Dump Valves

[olson_phil]

I un-winterized my new (to me) Wanderlodge yesterday. When I went to
dump the holding tanks, the black water valve opened easily, but it
took me 20 minutes of yanking and kicking to get the grey valve open.

Once open I repeatedly opened and closed it about 10 times hoping to
loosen it up. About an hour later I tried to open it again and was
able to get it open, but it was still very stiff. Is there anything
that works to lubricate these valves? I don't want to have to
struggle
with these each time, but I also would prefer not to replace them.
