OK, I tried searching and reading through other posts because I am sure it has been covered but couldnt find it, and I hate to start another thread.
I have a 20k IG pool with spill over spa and waterfall. 1 1/2" plumbing to a pentair fns 60 DE filter. High electric rates here in San Diego, so looking to replace old single speed pump.
lots of good reviews for the IntelliFlo 011018 model 3 hp but requires 2" piping and 10" direct runs in and out. i can get it at a good price, about 850 plus a 200 dollar rebate from power company.
Now I find haywards SP2600VSP 1 1/2hp pump with 1 1/2" requirement in and out for about 650 but no rebate, so basically about the same price.
so long story short, I know I can downsize the piping from 2" to the 1 1/2" and I don't need 3hp, but would the pump last longer by being oversized? Or would I be better off matching the smaller pump to my need, since cost appears to be the same?
Thanks for all your help here.
