Don’t get your panties in a bunch we were networking. That’s what you do to better your knowledge by finding someone using technology you haven’t used yet. By the way I would be happy to take you out to dinner anytime you’re available.
Here’s one for the X-Files:
I got a call from an apartment complex of just over 200 units. The complaint was low hot water pressure in two of the five buildings. This complex was built in the early 80s and they used hard copper in the slab. The five buildings surrounded a courtyard and there was one circulated hot water line to feed the entire complex from Laars boilers which were located in one of the buildings.
This building was known for slab leaks from localized velocity erosion so I sent two guys out to look for a slab leak. After two days of looking for a problem my guys gave up and could not find the problem. The building owner owns a bunch of property and had been a good customer since the early 80s. There was no way I was going to call the owner and tell him my guys couldn’t fix the problem.
On the third day I went out with my guys to try and find the problem. I brought a bunch of unions and ball valves to isolate the buildings at each end thinking I would eliminate the buildings at the end and work backwards. The low pressure was working backwards from the boiler room and affected the last two buildings on the line.
Regardless of what I did I could not find the problem for the low pressure. Finally out of desperation I opened up the pipe at one end of the boiler room. I found the water was barely coming out of the 2 ½” line. I had already traced the lines in the boiler room so I had a pretty good idea of where the pipes ran. I took a 10’ length of 1” copper and shoved it inside the 2 ½” line. I found about 5’ in I ran into an obstruction.
After a bunch of work with the length of copper and my K-50 with a new cable I was able to clean the under slab pipe out. What I removed appeared to be glass which melted in the pipe. To this day I don’t know how the glass type materials got into the pipe.
The only thing I could figure was they had one of the boilers re-tubed by Laars. I’ve always wonder if Laars had some glass lining material in the tube they did not see and it got into the line when they re-tubed the boiler. The area with the obstruction was about 5’ from the boilers and seemed to be the only area which was obstructed.
Either way, the problem has not reoccurred and the in-house guys think we’re Heros. They had worked on it for weeks before they gave it to us and could not locate a problem.
