Curious who's done this on their own? I'm handy. I do my own electrical and plumbing for the most part (Until I KNOW I'm going to be over my head.) Looking over the install manuals for some HP and they don't look too bad. The pad is already poured and the electric service is already at the pad for the HP. It's not so much the cost, it's that I enjoy doing these things myself. But since I've never installed a pool HP before, I don't want to make a mess of it. Seems simple enough, but. . .
