Just a quick question about Sea Cocks on a jabsco sea toilet.
I know how to work the flush & refill and I know that the sea cocks should be closed when the boat is left (on a pontoon mooring). But in the user manual there are warnings about closing the sea cocks when not in use.
Now does this mean that they should only be opened when someone needs to use the lav? (Cue. crawling on hands and knees and lifting 2 locker hatches OR can I open them before a trip and then close them before leaving the boat at the end of the day.
To avoid questions, the toilet was professionally installed at the time of build (Hardy Marine) the previous owner had never used it and simply did not have a clue about this question... there's quite a lot else he didn't know.. but that's another story!
