Hi,
My 3/4hp jacuzzi pump disintegrated during my shut down this year and I need to replace. I found a used 1/2hp Hayward Super Pump S4842N122A4 that I would like to install. Here are the specs on my pool:
Pool volume 10,000 gallons
Lift - approx 5 ft
Filter - Hayward Pro Series Model S-189T (Filter/backwash rate 23 gpm/sq ft, Design Flow Rate 40gpm, Max Working Pressure 50psi)
Heater - Hayward H1501
Will I be okay with the 1/2 hp motor? If not, can I install a bigger motor on the pump (Model 2600X5A)?
Thanks,
Wayne

You will be fine with the 1/2hp. The Hayward will move quite a bit of water as well. It may not move as much water as the 3/4hp but it's very close and the 1/2hp will cost a little less to operate so if anything, you may just have to run it for one additional hour per day to compensate. You will be surprised how much water a 1/2hp will move. The only issue with smaller pumps is if you have pop-up cleaner heads or a suction driven automatic cleaner such as a kreepy krauly, however, if a 3/4hp will run it, a 1/2hp will run it as well. You can install a larger motor on the super pump but it will not move more water unless you upgrade the impeller as well. Just make sure you don't use a bigger impeller than what the motor is rated for because it will strain the motor and cause it to overheat. Hope this helps.
Testimonial: "Great. Thanks for the quick feedback. I look forward to saving a few $'s this year operating my pool. Cheers!"
