Re: HELP i'm in a complete mess and don't know which way to
Do you have a valve in your suction line between the skimmer and pump? If so, close it, open your skimmer basket to let the water out and then take the hose off the pump outlet ( the clear hose on the right ( I guess you need a valve in the return line or you can move the multivalve to isolate the pool or you can hold the hose end above the level the pool waterline) .
This way you can see inside of the pump outlet and into the impeller. Un plug and then see if you can get the impeller to move. Use a pencil or something to make it move. If it moves with some (not great) resistance, you know the impeller should be free but if there were a rock or something else, ift may only lock the impeller with the motor spins it fast enough.
I kust read you latest message... yes, it will drain the pool. Do you plug your vacuum hose into the bottom of the skimmer?
