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 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.

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.

Works ok but chatters when you try to fill up bowl with water. Original one didn't do this but occasionally leaked. Update, chattering stopped. Works great.

Didn't Last One Year!! Leaks water into the Bowl...
This looked like a bullet-proof replacement for the Dometic valve but just after 9 months in the trailer it is leaking water into the bowl and filling it up. The case has not broken and leaked onto the floor so that is good but it ended up doing the same thing the stock part did. Has a nice spring return and is built more solid than the original so I had high expectations.

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.

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.

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 :-(

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.
