My pool handle is sticking when I try to back wash or reposition to the original flow. The bearing washer/gasket just below the handle has been cracked for some time now, which may be the cause of it sticking. Do you have any suggestions for what I should try before breaking down and hiring someone? I am somewhat handy with a little guidance or suggestion. The pool is about nine years old, and I have never replaced any parts on it, so it is about time that some of them are wearing out.
