Fall is almost here and quite shortly Jack Frost will be traveling all-around making things cold! He loves to target irrigation components!
All it takes is a little little bit of icy cold to freeze up these backflow prevention components. If you've ever opened one up they are full of seals, o-rings, gaskets and little springs and orifices that just beg for freeze damage. When water sits stationary inside and is frozen by the surrounding metal it expands and does all sorts of bad things to the internal parts.
This problem with pipes freeze makes irrigation insulation extremely important. A backflow insulation blanket adds r-value to the backflow and helps to trap in heat. They also provide wind protection which is extremely important. So if you haven't put polar parkas on your weekend shopping list you might want to!
