The holdingtank has been made after my drawings. Inlet pipe (to right) is running up inside the tank close to top of tank and will be connected with hose from the toilet. The outlet pipe (to left) will be connected to a 5/4" ball valve and out to sea. So - when i harbour, the ball valve is closed, and when you are at sea (more than 2 nautical miles away from shore), you open the ball valve and empty the tank.
Thats how my system shall works.
There will be a shelf on top of holdingtank, and the fridge will be in front. |
