I'll let other chime in about leaks and noise coming from a failing pump. What concerns me more is the silent killer, the plastic impellers that can break off and clog the system creating hot spots and cracked heads. I have a 14 year old pump with 25,000 miles on it. The preventative maintenance side says to change it now or risk disaster. I am leaning towards doing it sooner than later.
