Enclosed waste valve, drippage in compartment

Question

I have enclosed waste valves, and the hose connection fitting is inside the compartment too. And, like every RV I've owned, even with new valves, when I take the cap off the fitting, there is always at least a couple of ounces of brown water. It was bad enough messing with that on the RVs that had it out in the open. Now I find myself with that filth inside the compartment.

Am I the only one?

I probably should post a picture of the arrangement, to get suggestions on how to improve it. The easiest thing, which worked on my past RVs, would be to do put one of these on the fitting.

I'm not sure I have room for it, though.

I added a clear extender to mine so the cap would be attached outside of the compartment.  I did this to make it easier to hook up the hose, but it also solves the problem you're having.  I also hold the open end of the sewer hose under the cap to catch what ever dribbles out when taking the cap off.

If it is dribbling liquid you do NOT need a new do dad.

You need to replace the valve blade.
A very easy and inexpensive repair.
If the valve blade is not seated correctly in the closed position water will seep thru.

You might want to try cleaning it first:
With tanks EMPTY....open valve blade and take a brush and clean around the opening. Sometimes toilet paper will be stuck around there preventing the blade from closing correctly allowing seepage.

A correct/cleaned fitting valve blade does NOT leak. And IMHO just another positive reason to use RV chemicals in the tank to breakdown toilet paper so that doesn't happen. :W

Something caught up in the waste valve gasket?  Shouldn't be dripping.  That happens once in a while to me and I just replace the waste valve as it's not an expensive item.
