The pump that the well driller installed after drilling the well deeper is labeled 3/4 - 5 (written on the pressure tank). The pump is at 390 feet and the static water is about 110 feet down. After researching media types I see back wash rates in the range of 8 or more GPM. I am now getting nervous that this pump will not be able to backwash most media I would use in the tank.
The filter tanks seems to be 10 inches, so that makes the area about 0.79 sq ft, so I think I get 6.4 GMP for backwash best case, right?
