Our drain valve broke and this replacement fit perfectly!!! I think we like this one better than the one that came with our RV.

This is an ok drain valve for our camper's fresh water tank, but I was a little disappointed. The plastic is very soft so I'm afraid it won't last long. The drain hole in the rotating part is surprisingly small considering the 1/2" diameter threaded inlet...it will take a while to drain the 30 gallon tank. Finally, I had intended to clamp a short piece of hose to the barbed outlet to make it easier to drain, but was surprised to learn that the entire barbed outlet rotates with the handle. This means that any hose we clamp to the outlet must be able to turn 45 degrees in order to operate the valve. It also means that if the hose rotates while going down the road, the valve will open with it and all of the water will drain out. So, I'm back to just draining the tank on the ground. I guess I assumed that it would work like a brass ball valve, where all of the rotation is inside the unit and the outside is fixed.

Our dump valve on our popup camper water tank was getting very hard to open and close, I was concerned the handle would snap right off. So I replaced it with this, and it was a perfect fix.

Great replacement valve for my tent trailer water tank. Old one disintegrated, this one simply screwed in and worked fine.

Needed a shut off valve replacement for my RV water holding tank. This simply screws into the existing fitting. Installed in seconds. Holds tight. Well made.

I needed a 3/8 in male pipe thread valve with a nut to secure it as a bulkhead fitting. Dual 3/8 and 1/2" threads on valve worked great

Sigh... Purchased May 2018. Very lightly used; two trips since then and already dripping out of the valve. It's not so much the money, it's a pain to remove/install the drain valve on the trailer.EDIT July 2021: On a hunch, I applied some silicone faucet grease to the interior of the valve. This seems to have completely stopped the slow drip from the valve.I first applied the grease to the end of a q-tip. Then inserted it into the closed valve such that the blob of grease would go through the hole in the valve's rotating internal cylinder, and get smeared on the fixed outer cylinder. Then operated the valve a few times to spread it around. Be sure to use silicone faucet grease (aka plumber's grease) that's safe for potable water systems.Changing from 2 to 4 stars.

Pretty simple replacement device that works great. For my installation, it was as simple as unscrewing the old drain valve and screwing this one in its place. No tape dope and don't over tighten. I also had to cut the 3/8" nub off since my tank had a 1/2" connection. When I did this, I first opened the valve all the way, then I placed the 3/8"threads in the rubber jaws of my vise. Be gentle with it. I then sawed it off so that the shavings would fall down and not into the valve. I then blew reverse through the valve just to make sure there were no shavings and I also inspected it before turning it the first time. For all of the negative reviews stating that this product leaked from the valve, not the threads, I think at least some of those people got plastic shavings in the valve when they cut off the 3/8" nub and then turned the valve and lodged shavings in between the plastic, thus causing a leak. Also, this is NOT FOR A PRESSURIZED LINE. This is a drain tank valve. Don't attached it to a pressurized line and then complain that the product sucks.
