Hello, I'm a complete newbie. This is my first pool and the first time turning my pump on and I think something is wrong. I have a 27ft round above ground pool with a Hi-Flo pump and a Clear Water II cartridge filter. Everything sounds normal but I'm not getting a pressure reading on the gauge at all. There is a slight water movement at the return so I know it's at least moving some water. I think the basket is supposed to be full of water but it looks like about half full, kind of hard to see. I attempted to take the cover off with the pump on and water shot out. I managed to get the lid back on and when I did the pump sounded different and I noticed the pressure gauge jumped to about 3psi or so for a second and then dropped back down to zero.
Any help would be greatly appreciated.
