Hot Tub 1 Inch On/Off Neck and Waterfall Valve Insert Compatible with Most Marquis Spa 350-6326

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.

Fits perfectly fine in our Freeflow Cascina. This has been a sore spot with a otherwise perfect hot tub. Counting the original, this is the third insert in 6 years. Seems like two years is the limit. The price was just right for this one.Called Freeflow and they deny having issues and can’t give me a reason why the rubber gate valve seal would detach from the valve.

Purchased this for my jacuzzi which has a waterfall and this product fixed the issue. I highly recommend this product.

Was not sure it would work for my Marquis spa, but it was a perfect fit and fixed the problem.

Fit perfectly in the waterfall diverter knob. The waterfall wouldn’t turn off and with jets on it would shoot all the way across the hot tub but after replacement, it shuts off and is more responsive to the knob. 4 stars because it didn’t come with o-rings.

I bought a Dr Wellness ho tub tub at the County fair a few years ago. About a year ago , the very top waterfall jets would not turn off . You Tubed how to fix it, and then did a search on Amazon for the part. It was the perfect replacement and so easy to install

Waterfall trickled when original valve was closed. This fixed the issue in about 5 minutes. Shut off tub, pop off valve handle, unscrew valve top. Swap this in for old one and all done. Waterfall no longer leaks when it shouldn't.

Used on a life smart spa. 1/3 the cost from other shops for the same thing.
