80 year old Manhattan apartment building (18 stories, 175 units) has a chronic problem with the steam pipes banging in the winter.
Management has hired more than one ‘expert’ over the years to troubleshoot the problem with disappointing results.
After about 2 or 3 weeks into the cold season the pipes start to bag when the heat comes up. It gets progressively worse all winter and at times you can actually hear water rushing through the steam pipes just before they get hot. The staff have made numerous modifications to the radiator pipes, paying close attention to such things as the aspect of the return lines, but it seems to help very little.
Q: If I could convince management to take another go and fixing this, what discipline and approach would have the highest likelihood of success? Simply put; who do we hire and how do we insure we’ve got the right person?
