I just purchased the Krystal Clear Sand Filter Pump Model SF70110 for my 18x48 ultra frame intex pool. I also bought a new vacuum head but I'm having a problem with the debris getting clogged in the intake connector of the pool. Their is no way of taking the strainer off. I had to use an adapter that screw on the strainer in order to use the hose. I vacuum the pool and when I take the connector and hose off all the debris goes back into the pool. Very frustrating. Anyone have any advice on what I could do to prevent this?
