TJ reported this morning that he found glycol from the CS HEPI plumbing on the mechanical room mezzanine this morning. I went and looked, there is a large puddle where the the pump station manifolds are joined to the LVEA piping by some thick rubber hose clamped by pipe clamps. The supply line seems to have a very slow seep that has been dripping onto the mezzanine deck for an unknown period of time. Puddle is in the first image, the leaking connection is the lower yellow boot on the stainless pipe in the second image. I put down a bunch of pads to soak up the glycol and cinched down the hose clamp on the side of the boot that is leaking about 1/4 turn. I will come back and clean up more of the glycol and try to put some clean padding down to try to help with assessing how bad the leak is or if tightening the hose clamp fixes the leak. If this needs replaced it will be a huge mess and probably require shutting HEPI down for an extended time. If that is the case, we can probably lock all the HEPI's in the corner (like LLO does). I would prefer sealing the seep with epoxy if possible.
