I just looked up the domestic 310 parts on google and got to the domestic parts list. Went from there. Good luck. Oh and it's easy to replace, even in place. The prongs are stiff but will release eventually. **Q: With this new part I do not have any leaks but a few times when you go flush I get no water. I have to turn the water on& off at the sink to flush...?** A: Mine did the same thing. When I installed the valve I didn't put the screw in to hold the valve in place. After I put the screw in I had no more problems. I get water in the bowl with every flush. **Q: What is the size of the thread?** A: There is no thread size for this valve. The supply line is clamped on. This is a valve for the toilet. **Q: I replaced mine due to a freeze issue and the new one will not shut off. Has there been problems with the end of the push in valve sticking?** A: My valve had an issue sticking open where I could not stop the water flow. Had to remove valve, sprayed WD-40 inside valve, valve doesn’t stick any longer. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect *by on Reviewed in Canada 27 June 2023* Very simple to install. Perfect fit. Easy DIY project. Works perfectly ### ⭐⭐⭐⭐⭐ This one works!! *by on Reviewed in the United States 14 July 2026* This one worked!! I originally ordered the knock off “improved design” one sold under the name Beech Lane WHICH FAILED RIGHT AFTER INSTALLATION!! It ever so slightly leaked water into the bowl which would have eventually flooded my travel trailer.Please order this OEM part like I wish I had done! It actually works when you install it. ### ⭐⭐⭐⭐⭐ Efficacité *by on Reviewed in Canada 12 June 2024* On a essayé un autre moins cher, mais n'a pas fonctionné. Ça vaut la peine de payer pour l'original. Rapide à réparer et efficace. ## Frequently Bought Together - Dometic 385311641 Genuine OEM Water Valve Kit | 300 301 310 320 Dometic and Sealand Toilets | Includes Hose Clamp and Fasteners | White Compact Kit for Efficient Repair and Replacement - Dometic 385311658 OEM Flush Ball Seal Kit | for Use with 300/301 / 310 Series Toilets - Dometic 385311652 Toilet Base Seal & Mounting Hardware Kit, White | 300 Series Toilets | Genuine OEM Spare Part --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/137226114-dometic-385311641-sealand-water-valve-kit](https://www.desertcart.sk/products/137226114-dometic-385311641-sealand-water-valve-kit) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-14*
