Review: It fits my sunrise hot tub! - So far so good , I was happy to see it was the same exact fit as the original! It’s great knowing I can always count on desertcart to help me out with parts !
Review: Works in my Vita Spa - Fits perfectly in my Vita Spa waterfall valve. I would advise that you also purchase some Magic Lube (https://www.desertcart.com/Aladdin-Magic-Teflon-Lubribant-Sealant/dp/B006H3XBAU/) and smear it on prior to installation to reduce friction, otherwise the rubber piece will eventually become detached from the plastic body, which is probably why you are replacing this piece in the first place.

### ⭐⭐⭐⭐⭐ Works in my Vita Spa
*by S***D on 16 July 2023*

Fits perfectly in my Vita Spa waterfall valve. I would advise that you also purchase some Magic Lube (https://www.amazon.com/Aladdin-Magic-Teflon-Lubribant-Sealant/dp/B006H3XBAU/) and smear it on prior to installation to reduce friction, otherwise the rubber piece will eventually become detached from the plastic body, which is probably why you are replacing this piece in the first place.

### ⭐⭐⭐⭐⭐ Perfect fit for my Hot Tub/Spa
*by B***B on 6 January 2025*

The OEM parts are all plastic on the waterfall control valves and over time with the chemicals and heat they are pretty easy to over tighten and break. (See picture 2). This is the second one on my spa and this valve was a perfect fit for the replacement. The only thing missing from this kit is that you need two new "o" rings that go on the top of the valve to seal it to the plastic top that screws the assembly together. These are 1" in diameter. I also added some silicone grease to the gray/black half-round lower section of the valve that meets the opening in the valve housing to seal the water out. (See picture 1) This is a very easy repair once you have done one of these. A couple of tricks I learned. When I removed the black valve head and unscrewed the the valve body, the valve assembly slipped down into the spa. I inserted a pair of needle nose pliers into the valve body, opened them till they made contact with the body and then pulled up to raise the entire valve higher so I could attache the hold down head.
