Can you drain an inground pool with the pools back wash?

Let me say first backwashing is a process for simply ridding the filter of dirt, once you backwash the pressure and cleanness of the filter will begin to collect and store more dirt from the pool, Look at the gauge at the filter remember the pressure or write it down as the pressure goes up the flow of water going back to the pool will go down to the point that very little water will go back into the pool. When the pressure is low the water flow from the filter will be high meaning that the filter is not clogged or dirty.
