I've been trying to research but can't find anything on it. I currently bought a house with a above ground pool. It has the lines to and from the pump under ground so there is caps on the pipes coming out of the ground. I found the pieces that screw into those but, is there suppose to be hardline (like pvc pipe) running up or just a soft hose going to the connections up top? Trying to see if they are around here somewhere but don't know what I'm looking for.
