Quiet pump!

Replaced my pump from a 1991 hottub la spa model with this new pump and lay me tell you it is quiet. My only issue is that it didn't come with a grommet for the wire you hook up to it, either that or mine was just missing it? Still I gave it a 5star because it is a really nice pump.

Pump works great and way cheaper than OEM replacement

Pump was almost a perfect fit, had to make a few modifications to the equipment area. Pump lines up with the water lines perfectly and has been working great since install.

Great Price

I ordered a pump else ware and after not hearing anything for several days I tried unsuccessfully to reach them by email and telephone with no success. After about a week I finally got ahold of them and was told that the pump was on back order and would probably be another two weeks.
I called SpaDepot and had wonderful service and the pump was actually quite a bit cheaper and I had it two days later. They made my day.

Hope this one runs as well as the last ( an unbelievable 16yrs!). That’s probably too much to ask but everything’s fine so far. Thanks

6 star customer service

I purchased a balboa light pack from Spa Depot one year ago which has been working great. Recently, my old pump failed, and I replaced it with a brand new pump, purchased somewhere else. That brand new pump immediately popped breakers and blew a fuse in the Lite Pack. The place where I purchased that other pump would not answer the phone.

Remembering the excellent customer service I received when I purchased the spa pack, I contacted Spa Depot. Amie walked me through a diagnostic to figure out that that pump was faulty.

I purchased a second brand new pump at Spa Depot, hooked it up and it worked like a charm.
I have received consistent, expert service at Spa Depot. I would give them six stars if it was available!

Just had to rotate output to the side.
Runs great.

Old Reliable

Second of these, last one ran like a clock for 5 years and that's 24/7. Wanted the same reliability so we replaced with the same pump. Easy install, great product.

Great replacement pump

Great replacement pump for my 30 year old Sundance Hot tub. She is running like new again. I do think new gaskets should come with it however. We did have to purchase seperately to keep it from leaking. I hope we have many more good years enjoying our "dinosaur"... as my spa tech calls it. Thanks for always having the right parts and knowledgeable customer service.

New spa motor. Works grat

Ordered a new 2hp pump for my spa. Easy to install but didn’t seem to run right. Called their help department and the immediately told me I had it wired wrong. I thought my old pump was 220 but it was only 120. The tech was very knowledgeable and pasty and walked me through changing it over to 220. Works perfectly. Very happy with shipping quality and tech support. Also forgot to order an additional union flange , ordered it and it arrived the next day. Super service.

Great spa pump

This was an easy drop in replacement for my old 21-year-old pump. It’s heavy, and you need assistance to maneuver it into place but once again it works like a charm. You do need to buy one electrical accessory, such as a cable gland for the electrical connection but otherwise I’m very satisfied.

Not very durable

This is the second one I have replaced in 18 months. I would have opted for another brand but was this was the only 2-speed/ 2"" opening I could locate at the time.

Easy to install, works perfectly.

SpaDepot support helped me locate a replacement for a Flo-Master XP2. Installation was relatively simple and it's been working great for a week or so. Instructions are not great, but I took a photo of how the old one was setup and just copied the connections for the new one.

Complete restore of old spa

We recently bought a house that came with a 6 person spa that is 26 years old. It had all the original equipment, and it hadn't been working for at least 4 years. I replaced all the components (2 pumps, blower, ozonator, control box) and re-plumbed the spa all with parts from SpaDepot. We now have a perfectly usable spa with new equipment. I spent a fraction of what it would cost to replace the spa or hire someone to repair it.

I am a spatech and this product will be bought as needed.

Used for a spa.

Solid Replacement Motor

I used this to replace a single speed OEM pump in a Caldera Spa. It arrived quickly and securely packaged with foam surrounding both ends of the unit. It is about 2"" longer than the original with no provisions for hooking up the flexible cooling tube. Also the external capacitors add about 2"" to the width of the motor. The directions did not clearly show how to hook it up for single speed but the SpaDepot website did. It operates quietly and just as powerful as the original leaking and noisy unit did. I would recommend this part but be aware of the caveats mentioned above.
