Or house was built in 1927. It is an old victorian. In the winter of 1999-2000 we sustained a crack in our boiler (used for steam and hot water). A local plumber came, sealed it and suggested we look into a new furnace. We got the new furnace (runs good) but, since this incident, one of the radiators is blowing out a lot of steam every time the "heat" comes on. It also blows out very hot water. The bleeder looks like it is cracked, can that be replaced? Should it be blowing out any water at all? I asked the plumber he told us to raise one side - done - didn't work. Help!
