And no, I didn't have this on my "to do" list that I posted earlier this month. Even though I knew it had to be done.
For those of you who aren't RV'ers, I'll explain. There are sliding blade valves that you pull, in order to dump the black (toilet sewage) and grey (shower and dish water) holding tanks. These valves normally last a very long time, but eventually the rubber seals inside the valves wear out.
When this happens, you will get a small leak (or worse) that you notice whenever you go to empty the tanks. I first noticed that Sherman's might be leaking while we were on our way back from Florida. It was just a small leak, but I knew it wouldn't get better on it's own!
And of course it's not a nice job.
Today, Ruth and George (the maintenance manager here at the KOA) emptied out the holding tanks, and I bought all the necessary parts we might need to do the job. When I got home, it was up to me to take it all apart and do the repairs. It is possible to only change the rubber seals, but while you have it apart, it's wise to change the valve at the same time.
You can order them here...

One of the things you have to do is spray lots of silicon lubricant on the new rubber seals and the blade itself.
New valves work very smoothly!
The finished job!
