The seal was the problem--the old one just crumbled away when I took the pump apart. So now it's working, not leakng, but it's VERY loud..and since I had to run it overnite last night because I'm cleaning up the green that happened while I waited for warm weather to work on it, the longer it ran last night, the louder it got. So--am I correct in thinking my bearings are bad. And if so, What kind of time do I have before it quits?
