Review: Was as good as the original and was easy to install and fixed the water leak.
Review: 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.

This is a product that either works or doesn't. In this case, it does. At this point, I can't see the difference between the OEM and this product other than price. This product works with my Dometic toilet in my travel trailer and was easily replaced. Essentially it's a hose clamp, screw, and then push clips on the product to remove, then reverse the steps. The hardest part for me was the access to the valve, which was very close to a wall. Most will not have this issue. Overall, I would recommend due to value. At this price point, I'm thinking of keeping a spare one since these are so inexpensive. As an RV'er, having spare parts on-hand prevents distractions from your trip.
