i have a pool, round 18'x52", on level ground w/ a sloped hill behind it about a5 ft away. my idea is to use the bottom drain hole on the pool to move water into a 50 gallon sealed barrel filled w/filtration foam, (to be located below the level of the pool on the slope) and to move water from the 50 gal. barrel back up to the top back into the pool. how do i figure the drop to give enough pressure to bring the water back to the pool ? please help....Pat
hi....Gravity fed water pressure varies depending on several factors. The location of the water tank, the size of the pipe, devices installed on the water line, and the path of the pipeline all determine water pressure. The key is to choose the variable to adjust that costs the least to manipulate.
