I have an 8 year old Jandy Stealth single speed pump. It gets used about 5 months of the year and is running about 8hrs a day. When the pool is shut down I rinse and dry it as best I can and store the pump in our basement. I'm wondering if it's worth while taking the pump apart and replace the o-rings and shaft seal as a preventative measure, or should I leave well enough alone and wait till I see signs of leaking in the future?
