Camco Camper/RV Gate Valve - Features Built-In 3.5-Inch Clear Adapter & 4 Bayonet Prongs - Fits 3-Inch Sewer Fittings & Connects Easily to RV Drain Pipe (39053)

I used this Camco RV gate valve in combination with their black tank rinser wand while cleaning out our black tank, and the results were excellent. Together, they allowed for a controlled, thorough flush that completely removed buildup and fully restored accurate tank sensor readings. Being able to see what’s happening through the built-in clear adapter adds confidence and takes the guesswork out of the process. The valve installs easily, seals well, and the four bayonet prongs create a secure connection. It’s now part of our regular tank maintenance routine after every camping trip for both black and gray tanks. This is a well-designed, practical tool that makes proper flushing easier and more effective. I highly recommend it to all RV owners who want to maintain their tanks correctly and avoid sensor issues.

Needed this very much. I like being able to see if there is going to be a surprise of "water" when I remove the cap. It helped us because of a leaking valve on our system. It was repaired but we still use this for peace of mind. Works great and easy to install. It really is nice quality and looks to be heavy duty.

This has saved me already. I thought my black water tank was empty but I just wasn’t level. I was able to see that I accidentally left my valve open and I was able to avoid getting black water all over me. Fast forward my friend calls me and this exact scenario happened to him. The functionality of this is perfect, the construction of it is strong, and the plastic material feels thick and able to resist any dings it may get on the road. Installation was easy with the instructions.

This works great as a secondary valve and I like the clear connector so I can see if the tanks are draining

Works great. Our 5th wheel has a good section of dump pipe after the valves leading to it always a mess when I took off the cap. This solved it.

This thing is a lifesaver. My original drain has been leaking some after a few days, and I was not looking forward to taking the pipes apart to install a new cut off. This just attached to the existing holder and works wonderfully. It does not extend past the side of the trailer, so I don't have to worry about it getting knocked off.

Absolutely an outstanding purchase. A few weeks ago, I was surprised with a gallon or two of stinky stuff when I removed the outlet cap. I didn't find anything leaking, but obviously it had. With the clear pipe on the upstream side of the valve, you can tell if their is a leak, but it also allows you to hook up to your dump hose without being exposed to waste. On my trailer, it does protrude a bit, but I do not consider that an issue.

This makes things SO much easier if you ever have to use a portable tank to dump. Hoghly reccomend!

This is a good product made with decent parts. The clear viewing tube lets you see what is happening inside the pipe, which helps you know how clean you have flushed your tanks, or if you need to do another rinse. It provides a third valve to catch any liquid that may leak past your grey or black valves. The small area in front of the valve only holds a small volume of liquid, so if this valve should leak the mess is small when you open the cover. The cover snaps on well and seems to be made of a tough nylon material, giving a solid feel to the locking hooks. On my rig the sewer outlet is in too far from the side of the trailer, so this brings the hose out to a easier location to deal with. Super item!

After years of terrible troubles with the valves in my trailer, this has been a godsend. Absolutely wonderful. The little clear plastic section allows me to view if there’s any product on the other side of the valve. The valve seals perfectly not a drop. I leave my sewage and gray water fully open now and I exclusively use this. I almost never leave reviews, but this is great.

Vraiment très utile, résistant et facile à utiliser.

Connects fine without any leaks. One advertised picture showed it having a wash back connection but not so. Overall, happy with it

Works as advertised.
