[labnetwork] MAU Steam Coil

[Brian K. Olmsted]

We've had to back-flush several of ours because of poor water quality
causing blockage issues, but never had to do repairs because of leaks.
However, we do have a periodic leak in a steam coil for our main AHU.
Facilities management staff repair it by soldering or torch brazing to
repair the leak.

Thanks,

Brian
