Lube method for VERY stiff gate valves?
This past weekend was our first trip with the Outback and everything worked great, just as we anticipated after tested at the dealership and again at home. Well the one thing that I did not check prior to the initial trip was the operation of the dump valves. I have 2 T-handles inside the driver side cargo area, one each for black & grey tanks. The operation of the grey tank handle/cable is stiff, but workable and functional. The operation of the blank tank, on the other hand, is a true test of strength. I literally pulled with everything I had, leaning my weight in the opposite direction for leverage, to get the valve to open. Closing was equally tight, as was trying to reopen the valve during the flushing process I use.
I realize the ultimate solution is to open the underside and replace the valves. However, is there any possible trick to try before doing so that may help free up the valve?
In the meantime I dumped 3 containers of vegetable oil down the toilet to see if that may assist in conditioning the rubber seals/operation. I'm letting it sit overnight and will check this evening if there is any noticeable difference.
