My Storm 28MS has the standard push pull valve to empty the waste in the tank. At times it is difficult to pull and push that handle on the valve. Anyway to lubricate that valve? I saw a video once that said I could drill a small hole above the opening and attach a flat pan head screw in order to spray the inside of the valve with WD-40 or some other lubricant then attach the screw back. Another article said to pour some liquid in the kitchen sink. Of course both of these ideas are done after the tank has been drained. any suggestions?

Search this Forum for `Black Tank Valves' and read the suggestions. Depending on how old is the rig you might want to consider replacing the valve with Valterra. If the handle does not have a name on it it is probably a Bristol.

Some of the waste tank deodorizer products say they lubricate the valves. I don’t know how effective they are. I have had relatively good success in just lubricanting the metal shafts with either a spray silicone lube or a grease. WD40 is a good cleaner but not a lube. There really isn’t much you can do when the valve is in the closed position.

Well, don't waste your money on the stuff you pour down your toilet and it's suppose to lube the slide valve. I think that was the biggest waste of money I ever spent on any of my campers. I tried two bottles, and it never made any difference. So, in my opinion, that is just a bunch of snake oil, a way to get you to separate with your money. Shoot! It didn't even work on the slade valve in my toilet bowl. That dang thing still stuck. Here's what you are talking about from Trailer Life Magazine, 10 minute tech: I've never done this because my slides are all enclosed. I've have to cut the colorplast to access them. Sounds logical though, like it might work.Click here.

Thetford Drain Valve Lubricant made my next to impossible to move black water valve move easily. :B

Just thinking out loud here; I wonder if using some very fine steel wool on the shaft just to clean it up and then applying a little paraffin wax or plumbers grease would smooth one out.

I have used the method in the Clicky for many years and I am here to tell you this really works!

I did this exact thing over the weekend with great results. I can slide both valves easily after about 10 minutes.

Back in the good old days a Zerk fitting was installed and grease was added every now and then. I been doing it for 20 years and never had a stuck valve. Only takes a bit of time and $.

I installed self tapping grease fitting to the top of the black and grey valve years ago, what I found the grey valve never gets had to pull it is always the black valve. I usually pump grease into the fitting every other year or so and it lubes the seals and makes it easier to pull.

A tech did this for me on one of my valves and it made a world of difference.

Bingo! I use laundry soap in the black tank. Keeps every thing slippery.

I installed grease zerks in my drain valves, when I purchased my Bounder 15 years ago. No sticking. Before you suggest grease deteriorates the rubber seals, the seals are NOT rubber.
