I called Weil Mclain and they said warranty is 10 years only for parts,
labor is extra. So even if I was covered, I would still have to pay
someone to replace 1 section of boiler.
I am going to try the boiler liquid sealer and some kind of epoxy to
try and get me throught the heating season. Then I'll decide what to
do. This is a 360,000 BTU boiler for a 6 family Apt building, so it's
kind of hard to shut it down in the winter for repairs.
