Easier than I thought it would be
I thought this was going to be a complex operation, but it only took about 15 to 20 minutes to complete this so it is very simple. Everything fit correctly and it works delightfully after we got it in.

Works well but the included clamp is no good.
I was suspicious at first because the fit did not feel snug enough. Once I fastened with the supplied screw, it held firmly and works flawlessly. It’s been about a week and zero leaks. Zero issues. I will say the included worm screw clamp was not sufficient to hold the toilet fill hose firmly and I had a leak there. So I used a higher quality one from Home Depot that I had on hand and no issues. I would buy it again.

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.

Incredible Value
I put two of these in a brand new RV which was supposed to have been winterized by the dealer last year. Both had a crack in the same place. This part cost a small fraction of what that dealer wanted for his replacement. Easy install and works flawlessly.

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.

valve de toilette dometic
très deçu de ce produit qui selon les explications était supposément fabriqué avec des matériaux de haute qualités et double seal sur la tige qui controle le débit d'eau, mais quand je regarde je ne vois pas le double seal comme démontré dans leurs photos du produit . Ça coule par la tige quand on active la valve . J'avais confiance car il disait que ce produit était garanti à vie, mais la vie a pas été longue je l'ai retourné 1 heure après l'avoir reçu
