Let me start by saying that I just bought a house and it came with an Above ground pool. I have never had to take care of one, but me being the person that I am, took it as a quest to turn it from green to clean. (The lady at the pool store knows me by name now.)
So, it came time to vacuum the pool. I primed the hose, placed the plate over the skimmer and turned the pump on. In normal operation, the pump strainer basket would be full of water at all times, but when I vacuumed, the level of water in the strainer lowered dramatically, and all you can see is a little bit of water trickling in from the inlet side. There is no return pressure at all on the return jet of the pool.
I know that you should not run the pump dry, so I immediately turned everything off.
I have a Hayward 1hp power flo matrix with 16" sand filter. I checked that there were no blockages, the hose is free of clogs, etc. The filter runs great in normal filter mode so no leaks in the plumbing.
I bought a new vacuum disk plate that has a larger diameter hole, thinking that this new pump was having trouble drawing all that water through the smaller disc hole. Still the same thing. I am thinking of buying the vacuum disk plate that has the 90 degree elbow so I don't have to feed the tube OVER the side of the pool wall to hook it up. Maybe it is having trouble drawing the water up and over the edge?
Help me out with this one please! Thanks!
