At the end of last season, my main pump (Pentair Superflo 1 speed 2HP) started to make a "clack clack" noise. My pool service guy told me that the motor needed to be changed at a cost of $350. The pump is only 3 seasons old (he's the one who installed it) and, although it runs 24/7 from May to October, I was expecting more life out of it. I can find the exact same pump on Amazon for $340 shipped, so I may as well get a brand new unit and sell the old one for a few bucks.
But do you guys think changing the whole motor or pump is overkill considering the pump still runs and does the job and a DIY rebuilt for much less is possible? I kn ow manufacturers and pool service companies tend to change instead of fixing ($$$). I see motor parts for this pump for sell, so could I just replace like the impeller or/and the diffuser and a few seals and be good to go for under $100. I know it might not be easy to diagnose the problem with just the "clack clack" sound, but I give it a try.
Thanks for the inputs.
