Backflow Preventer Insulated Pouch (5F) - Pressure Vacuum Breaker Cover - Winter Water Well Pump and Sprinkler Valve Insulation - Protects From Severe Snow and Intense Sun

While the cover is not a perfect fit for my backflow preventer it still fits and looks very nice. It keeps the brass staying nice looking and helps keep the warmth in when the temperature gets low. It is very easy to install, and it covers the entire backflow preventer. It has been outside for almost 2 years and has held up very good. It is thick and is definitely worth the money to save your backflow preventer from corrosion and the element elements.

I recently bought this for protection against intermittent below freezing temps at my house. Outdoor plumbing it a thing in the Southwest states of the USA. But sometimes we have bouts of cold that require insulating things to protect them from cold. This perfectly fit my 3/4" pipe Pressure Reducing Valve that feeds my house from the water meter outside. I do not know if it would work in extremely cold areas, but it works fine for my needs. It is built well, fairly thick insulation and fabric, as well as good quality "Hook & Loop" fastening strips along the inner edges. Well worth the purchase price.

Worked great! No frozen pipes.

The only problem is that I had to cut the pouch to fit over my water filter. I have a water filter on out side of the house that needed insulating. In TX so it does not get real cold but some times it gets at freezing. I taped the cut edges with alum tape to keep the insulation in side dry.

I was sick of wrapping my large well pipes every year with insulation wrap. I thought I would give these a try and so happy i did! They seem like they are made out of quality material with several layers of protection. They were easy to install and fit perfectly! Now we will see if they will hold up to the freezes!

Had this thing wrapped around my back pressure valve in less than 5min. Every year my valve bust even if draining it, so finally said screw it and insulated it. Been installed a week and still looks brand new. Seems like it’s durable enough last a few winters or more.

Check your sprinkler setup 1st to get right size but this is a very nice, thick cover and came with zip ties to secure from wind and theft. Absolutely get one. Less trouble than wrapping.

Item just as described. Very nicely made. Fit perfectly
