Replacing damage black water waste valve

Thank you @LittleBoyBlue. Yours is not the first damaged valve mentioned here and I’m certain it won’t be the last. Very helpful information.

My black tank valve on my 2017 cs-s would not close completely recently. I ordered a replacement valve. I took the old valve out and could see nothing wrong with it so I cleaned and lubed it and now it works as good as new. New valve is in the spare parts box. Took just a couple of minutes to do this.

I cannot recall but vasoline kind of sticks in my head.

I also had a piece of truck tire wipe off the black tank valve on my tab 400 2019 on the interstate. I only noticed the damage when blue water gushed onto the road. By the time I stopped, i had dumped my tank on the highway. Got exact replacement from RV company (x2). Took a few hours to replace having to force the pipe sections apart and not push out the seal on the way in. I did use vaseline sparingly. Hopefully it lasts. My delayed winter project is to box in the pipe and valves for safety and to help prevent freezing.

Thank you for the link to the replacement part.
