I just bought a home that was built in 1996. I do not know much about how the skimmer works other than it is suppose to have suction. Mine does not. There are 2 capped pipes inside the skimmer hole. The filter works fine but there are 6 jets and the one next to the skimmer and the one across from the skimmer do not work. the others work great. Any information on what I need to do would be great.
