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.

Works great. Love having a viewport on it so I can see when things are running clear.

Much better fit than other brand of valve which fell off while driving, and fit very loose and sloppy, this brand fits tight, no leaks, very good product, Camco products are top notch.

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 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.

Perfect...2020 Montana 3811MS... Exactly what we needed 👍 Holds back All the stuff that vibrates loose during transport. Prevents that nasty surprise when you pull off the cap.

This is a great piece to add onto your dump valve. Extra protection from accidentally having a bad day. The clear view is also nice to help see if there is anything behind it before taking off you hose

Prevents any leaks that can contaminate your campsite. This is my second one as I bought a new trailer so I left the old one on the past trailer. Excellent product for a low cost

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.

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

One grey water tank value is not working so this was the most convenient and inexpensive option. I don’t leave it on while travelling as it sticks out a few inches plus others commented on them coming loose and falling off while travelling. I put it in when I set up and remove it after I empty the tanks. It is very easy to take on and off.
