Can I use pool noodles, towels, pillows, etc. as irrigation pipe insulation?
No, the best way to prevent your pipes from freezing is an insulated foam pipe like our Thermacel seam-seal foam pipe. Thermacel has a low thermal conductivity and low water vapor transmission rate making it the most effective when it comes to protecting your pipes and irrigation system.
Should I close the backflow ball valves during a freeze?
No, normally you want to keep the backflow ball valves open since they tend to retain water as well. When you start winterizing your backflow preventer, it's important to note to insulate all the way up to the ball valve and cover any exposed parts. If the backflow ball valve is closed and the water freezes from the inside, it can crack causing you to replace the valve.
How do I know what size backflow preventer insulation pouches I need?
The first number is the length and the second number is the height. To measure the length, take a measuring tape and start halfway around the elbow and go all the way out to the test valve. Add a few inches so the pouch can sit comfortably. For the height, it's important to cover all of the PVB. Start your measurements from the top of the bell to the bottom of the device. Note, the measurements listed online are that of the pouch, not the backflow device.
