What makes you think it is on its way out?
What kind of underground piping do you have, exactly - and how old is it?

Curious on this. I have a Taco 007 on my primary loop that has basically run continuously for the last 9 years. I unplug the boiler in the summer but this pump stays running.
What is the hr life of one of these?
Being that this pump is installed outside it would be a pain to change in the middle of a cold spell.

Symptoms are usually noise for a failed bearing. The other failure is a stuck impeller caused by crappy fluid conditions.
Normal use should be 15-20 years under best operating conditions.
Excessive stop and starts shorten the life of any motor.
Centrifugal pumps do like to have some positive pressure on the suction side, maybe 4 psi at 180 temperatures. Outdoor open systems do not always assure that and pumps fail prematurely on those systems. Always have a spare and valves on both sides for quick, easy replacement.
