The shower sump used to discharge through a below the waterline seacock that also served as the intake to the old head. I had long since converted from the standard marine head to a Composting Toilet, which means I no longer required an underwater intake. This also means that I no longer required having this below the waterline through hull.
It is time to seal it up!
The seacock was always stuffed away inside this tine cabinet, which means that we couldn’t access it to seal it up. Now that the head is gutted, this is a wonderful opportunity to close up that through hull!
The sea cock was removed and the hole sealed on the inside with roving and cloth, just to keep the dust out while I grind the outside of the hull to make a proper plug.
