(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. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/333778844-hot-tub-classic-parts-1-inch-on-off-neck-waterfall](https://www.desertcart.vn/products/333778844-hot-tub-classic-parts-1-inch-on-off-neck-waterfall) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-06*
