    Black tank gate valve - slow leak

    Need to get a gate valve repair kit for my black tank (it HAD to be the black tank! -UGH). From what I've read, they're pretty universal. Doe anyone have a good part number for the repair kit? Thanks.

    Depending which valve is installed, you might want to reconsider replacing the whole valve. Mine came with LaSalle Bristol valves and the cable cant be replaced without the taking the valve out. I replaced two of my valves with Valterra valves. Not to mention GD does less than stellar in routing the valve cables.

    Replacing the valve is the same work as replacing the seal rings with the exception of routing the pull cable. The flanges for both are interchangeable.

    If you already have Valterra valves all you need to purchase is the blade seals, it is 2 rubber sealing surfaces, not sure if it comes with 4 new nuts and bolts or not. Any RV store should carry these, black tank valves are 3" valves.

    Thanks. That’s exactly what I was considering but thought I’d ask first.

    Is this the one?

    That one will work, just make sure the cable length is correct, it is offered in different sizes. I've read you can cut to shorten, but I didnt need to so I dont have any experience with that part of the install.

    I had and have the same issue and GD sent me a new Valterra but I leaks so I took it apart and found some abs glue obstructing the seals so I cleaned it up and now I am waiting to see if it still leaks. I bought my seal off amazon for around $7

    Check to be sure but according to the GD parts lookup you need a 96" cable. I ordered one for my 337 from https://www.rvupgradestore.com/Valte...-p/71-5523.htm

    Confirmed mine is a 72" cable.
