Hi Soraya,

At the first sign the valve becomes sticky, we use vegetable oil to lube the
valve.

With the holding tank empty and the valve closed, remove the deck cap and
pour about a 100ml of vegetable oil into the tank. Let it sit for a little
while. Then, work the valve back and forth. This will last for a few months
before it needs to be done again.

(I am assuming the 54 has caps on the deck for pump-out like the 53)


With best regards,

Mark
