Steam Hammering after re-work
I have lived in houses with steam heat for many years. I understand the principles but have not had time to fine tune my system. The question I have relates to the WORST steam hammering I have ever heard. This summer we finished our 1930's era basement. We hired a large, well known local mechanical contractor to do the steam pipe work. I have three concerns, which I spoke to the tech about before the install;
-Originally there was a steam line around the perimeter of the basement wall on the front and right sides of the house. It was about 8" below the floor joists and 18" from the wall. We made a bulkhead around the front portion of line and rerouted the right side portion to run flush to the wall behind a 2"x4" stud false wall. The line also had to be routed DOWN to clear a window it previously ran in front of. So the line now has a 90 L toward the ground at the wall and a 90 L towards the rear. It then T-s to a vertical line to a 2nd floor radiator. This vertical line also continues to and under the basement floor back to the boiler.
-Originally where the perimeter line connected to the vertical line that runs to the 2nd floor radiator there was an air valve. When the lines were reconfigured they did not install a new air valve.
-Insulation was not installed on the new lines (one of which is now flush with the basement exterior wall) when they were installed.
I questioned the tech about each concern (change in pitch of steam line, elimination of air valve and insulation) before the install and was assured that there would be no problems.
Was this job done correctly? If so, why else would I have this hammering that I never had before?
If the work was not done correctly and warranty repairs are required, should I expect the mechanical contractor to cover the expenses of removing and replacing the new studs, drywall, paint, etc? I would want to use the carpenter who finished the basement.
Please let me know if you have questions that I can answer in order to help.
Thanks in advance.
