What Is a Backflow Device?

Backflow prevention is key to ensuring the safety of the public water system. Your backflow device keeps contaminated water from returning to your potable water supply. This device is installed at the point where your property connects to the water source.

A backflow device is a valve that allows internal flow in only one direction. The device allows water to flow out of the public supply and into the private system. A properly functioning backflow device prevents water from flowing in the opposite direction. Most businesses and residences are legally required to maintain a backflow device due to the various water uses that could potentially cause cross contamination.

If you have a swimming pool or lawn irrigation system but your backflow device is not working properly, there is potential for cross contamination. A drop in water pressure in the public water supply can also cause backflow problems.

When Do You Need to Call for Repair or Replacement?

Contact us for immediate backflow device repair or replacement if the following occur:

  • Valve starts to spit from the vent, affecting your supply and downstream pressure
  • Sudden drop in valve pressure due to a faulty strainer; this may also indicate a valve that is too small to take on the flow of water
  • The valve has been installed backwards, preventing water from flowing downstream
  • Water spilling due to problems with the check valves and springs
  • Valve continues to have problems after service

These are some of the more common backflow device problems that property owners may experience. If you notice these or other problems, contact us for the right solution.

A poorly working backflow device can affect your community’s water supply. Make sure your device continues to comply with local code by contacting your Pipe Wrench Plumbing, Heating & Cooling, Inc. technician for timely repair and replacement.

Call us today at (865) 583-3957 for quality service. Your device will be repaired correctly the first time, or you don’t pay a dime!

What Our Customers Are Saying

"Adam Bunch and Salwan were our technicians. They were very professional, courteous, thorough, and we feel they did a very good job. They were both very personable, friendly, and genuinely take pride in their profession. We feel very confident in the work that they did. We have an older home built in the mid 1980s with old, failing hex water lines along with some copper fittings. We needed new lines installed and they did a good job with it. I would recommend them to other people. In comparison, the price is more expensive than some other businesses in this area for the same work, but we feel that the guarantee that comes with Pipe Wrench work brings accountability. We will use this service again in the future."

"Very timely. The first time I used this service I had a thermostat replaced in my hot water heater. They were quick and professional and was fairly priced. I'm in the middle of my second experience at a relatives home for hot water heater replacement. They were able to get a tech out for evaluation the same day we called (today) about a problem and have scheduled the replacement for the next day. The tech was polite, professional and advised us of all our options in a way that was easily understood. I highly recommend Pipe Wrench services."

Sasha N.

"Ryan and Tyler were fantastic! As soon as they got to our home they set expectations for all the work they were going to perform. They kept us posted on the status of the job throughout the time they were working and reviewed everything with us when the job was complete. They were professional, knowledgeable, and nice. I would highly recommend them and the team at Pipe Wrench for any plumbing needs! Although I hope we won't have to use their services again, if we ever have the need for a plumber in the future, they will be the first people we call!"

Katey M.

"They came on time with texts and calls ahead of time to ensure I knew who was coming (with a picture) and when they'd be there. Kyle was professional, personable and didn't try to sell me more than I needed. He worked with the scheduling to get me scheduled that evening, even though I couldn't be there for the install. The installation was prompt and they were clean (again with forewarning and pictures of who was coming). They are my new go to company. Thank you."

Mary W.

"Our technician showed up on time and very professional. This company never tried to take advantage of my older mom. Which some in the past have. Very thorough in explaining everything he did and the cost. They came the very next morning. My mom’s A/C had gone out the day before on a scorching hot day and week. I would highly recommend this company. Very good people."
