Hi all, I don't post much on here but lurk and use it as a resource when I'm having issues. Hopefully you all can help with this one.
I have a ~15K gallon SWG pool with three waterfall features (two about 18" above pool surface and one ~28" above), Pentair cartridge CCP520 filter (150gpm) Whisperflow WFE4 pump with a 1.65 SFHP pentair motor.
Lately the top water fall isn't working. Water just kind of dribbles out. I've made sure the filter was clean. Baskets are clean etc. I even took apart the wetside of the pump to make sure all was well. I'm assuming at this point the motor is on it's last leg. I was looking into replacement motors and wondering if I shouldn't try a higher HP motor as the top waterfall has always seemed weak (it's the first to show signs of even a slightly dirty filter). Pool Supply Unlimited shows a Magnetek full rate 1.5 HP 1.5 SF (so 2.25 total HP) replacement motor when looking up my OEM part #. Would this be a good motor to get to try and get a little more stable action from my top waterfall or am I going to exceed my piping/filter or rating on something else?
