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?

  • Empty boiler

    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
