You can also backflush it with no tools needed.
Empty black tank, leave valve open.
Cap the outlet.
Open gray tank valve. Gray will flow backwards into black tank piping.

Mine became an issue a few years back - this is what I found in my gray valve:

They are easy to disassemble, but I hear ya - age has a way of limiting your abilities. Get the grandchild out there to help - they clean up pretty well!

I also have a TC and had the same issue only with the gray tank. to change the valve would have been a huge job so the add on valve worked great.The added few inches has never been a problem.

I bought an add-on valve and installed it. Thanks for the tips on it. Didn't know they existed! [emoticon]
