and get a heating pro in there....any pro for now. It sounds like you could have a blocked pigtail or non-working pressuretrol - THIS IS VERY DANGEROUS! THat's more than 15 pounds of steam exiting that valve. Keep family and pets out of basement until it is corrected. Mad Dog

    Steam system one pipe

    The main relief on the furance keeps lifting filling the basement with steam. The raditor vents all seem to be working reliving the pressure/steam This has never happen before Boiler is probably 40 years old Its a one pipe steam system I have replaced 4 of the 8 vents on the raditors
