I have just opened our pool this year. The fittings to our pump are glued PVC not screwed and seem to have 2 small leaks. So I am assume that's why I am not getting the suction I normally get. My pump motor seems to run fine and water is flowing through just not the way it usually does. The skimmer baskets are all fine but the water isn't pulling very well. Because the fittings were glued we would have to cut them to replace them. Is there something else we can try first to seal them?
