A Necessary Reliability Upgrade for Dometic Toilets
I picked up the Beech Lane Upgraded Water Valve to replace the stock valve on my Dometic, and the value for money is immediately apparent. Dealing with a leaking toilet in a travel trailer is a nightmare, and this kit is a high-quality solution at a very fair price. The quality of this valve feels great to the original equipment; the plastic is sturdy and the internal seals appear robust. In terms of Size, it is a perfect direct-fit replacement for the 385311641 part, meaning there were no issues with it fitting into the tight housing on the 310 series. It provides a crisp, clean flush with a strong water flow and, most importantly, a tight shut-off. Minimal tools needed. i am a mechanic by trade so i did not see anything overly complicated to the replacement.

Full time living w/no leak!
After the original flush valve epically failed (it stuck & I woke at 3am w/2” water on the floor) I paid $7 for a replacement. Made in China. It leaked down the side to the floor screw, & around the toilet. We put a towel, every 4 days. Got another, $12. Made in China. It leaked worse. Same problems-change the towel daily. I went with this American company, and my heart sunk when I flipped the valve over: “Made in China”. Well; it has a lifetime warranty… Third time was the charm! Working properly, no leaks. It’s been some weeks, now. I’m starting to trust it. The toilet saga has taken 10 months, but I think it’s finally over. Thank you!

Great product. Works fantasxtic.
Great product. I changed out the toilet three times and used other brands. They all leaked. This valve seemed heavier and fit great. Most importantly no leaks. Highly recommend this Beech Lane product. The other valves were cheaper but if they do not work and leak. They sure are not cheaper. This does not cost that much.

Exactly what I needed
This is exactly what I needed to fix the leak in my rv toilet. Unfortunately I have to replace it every year after winter but I’m glad it’s an easy thing to replace and it’s not expensive.

Great factory replacement
We had to replace our faulty toilet valve for our RV and was looking for a replacement that looks and functions like factory original. The Item come with everything needed to replace your old one. After installation, which was a breeze, we tested it and it worked like new. ,I would highly recomment this product to anyone!

Great product
It works as described, easy to install. I didn't get my holiday trailer winterizes before our first freeze up. The trailer froze solid. All my lines, freshwater tank and toilet. The valve did not brake like the original one. Great quality. Highly recommend if you live where the weather freezes.

Perfect fit
This unit replaced the existing one because it had a leak caused by freezing (second time I’ve had to replace this). I will winterize the trailer soon and will find out if this one will survive the winter. The unit did fit and worked perfectly.

Décevante comme valve
Après avoir vu les vidéos. Je m'attendais à avoir une Nec plus ultra de valve. Au final elle fuit l'eau plus que la précédente (Pièce d'origine). Moi qui croyais payer plus cher pour une pièce 'made in USA' et recevoir une made in China :-(

Valve d'eau modèle 310 pour toilette Dometic
Je ne peux pas évaluer la fiabilité du produit pour le moment! Cependant, j'ai payé vraiment moins cher que chez les concessionnaires de VR. Le produit a été facile à installer. L'ensemble contenait tout les éléments pour une installation complète. Après vérification avec la pression d'eau, la valve faisait le travail, sans égouttement! Maintenant reste à vérifier la fiabilité du produit.
