I cannot find the correct pump tune up kit for this pump. It was leaking when I turned it on for the season. It is for an above ground pool and I keep in indoors all winter. Wondering if just a new O ring will do the trick or if I might need to try to take the impeller off. I'm not very handy, but I try to be. I love your videos on how to do things, but when I try I'm not always successful.
