im new to this but we bought a used 21ft round pool got it all set up realized that the pump was bad so we bought a new one 1hp same as the one before it. we set everything up how it should be turn it on and for the first 5 mins its fine it runs quietly and everything seems right then all of a sudden you hear the pressure build up and the water coming out of the return starts moving so fast it makes the solar cover push to the other side or when my kids were inside the pool it was making all there toys float to the other side and stay there. we bought a pressure gauge for it and its not working so i know we have to replace that in the morning and the pump is off now. but i wanted to ask on here what would cause that kind of pressure build up i dont believe there are any clogs or anything everything was taken apart and put back together twice. the floaty thing in the skimmer doesn't really float it just gets stuck down and if i lift it up its like a toilet flushing if i hold it up after 5 mins or so bubbles start coming out of the return... sorry im such a newb
