Thank you JohnT & ms. Actually, we think the culprit was the old hose that came with the pool (and the house in Feb). It had been tossed up under the deck..for how long we do not know. It did work for us for 3 or 4 times, but we bought a new one yesterday. The vacuuming went well. We appreciate your quick responses. This forum is so great.....all of you folks helping us newbies. Thank you. Joyce
