Backflow Prevention Testing Services in Denver, CO

Denver's Backflow Prevention Experts

When water flows down your drains, it’s easy to forget that it relies on a critical balance of pressure to keep it flowing smoothly. If there’s back pressure or siphonage, wastewater can suddenly flow in the opposite direction– causing a host of unwanted problems! To prevent this from happening in your home or business, contact the professionals at Cooper Heating and Cooling. We offer comprehensive backflow prevention services throughout the Denver metro area, all backed by the 5-star reputation we’re known around town for. So, for fast scheduling, honest prices, and trusted workmanship, call us today!

Backflow prevention cost factors:

  • Diagnostic fee: If you smell sulfur-like odors, notice discolored water, or your drains seem to take longer to clear, you may have a backflow issue that needs attention. Contact the Cooper Green Team today, and we’ll get to the bottom of it. For our time and labor, we charge a $119 diagnostic fee. If you need help after 4 PM on weekdays, this fee is $219; on holidays, it’s $328.

  • New installation: If you don’t have any backflow prevention in place, we’ll need to install a backflow preventer device that stops potentially hazardous wastewater from contaminating your home. We can also install check valves that detect sudden changes in pressure, so you’re alerted to problems as soon as possible.

  • Repairs and maintenance: Backflow preventers must be repaired and maintained periodically like the rest of your home’s appliances and systems. Depending on the problem at hand, your costs will vary. However, you can always count on us for honest pricing and advice that serves your best interest only.

"... excellent service from a very knowledgeable technician... I couldn't ask for more."

My system was not humidifying. I received excellent service from a very knowledgeable technician. He was quick, had a replacement valve on hand and was happy to keep me informed of what was going on as he worked. I couldn’t ask for more.
