not sure of the size of the filter, it took 2 bags of sand,
it says splash pac 160 for the model number.
the pump is a hayward power flo xl.
it seems to be getting better as it has been 2 hours since the last backwash and i am
still at 10 psi.
is it possible that the water was so dirty that it was clogging the sand?
thanks and let me know,
greg
