After I backwash my Hayward sand pool filter (3 yrs old) it the pressure goes shooting up.? Tried backwashing it 4 times, twice with sanitizer, which is no easy trick cause I’m in the middle of the block and have to back wash into the street-so far no one has said anything. A lot of dirt is coming out. Should I just keep backwashing?
