Cast Iron boiler leaking again after repairs
have a 15 section HB Smith cast iron hot water boiler (12 yrs old) that began leaking in the mid area (on both sides) last yr. it was repaired by replacing some gaskets (no sign of a crack)
and now its leaking again (a slow leak)
started chemical treatment after the repair (not chemically treated since installation, and lots of new water has found its way into system when system pipe repairs done)
does water temp effect rate of leak (ie. keeping boiler hotter vs less hot)
and now the question is what to do?
