I have a Weil Mclain Gold boiler that was installed in 1995. It recently developed a crack in the boiler block.
After talking to a couple of Gentlemen that have been in the HVAC biz for a combined 50+ years I learned that this is not an uncommon occurrence in WM's boilers from that time period. They attributed it to "faulty casting".
Can other HVAC professionals on this forum confirm this?
