I'm hoping there is still something I can do, but it's Wisconsin and the temperatures have already reached 5F
It is 35 today, but will dip back down again.
Anyway - the system is all Rainbird and the piping is 1" poly. There is a shutoff in the basement to the irrigation system and that goes out to the blowout and out to the system.
I recall when they installed that the poly wasn't as deep as I would have wanted. I'm guessing 18" below the surface, but it went down rather gradually from the valves (which were probably 8"-10" deep).
There is snow cover (about 6-8") and no easy way to get to the sprinkler heads. I'm sure I could dig out to the valve boxes as they are close to the house and under less snow. shouldn't be too hard to find.
I think that's all the information I can give... hope there is some help for me. The people that installed my sprinkler just said there is nothing I can do - but I refuse to believe that.
