We're trying to open our in laws pool. They usually have a pool company do it for them so they don't have much info for us. When we fired everything up it seemed to run pretty good. All of a sudden the DE filter started leaking from the bottom valve and now the pump won't prime. I'm attaching a couple of pics of the equipment. Nothing is marked so I'm not sure if the valves are open correctly or not.
Any suggestions to get the pump going?
