Two things odd started last night when running my pool filter.

1st) when I turned on the filter I noticed water was not pulling thru the motor after I cleaned the filter. I filled with water and it started to pull but at 50% of what it usually does.

2nd) the pressure on my sand filter is very low. can these be related. My pressure is usally at 30 now is around 5.

any advice would be great. I have an in gound pool.

thanks!
