In Reply to: Steam Radiators fill with water posted by Emery on September 27, 2004 at 14:22:35:
: Tested the heating system in my business this morning, and come to find out, the radiators all filled up with water when it was turned on. Still have hot water. Had pump in he cond. tank replaced last year.
First thing I'd check would be your radiator traps to be sure that they're not stuck shut. On a cold system they should all be open to allow most of any standing cond to drain out, this doesn't include F&T's, bucket, etc:, only the vent would be open.
Malfunctioning traps also effect the proper venting of the system.
Does the system hammer(bang) during startup?
And do the radiators heat up in a reasonable time?
