After completion, our horizon pool was great, except for the fact that when water was pumped out of the trough there was not enough volume to bring the pool water level up to start the overflow!!!!!!
The pool contractor "solved" this problem by adding a 800 gal or so tank under and next to the trough, this seemed to solve the problem, but on many occasions I had to prime the pump to get the water pumping. I made this easier by tapping into the suction line and adding a valve to the backyard water supply. Now after a few years this "priming" is becoming more and more frequent. I believe the pump is probably due for replacement. Since the equipment is 50ft from the pool and the tank is buried some 8 ft below ground, what pump should I purchase for replacement? This pump only runs the water from the trough and tank, the pool circulation is done by another pump.
