Late entry on yesterday's TCSX table water leak

Since it wasn't posted yesterday:

FRS Ticket 11569

[reply[−]Descriptionbetsy.weaver@LIGO.ORG 2018-10-01 15:30:08 CDT

This morning, TJ went to check the TCS chiller fill levels and discovered that the X one was showing nearly empty.  He filled it up, and went to inspect the table and lines.  Indeed, he found a 1 sec drip which had developed on one of the t-joints just inside the table enclosure where the lines enter the table and split into 2 directions. The leak caused a puddle on the table in the corner of the leak.  He and TVo cleaned up the leak.  We then added a trough to catch the water for now while we gear up for a fix tomorrow during the Tuesday Maint window.

We'll continue to monitor the trough fill level this afternoon.

We may need to turn the chiller off after commissioning completes tonight to avoid the case where the trough fills overnight.

The new fitting has been installed and the leak is tentatively fixed.  One of us will check on it near the end of the maintenance window to make sure there are still no drips.  We will also monitor the new fitting over the next couple days before declaring final victory, but so far we are leak-free.

With the new fitting in place, the leak seems to be fixed. We will monitor during today and the next few days to make sure before closing the FRS out.

I've attached some pictures of the table after I found the leak.

Jeff Bartlett is on the case this morning, hunting down the last remaining black plastic t-fitting which looks to be a replacement for what is currently leaking on the TCSX table.
