Replacement Jacuzzi brand pump

treyragno · Oct 22, 2023

I have a 2018 Sundance Peyton hot tub.
It was out of service for several months due to a leak and finally got around to fixing it.

Upon fixing the leak I now have a noise pump. It is a single speed pump (Century 6500-352). I suspect the bearings are bad due to corrosion after sitting idle and empty.

Lesson learned. Find the leak and fix it to avoid this headache.

I have found Jacuzzi brand pump as well as some others such as LX and Hydromaster.

Are these LX and Hydromaster brands as equally good or even better? Cost is $300 for these brands vs $600 for Jacuzzi brand.

Let’s see what @RDspaguy thinks about those pumps.

Well, a rebuild is usually less than $150. Just my first thought.

Noise can be alot of things. I'd suggest you be certain it is what you suspect before buying anything. Unless your leak was the shaft seal of that pump, I have my doubts.
Many sundance pumps are proprietary, and built to certain specs not found in other brands. This is a fairly common practice. Be sure the new pump will work.
For example, one manufacturer made a motor at 22.5 degrees off level on the thru-bolts, then bolted an adapter ring to square it up again to then bolt to a wet-end using a different size bolt that nothing else fits. All to force you to buy marked-up parts from them. Sundance likes a 45 degree wet end, so make sure before you buy. I'm not sure what's in a 2018.

Ok. I am finally back home and got some more info from the pump and some photos.

The leak was from a LED light housing which has now been replaced and leak stopped. The pump doesn’t indicate any leaking.

I’ll work on getting a link to the awful noise it makes but sounds like rocks in a can. It does not appear to leak any water though. I ran it for an hour while cleaning the system with ahhsome.

How do I know which rebuild kit to buy? awful sound comes from the end closer to the pump. likely the bearings are shot?

Maybe it is. Check the impeller.

You don't buy a kit, you take it to an electric motor shop where they replace bearings, seal, and capacitor.

Maybe. Bad bearings usually make a grinding, growling, or squealing sound. Again, I'd be sure what it is before throwing money at it. Take it out and see what you find, or take it to a shop.
