We just bought a new (to me) boat
and will be replacing the waste system (tank, y-valves, macerator etc) with a composting toilet. In order to remove everything, I have to shut off the discharge seacock. However, when I go to turn the handle it comes in contact with it's self and I can't close it. (see pic attached)
I think I could remove the pin and turn in the other direction to close it off, but access is a little difficult. I might be able to rotate it if I removed the hose, but then I will sink the boat! I can't understand how the PO could install a seacock in such a way it couldn't be closed.
Is it possible that although the handle is vertical, the seacock is already closed? But then how did the PO open it. Am I missing something? As an additional clue, I tried running the macerator today and it just spun and came to a halt, leading me to think that the seacock is closed and the macerator can't pump
out. But the handle is vertical?!
Part B to the question: Assuming I actually close the seacock, I'd block off the pipe as a secondary precaution until I can haul out
and physically remove the through hull
and glass over the hole. What would you recommend I use to terminate the 1.5" hose ?
P.S.: It is entirely possible the PO had no idea what he was doing. The air vent for the waste tank goes so low into the boat
that it entirely fills with waste water
before going above the waterline. The whole system is quite recent.
