Hi, We intend installing a ground loop/slinky on our property. The loop may need to be above where the house sits (ie house is lower on slope). Generally what restrictions are there on loops being higher (or lower) than the pump and does the excavated trench need to be level or can it slope? I assume if not on level, there is more effort required for the ground circuit pump.
Elevation change and levelness of trench have no bearing on the pumping power needed. What ever extra you use pushing water up the hill, you get back when the water comes down the hill.
We drill Think about vertical loops...level not required. Your installer should have these basics covered
