I've been operating with the assumption that my plumbing setup is unique, and therefore my backwashing process is different than most. I want to run this by the experts to make sure.
My pool equipment is in my basement, below the level of the pool. When I move the valve to backwash, the flow to waste through the 2" drain hose is strong without the pump. I've only turned the pump on once during a backwash, and it increased the flow so much that the waste hose "levitated" and shot out of the floor drain. Since then, I've let gravity do the work during backwash and rinses.
Not having a basis of comparison of how much flow to expect, I'm not sure if my 2.5 - 3 minute, gravity-driven backwash cycle through a 2" hose is appropriate.
I'm wondering if I should secure the waste hose and run the pump, or extend the cycle time and continue to use gravity.
