Beech Lane Upgraded Water Valve Kit Replaces 385311641 for Dometic Toilets 300, 310, and 320, Increased Freeze Resistance, Long Valve Lifespan, Ultrasonic Sealing Safeguards Against Leaks (Natural)

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.

Perfect fit - works just like it should !!!

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.

Just go ahead and change the quantity to two or three right off the bat. I purchased one to replace the original OEM and it only lasted a few trips. I purchased two the second time I purchased and was glad to have a spare when the second one failed less than a year later. It’s nice they are cheap, and fairly easy to install. Our camper didn’t have a shut off valve for the toilet, so I learned another valuable lesson and i stalled one of those last time as well. I now will keep an extra water valve on hand at all times and I recommend you do the same. The OEM ones for a lot more aren’t any better so may as well buy a couple cheap ones like this.

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.

As someone who hates DIY repairs, especially when it comes to my RV toilet, I can say this Beech Lane replacement valve made the process a lot less frustrating. It’s designed to fit Dometic 300, 310, and 320 series toilets, replacing part 385311641, which is great if you're tired of leaks or yearly valve replacements. 🔹 Why I Chose This Valve: ✅ Freeze-Resistant Technology – This was the biggest selling point for me. My original valve cracked after a hard freeze, leaving me with a leaking toilet and a major headache. This valve’s glass fiber reinforced polymer construction is designed to withstand freezing temperatures, making it far more reliable in cold weather. ✅ Over-Engineered for Durability – This valve feels solid and better built than the original. It’s designed for longevity, so I’m hopeful I won’t have to replace it anytime soon. ✅ Rotary Seam Melting – The seams are completely sealed during production, which helps prevent leaks. This is a small but important detail that makes a difference in long-term performance. ⚠️ Minor Drawbacks: ❌ Tight Space Installation – Like any RV toilet repair, installation wasn’t fun. The space is cramped, and working at awkward angles is inevitable. However, this isn't the product's fault—just the reality of RV maintenance. ✅ Final Verdict: If you’re tired of dealing with leaking RV toilet valves, especially after cold weather, this Beech Lane upgrade is worth it. It’s built to last, and the freeze-resistant design gives me peace of mind that I won’t be dealing with another cracked valve anytime soon.

If you have a toilet in your RV camper that is leaking water at the foot pedal there is a pretty good chance the valve is leaking. This 20 dollar part could fix your problem. Don’t call some mobile RV repair gypsy that’ll tell you that you need a new toilet and it’ll be 350 dollars. Don’t drag it to the dealership and try to fight for a warranty repair. It’s only 2 screws and 2 water connections. You can do it yourself. I promise. Just make sure your water supply is off before you start. 20 minutes later you’ll be up and running with no leaks. This product is exactly what you need with better than original quality for a great price. This replacement seems to be an improved design over the factory toilet valve. I bought this product based on the perceived quality in the images. And it did not disappoint.

Part seems well built, onky time and use will be the true judge. One thing I dont like is the company pastes American flags and says they are a proud US based company wanting you to think they make parts hwre, they dont. Valve had a large Made in China sticker so if you care about those things thwn it might matter ro you.
