RV Toilet Valve Fix That Packs a Punch!
I’m really pleased with this water valve kit for my RV toilet! It was a perfect fit for my Dometic 310, snapping right into place and stopping a pesky leak in no time. Installation was quick—under 10 minutes with just a screwdriver, thanks to the included hose clamp, screws, and clear instructions. The sturdy ABS plastic and stainless mesh filters feel high-quality, and it’s been working flawlessly with no drips or issues for weeks. It’s a compact, affordable solution that’s a must-have for any RV camper. Saved me a ton of hassle and kept my trips worry-free

Glad to have an extra valve to carry because we ...
Rating is for the valve, not the Dometic toilet! Fits the 310 toilet, although what arrives is a bit different from the photo. Called Dometic and they've redesigned it to make the clips easier to install and the valve stronger. Hopefully won't be as susceptible to freeze damage. Overall it's a design flaw in Dometic toilets that this valve fails if even half a drop of water is left in the lines without antifreeze (blowing lines is insufficient with this toilet) if temperatures barely freeze. Glad to have an extra valve to carry because we fully expect another valve failure.

Seems to work well
This fit my Dometic 311 RV toilet. Upon first install, I experienced a slight dribble of water running into the bowl while under pressure. I didn't think of it until I was no longer on a water supple, but I thought perhaps I had inserted and over tightened the valve into its socket causing the nipple feed to pressure up against the flush pedal. I've backed off the screws a bit and will see what happens next time I'm connected to a water supply. In any event, the amount of water dribbling into the bowl will take a long long time to cause concern. I suggest that if you need to replace this valve, install a shutoff for water coming in if you don't one already installed. Also, change all the seals while you're at it. Happy going.

Easy-peasy replacement, except for space constraints
My toilet began leaking near the foot pedal. I called Dometic and they recommended replacing this valve. They would charge $75 plus shipping. So this was a much better deal. It’s an easy replacement at first blush. But my toilet was close to the wall in the WC and it was difficult to get hands and tools in the right places. So, what would have been a 5-minute job (if there was more space around the toilet) became a 60-minute job. But none of the abovr the fault of the part. The replacement works great No more leak.

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.

Good price for the valve but the problem was the peddle bunched a hole in the peddle cam causing the peddle to jam and no water to flow. Dometic has serious problem design on 310 toilets. The peddle cam design has no strength in the material and Dometic doesn't offer a replacement part, just new toilet., this model has a serious problem.

We had to replace the flush valve on our Dometic 300 toilet as the existing flush valve was leaking this spring when I pulled it out. I was going to replace it with an after market brand that was cheaper, but decided to go with the OEM one instead just to be sure I didn’t have any unexpected issues. Glad I did...perfect fit, very solid and firm fit in the valve “holder” and the clips are firm plastic. Watered up, and everything held without leaking. Very happy! Now to take the toilet apart are reseal the other gaskets to ensure I don’t get the dreaded Dometic 300 stench....

My local RV dealer wanted $90 for this part, so I feel here it is good value. Having said that, when I inquired about the failure of the valve I was told it is a common problem and that no changes to the construction have been made, so we shall see how long it lasts.
