Hello. Last year we had our 24' Radiant Metric pool installed by the only pool company in our area who is authorized to sell/install them. Overall it was a great experience, but on the support side of things these guys are awful. Anyway, it seems as though they installed the cheapest pump they could. It's a single speed Hayward SP5715W, and may be part of a kit Radiant sells the pool with.
A couple of problems with the pump;
1.) Its pretty loud.
2.) When I set it on an external timer, so that it comes on at certain times, I've come home from work to find the pump running empty. It seems as though it needs to be manually primed before coming on (?)...which throws the timer idea out the window.
3.) It's expensive to run. When we first had the pool installed, we ran the pump 24hrs a day, and it was adding over $100 per month to our electricity bill.
The pump is about 35' from the intake/return, and is slightly elevated compared to the skimmer (maybe 2' higher than the skimmer). Can you recommend a decent replacement pump, likely a two (or variable) speed that won't cost my first born, is energy efficient, and would be an easy swap out for me? I think the pool holds about 12,500 gallons of water, it's round and partially buried in the ground.
