Centennial Backflow Prevention

Centennial backflow prevention devices protect your water supply from contamination. The law requires you to perform backflow testing at least once a year to ensure the effectiveness of your preventer. Here at Done Plumbing & Heating, we provide accurate testing and prompt repairs to the Centennial area and beyond. So when you need to prevent backflow and water pollution, call us at (833) 539-9153 or fill out our online form for our services.

How We Perform Centennial Backflow Prevention

Backflow preventers are essential appliances that ensure your water is safe to use. But if your backflow preventer malfunctions, it may contaminate the public water supply. That’s why only certified professionals are allowed to work on your devices. At Done Plumbing & Heating, our plumbers are fully licensed, insured, and qualified to work on your system.

It only takes around 30 minutes for us to test your backflow prevention in Centennial. We streamline the process with efficient procedures, so there is little to no interruption of your day. During an inspection, our plumbers:

  • Check if valves open and close properly
  • Examine leakage and gauge movement
  • Test the pressure
  • Ensure proper activation of the system
  • Look for other signs of malfunction

Centennial Backflow Preventer Repair

If your preventer meets the required standards, then our job is finished. If not, our team provides Centennial backflow preventer repair, replacement, and installation to get it fixed. First, we’ll check for the type of backflow that is occurring:

  • Back pressure occurs when non-potable water pressure exceeds potable water pressure. For example, devices like boilers or sprinkler systems can create higher pressure than your potable water supply, leading to backflow.
  • Back siphonage happens when there’s a loss of pressure in your clean water supply, sucking contaminated water backward. This backflow usually occurs when high water usage exceeds the amount supplied, like during firefighting.

We’re ready to address whichever type of backflow your system is experiencing. Don’t let a defective preventer contaminate your water; contact us for our backflow prevention services today!

Centennial Backflow Preventer Installation

If your backflow preventer is beyond repair, you may need Centennial backflow preventer installation and replacement. We’ll get your backflow prevention system working by installing a brand new preventer on your property. Backflow preventers tend to last long, but Centennial backflow preventer replacement is necessary if your device no longer works.

You can’t skimp on repairs and replacement for something as important as fresh, usable water. If we determine that your device needs replacing during annual backflow testing, we’ll guide you through replacement options best suited for you.

“This past week I had the need for a plumber and I reviewed the telephone book and selected from the advertisements your company to attend to the matter. The company sent Austin Steinbach to attend to and review the problem. He is a very knowledgeable young man who communicates well and does his work in a very thorough and professional manner. I was very satisfied with his service. Mr. Steinbech is a credit to your company. Very often in communities someone asks whether they are aware of a plumber or other technician that can be recommended. In this regard, I am comfortable in recommending Mr. Steinbech and your company. Thank you for the service rendered.”

“Quick & competent work done to high satisfaction. Darrell Begay provided quick service and very professional work when he came to install a new toilet seat. We had not been able to do the work ourselves, so it was a relief to have Darrell and Done Plumbing get here so quickly to take care of the task. We appreciate all Done as done for us”

~ Lindsay B. Centennial, CO

“Just a note to tell you of our recent positive experience with Kieth Croft. We found him to be friendly, knowledgeable, & efficient. When an issue arose with the clean-outs, Kieth quickly resolved it to our satisfaction & to the way he had previously described. From the estimate to the conclusion of the project we had confidence in Kieth. He is a good ambassador for your company.”

~ Janice & Roald B Lakewood, CO

“Just a note of thanks for being the Best plumbing and heating company. I have used you often and have been impressed every time. I called for a drain cleaning and was told a technician could come the same day. He arrived an hour ealier than was quoted, was very professional and did a great job at a very reasonable price with my coupon that he honored. I would never use another company and would recommend you to anybody that needs help. The technician that did such a great job was Austin, but every technician you have sent has been the best. Thanks again for such a wonderful company”

~ Karla W Golden, CO

“It was very professional, prompt & the technician explained many things well. Very happy throughout the whole process – from the customer service rep who answered the phone this morning to the technician explaining building codes to me.
