Pump on Jabsco toilet occasionally gets stiff. I then take out the six screws on top of the plunger assembly, wipe the cylinder wall and rim of plunger gasket with a lubricant. I’ve tried various readily on hand lubricants (olive oil, etc) and this is good for a few days and gets stiff again.
What lubricant do you think might be impervious to the corrosive effects of piss water?
