I am new here and really need some help. My pump intex 633t filter size B pumps 2500 gals. This just started a week ago and I am at a loss on what to do. If I put the filter in the pump it will not "suck" through the skimmer. However if I take the filter out it runs and skims perfectly with lots of suction. I have cleaned the hoses and tried everything. The filters are cleaned regularly and I even bought a new one. Please help!!!!!!
I have a Intex Ultra frame 12x24x52
