Protecting your Backflow Prevention Device from a Freeze

Home / Uncategorized / Protecting your Backflow Prevention Device from a Freeze

One of the most costly components of a sprinkler system to replace is the Backflow prevention device. And it is also the most vulnerable in a freeze. Let’s say that an early freeze hits the Denver/Boulder area before you get a chance to blow out your sprinkler system. Repairs for a Backflow prevention device (BFP) can run you anywhere from $200-$400. If you need a simple solution, wrapping the BFP with something as simple as a paper bag can prevent this kind of damage.

The BFP is usually located  outside the home and close to the foundation and is clearly visible above ground. In order to properly protect it, you need to wrap it with a towel or some sort of household insulation, then cover the towel with a sturdy plastic garbage bag and secure it around the bottom with duct tape. As a result of taking this precaution, your BFP will stay dry and protected if there’s a freeze before the system is winterized.

But don’t let that be the only thing you do! In Colorado you still must winterize the entire sprinkler system by blowing out the lines with compressed air. Lifescape Associates can winterize your sprinkler system and have it ready to go come freeze, sleet or snow. Just give us a call at 303-831-8310.
