steam pipe banging

I inherited a situation where steam was brought to the third floor by a pipe connecting off the steam-feed to a second floor radiator.

When steam begins in the system, there is a period of loud banging in this pipe to the third floor.

The radiators are properly pitched for condensate to drain back in the one-pipe system. There is no such banging in other pipes, only in this pipe that was used to add a steam radiator to the third floor.

Any solutions? Is this a problem due to wrong size pipe-diameter to the third floor? How can problem be corrected? Thanks.

Either the pipe is of too small a diameter or there is a "horizontal" section of pipe run that has a dip that collects water (condensate).

In some cases setting the radiator up on small blocks corrects the slope of the pipe under the floor but this usually does not work when the pipe runs perpendicular to and through the joists.


The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.

You need some better venting for the third floor - I have gotten lots of great advice about my steam heat from
If I could only remember to THINK about what I was doing before I did it.
