My Power-Flo LX 40gpm pump needs replacing. The seals are failing due to running chlorine pucks through skimmer & also shearing off a screw on pump housing whilst trying to open it up for replacing parts. (Newbie mistakes!)
Should I buy
1. Same model pump again, using old pump for spare parts?
Hayward SP1540C Power-Flo LX Series 40 GPM - $187
2. More efficient (?) single speed pump like this?
Hayward Power-Flo Matrix 3/4 HP - $148
3. Or a more expensive 2-speed pump?
Hayward SP15932S Power-Flo Matrix 1-1/2 HP 2-Speed - $290
Or a different 2-speed like the Pentair Dynamo? My electricity costs in Northern NJ are only $0.11/KWh.
Thanks in advance!
