Altitude valves for an underground tank

Altitude valves for an underground tank

Altitude valves for an underground tank

(OP)
All,

Hi, I was looking into using an altitude valves for a buried "underground tank". how will this valve sense the high water level in the tank if it will be positioned above the high water level.

Would a simple solution of lowering the altitude valve to below the high water level solve this ? this off course will increase the altitude valve chamber cost as it now deeper than before.

thanks all.

RE: Altitude valves for an underground tank

You could do that if you want to construct a valve pit. The valve pit would need to be large enough for a man to access and perform maintenance on the valve. Maybe you already have this. I suspect the pit would cost substantiually more than the valve.  

Or you could mount the altitude valve above ground level, and put a dip tube to the bottom of the tank, with the valve's sensing line attached to it.  Tee a bubbler into the sensing line, and the pressure that will be required to force bubbles out of the tube will be the altitude of liquid above the end of the tube.

Use a pilot operated altitude valve.
