Review: Dometic 310 - This works great so far (installed it yesterday). It was a perfect replacement on my Dometic 310. I didn't even have to take up the toilet. It took two small screw drivers to push in the clips to remove the old one, but the installation of the new one was easy.
Review: 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.

### ⭐⭐⭐⭐⭐ Two Screws Hold it to the back of the toilet!
*by J***. on May 29, 2024*

This was the First Time replacing the foot flush water valve. I removed the toilet and ordered this replacement. It was easy to install. Seems to have more flush pressure! I went a few steps further and added a valve to my pex behind the toilet ! I did this for a friend's camper last winter and since mine was leaking went ahead and bought another shark bite push on valve for my camper so if this happens again I will be able to Just turn off the toilet water and use a Bucket to flush the water instead of water ruining my camper floor if it leaks again! Now I am able to make 100% sure the toilet doesn't leak when I am gone. Now I don't have to yell outside to turn the water off or run to the outside faucet while water is all over the floor. Saves on Towels too. Valve was less than $20 at Lowes Home Improvement. Don't cut the pex too short. Grab the pex with Visegrips before you cut it or you will be fishing the pex out of the hole in the floor. That's no fun.
