reputation. He installed the tankless Navien, a water filtration system, and an alternative to traditional water softening. Pleased with all. Donnie recognizes the need for the right tools on the job and spends the money to outfit his truck with tools that are the right match for the job and which allow him to finish the job in a timely manner. If the first place you look when seeking a technician for your home is “discount electrical” or “discount plumbing” then Donnie may not be a good fit for you. If the first place you look is for a highly rated professional, then Donnie will be a good fit. He is well trained, knowledgeable, has the right tools for the job, and he charges a fair price for a service he knows he is qualified to deliver. We recommend him to our friends and have no reservations about doing so. You won’t get a “cheap plumber” if you hire Donnie; you will get a really good plumber who will do his best to make you a satisfied customer.Update August 2021. Donnie came to service the tankless water heater and also lift a toilet to replace seeping wax seal. There was some dislodged material that got into the system (a check valve did not catch it) and blocked the pump so that it would not recirculate. Donnie was here the next day, diagnosed and repaired the unit. Since it was still under warranty he would not let me pay him for his time and materials. He also added a second copper valve to back up the check valve…and would not take any compensation for the parts or the time. I told him he didn’t bid that as part of the original install. He should have added the backup protection he said (not called for by manurfacturer’s installation guide), so he wouldn’t take payment. As I said above, Donnie is not your “budget” or “cheap” plumber but if you want a quality job and a technician who will be there quickly should something go wrong… you can look around, but Donnie is the guy to use FIRST. After what he found and corrected with the one toilet, we are going to schedule him to come back and do the other toilets soon. Donnie is going to go out of his way in order to make you a satisfied customer. We highly recommend.

I have had Pridemark Plumbing out on a couple of occasions. They respond to our needs, clearly communicate, and are very nice. I always recommend them because they are honest about what we need and don’t need for our situation.

Seriously the best plumbing company I have ever ever used. This is the second time I have used Pridemark and the plumber, Donnie, came both times. This time with his apprentice who was also great. They are simply the best. On time, thorough, knows their stuff, and Donnie is seriously the best most competent, fair and kindest technician I’ve ever encountered. I immediately called my father to recommend Pridemark to him and will continue to do so to anyone else I know. Great, great company. Thank you so much for the positive experience and quality work.

I made a mistake and didn’t look into the company that I had install my tankless water heater. After realizing it wasn’t working properly, I contacted Pridemark Plumbing to see if they knew what was wrong. It turns out the tankless was installed incorrectly and could have put my family’s life in danger. Needless to say I had this company fix it and all is in working order now. I will not be making that mistake again. Please make sure you do your research on these companies that claim to be experts. This could have been a nightmare. I’m so thankful for Pridemark Plumbing for coming to the rescue.

Wow, these guys really showed up. I wasn’t sure what to expect as I have had bad experiences with plumbers before, but everything about these guys from their clean uniforms to their expertise was really surprising to me. I honestly didn’t know a plumbing company could be so professional. No doubt I’ll be using them again.
