Anyone use the compression fittings for PE loop pipe available from geohydrosupply? I'm planning on constructing my own PVC pipe loop manifold in the basement next to my geothermal unit. The 3 vertical well loops of 3/4" HDPE pipe would terminate to the PVC pipe manifold via isolation valves. I was originally going to use steel or brass barb type insert fittings to connect to the HDPE pipe but I found these plastic compression fittings for connecting 3/4" PE pipe to 3/4" PVC that thought that might be the better way to go. Just trying to get some input on any actual field experience with these fittings.
