Default Life of ch pumps?

pretended :
As a result of this thread
http://tinyurl.com/8um67 we eventually
replaced the pump with a Grundfos (and wired in a permanent live to
allow pump overrun) 25/55.

We bought it last spring and it was finally fitted around October.
Now, barely a year after being installed, it has failed. Grundfos give
18months warranty from date of manufacture and ours is now outside
that.

This doesnt seem a reasonable life for a pump to me - any advice?


Initial pump failed, or rather became noisy after six months. Second
one has run for 18 years in intermitant use 24/7/365.
