Interesting. I had entered the less than symbol and everything after it was not posted.
What I had posted was:
33 feet of water = 14.5 psi three feet of water is less than 1.5 psi.
The actual pressure exerted at the bottom of a tank three feet high basically containing water is 144 times 1.5 or 216 pounds per square foot.

- 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

- 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
- And you will have to pump up hill from the head to the top of the tank.
- 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...
- That tank will have a lot of pressure on it from the 40" of "head" pressure
