Someone here mentioned Company made water tables used air pressure to transfer the water from the tanks to the table. After viewing one water table and its fast water level adjustment, I presumed that is what it had. That zone member mentioned 2-3psi for this purpose.

I just completed a few glycol tanks for a customer, 9x12x72 in 12ga SS. In checking for leaks I kept it to 1psi as he claimed there would be no pressure on the tanks, BUT he said there would be no vent! I increased the pressure to 1.5psi just to examine the bulge on the 12" side. It was substantial and the load is of course 1500lb on the whole side at 1.5psi.

The tanks for my water table will be larger and not capable of handling anything near 2psi. Is the suggested pressure differential of 2-3psi wrong or should I be looking at using a small centrifugal pump to move the water? If it only has to raise it 1/2" to cover the sheet that's only 18 gal, a fairly short pump time between operations.

There is not enough room under the tipping table for round/tubular tanks.

Thanks for any suggestions,

Alan
