I opened my pool last weekend and ran into a problem yesterday. I had been vacuuming up the crud on the bottom of the pool and lost pressure. I have a Hayward DE filter and I cleaned the filter and tried starting again, still no pressure. The pump turns on and sucks out the water from the filter basket, but nothing comes in from the pool skimmer.
I put hose in the filter basket and the water ran back to the skimmer without backing-up, so I don't think the line between the skimmer and pump is clogged. I even replaced the gasket on the filter basket, but still no water flows from the pool into the filter basket. There are no leaks and I can't hear a "sucking" sound, so it doesn't appear to be a broken seal.
This is my second seasons with a pool, so I'm still relatively new at this. Any thoughts/suggestions before I call someone?
