I have a residential customer with an in-ground, 35,000 gallon vinyl lined pool. They have an older Outdoor Pro wet end connected to a single speed RECHAMPS--115 1.5 HP motor (US Motors 1081 POOL MOTOR). The thing is making a lot of noise and the flow has plummeted to nearly nothing. As the whole thing is old and the customer is 30 miles out in the woods, I am inclined to just replace the whole thing but with what? Pricing is all over the place from a few hundred to a few thousand dollars. I have recently had some bad experiences on the commercial side with Pentair weaseling out of their warranties and am done with that brand. The customer is a disabled vet and a hospice nurse. They are not rolling in money. What should I buy them?
