sand filter problems

[stnygrm]

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

Hi Greg and welcome to the forum.
It is definitely possible for the pressure to climb fast when it's filtering a lot of stuff. Also depends on what kind of stuff. If it's larger particles then they will get trapped at the very top of the sand bed and raise the pressure pretty quick. When you backwash if you can look at the stream being dumped that will be a better indication of the amount of crud being collected than the sight glass.
