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)

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

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.

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!

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.
