I am new to owning a pool and do not know what to expect. We set up our pool (Intex 12ftx30in Prism Frame) over the weekend and only ran the pump a few times and while we were not in it. Today when I went out to run the pump I felt the strainer grid and did NOT feel any suction. Is that normal? I know this is not a huge pump system and not very powerful but I did expect to feel some suction. Any ideas or knowledge shared would be greatly appreciated! Thank you!
