Leaking radiators (through ceiling)


One of my third floor radiators leaks through the floor and through the ceiling below if I turn the thermostat over 68 F. The pressure on the boiler is 2psi and there is no water in the sight glass. Any suggestions?

    Check your LWCO for function, as it should not allow the boiler to fire without water in it.

    Your pressuretrol may have failed due to a plugged pigtail, and allowed the resulting over pressure to push water out of the boiler into the mains.

    Some service by a steam professional (not a plummmmmer) is required!--NBC
