Why would you need to lift in different stages? If you take the top 3 feet out of the pipe, the water pressure will push three more feet into the pipe.
Am I missing something here?
- lazide 3y agoThe membranes require hundreds of feet of head worth of pressure, not 3 ft. The pressure at the membrane will only ever be the difference. It has nothing to do with the depth the membrane is actually under the water.
- jethro_tell 3y agoThat makes sense, but then, why put it on a pipe at all?
- lazide 3y agoNear as I can tell, it offers no actual advantage to do so, and creates several serious disadvantages.
