Personally, I would not want a sewer hose with a valve on the end, but that is my preference. No way would I ever want the possibility of a stinky slinky in need of ...........................
I do use a similar to valve above all the time to visually see the proper movement of waste water and I have in my sanitation tool box a cap for this. That would allow me the ability to really back flush clear water into any of the tanks from this valve. This may help if you have a buildup right behind the valve.
The valve I use does not have the flush adapter permanently attached. I did semi permanently attach just the gate valve and use a 45 degree clear adapter with the flush fitting. Basically the same as above but in two pieces.
Just another FYI, the black and gray tank drains are a "self cleaning blade type" device. Meaning that the actual valve is a thin 1.5" or 3" wide knife like blade that moves within a grooved portion of the housing. There are rubber seals on the blade and by keeping the blades open all the time there is a good chance of the rubber drying out a bit making blade movement difficult.
