i decided to test the operation of our optional seawater flush on the forward head. I’ve never used it before and In the absence of any instructions in the user manuals, I opened the seawater valve and tried to flush. There is no seawater being pulled through at all.
Can anyone advise if there is an additional step I need to do to make the seawater flush work.
I know it worked when we bought the boat because it was checked off by Olivier on survey, so I’m sure I must be missing something.
