I just hooked up my sand filter pump tonight. I am a newbie, so I am not sure how it should be working. Everyone says they are so powerful, so I think something may be wrong. I don't feel much suction on the intake valve inside the pool. I also don't see water flowing in my filter basket. So I am wondering if I might have an air bubble in there like you talked about.
So should I have a lot of suction on the intake valve when I place my hand over it? And should I be seeing water flowing in the filter basket under the clear lid?
