have a 2.5 hp motor now ,can i use a 4hp?
A shopper on Aug 14, 2020
can you wire this for one speed only?
Mike Z on Mar 22, 2021
BEST ANSWER: Sure can. There is a separate connection for high vs low. pick the one you want and leave the other empty. might want to try high and low to see which one you like. This pump is more powerful than what I took out so I rarely use high.
why no hose connection on the pump housing?
pershing l on Dec 20, 2021
BEST ANSWER: It comes with union nuts for hose connections
How do I measure the intake and discharge ID or OD?

water way pump
great motor and pump combo. exact replacement fit and performance as the original one. Had that one for 10 years. Hope to get the same from the new one. Would definitely recommend this pump for anyone with a hot tub/pool.

I had a difficult time finding the pump I needed until I found Pool Supply Unlimited. The spa pump selection on this site is unmatched. Not only did I find what I needed, but the price was great, the shipping was reasonable and the delivery was quick. I couldn't be more impressed. Thank you PSU!!
