The tank will partly fill when heeling
In Response To: It will only flow out, to the extent that the bottom of the tank is below the waterline (maybe while heeling). ()
And then drain clean when level again. If I am over so far that the top of the tank is below the waterline and the thru-hull is open and the water flows back into the toilet the boat could sink. Not from siphoning but because the whole shitteree is below the waterline. Thank You SG, Brian, D'Arcy, Rich, Todd and Tom for taking the time to help me grapple with this shit before it gets out of control.

- Thin gravity holding tank question
- That tank will have a lot of pressure on it from the 40" of "head" pressure
- And you will have to pump up hill from the head to the top of the tank.
- You should pump up to a vacume breaker that is high anyway. You don't want to have the tank siphon back into the head.
- I checked with Raritan and they said I would pump up with no problem
- Not really...
- The sides of the tank have to thicker or reinforced more heavily to handle the deeper tank.
- It empties by opening the seacock and flowing into the sea

- I think he means that he won't pump the tank out, he'll just open a valve and it will drain into the 3 miles offshore...
- We have a gravity tank like you describe, butlarger
- What I suggest is...
