Just a side note, You cannot see in the pic where my PEX lines exit my pump house, but I laid 4" sch 40 PVC from the pump house into the water so that the PEX line would be protected. I have ALOT of rock. This also allows me to push another PEX line through in the future or replace a line if need be. I could even run two more lines and add a pump to the house that could operate a fountain. My pump house is only 30 feet from the water's edge.
