Supply pipe
I am feeding two valves around my backyard. I live in a climate that has freezing temps all winter. Should I use poly pipe to feed these valves or use PVC? I heard that PVC will crack if the ground is heaved by frost even if the pipe has no water in it. How should I feed the valves? (100 ft away)
160 psi poly pipe is available for mainline situations but stubborn to work with and I've found that weak joint to be the connections at the fittings when used for a mainline
In Colorado, sch40 pvc is used in that situation. One must drain it properly thou, i.e. "blow-outs"
I'm sure commercial establishments in your area have plenty of pvc in the ground, so it will work just fine if taken care of.
Let me elaborate. I am in CT. So your saying if I go with PVC as a mainline to the valves (100 ft. away) buried 18", I will be okay provided the system is "blown out" in the Winter
you'd be fine, i wouldn't even bury it that deep. you'd be fine with 12"
you can also drain it on both ends without blowing it out in the winter.
I would use NSF-rated poly pipe. Depending on your water pressure, you could use 125 psi or 160 psi, and pull the pipe like for a sprinkler system. The heavier the pipe wall, the more difficult it is to clamp. The "Loxon" strap clamps made by Ideal are strong enough for this. There are also brass compression fittings for poly pipe, made for the waterworks market. They are as reliable as they are expensive.

I have a 150 gpm filter and a 10hp pump. I run a 4 inch main line. What is the biggest pipe size I can use with the Maxi Paws that shoot 40 feet? I am thinking of using 2 1/2 inch.
