Specific: Water Leak 
Subject: T1/T2 Water Cooling Package Ball Valve Replacement 

5 and 3 Swagelok ball valves were replaced from the T1 and T2 cooling packages respectively.

These are compression fit valves, 1/2" or 3/4" size.

1 valve in T2 was replaced previously, bringing the total # of replaced valves in T2 to 4.

Remaining valves that need to be replaced:

  • T1:
    • 1x heat exchanger valve was not replaced because the heat exchanger line was not drained prior to the operation.
  • T2:
    • 2x valves for the heat exchanger line were not replaced because the heat exchanger line was not drained prior to the operation.
    • 1x M8 beam blocker cooling line was not replaced for the same reasion.

Remaining valves that may need to be replaced (verify after next leak check):

  • T1:
    • ~4 miscelaneous small valves (likely 3/8") were not replaced - want to check if they actually leak beforehand.
    • 2x panel mounted valves need to be inspected for leaks.
  • T2:
    • ~3 miscelaneous small valves (likely 3/8") were not replaced - want to check if they actually leak beforehand.
    • 3x panel mounted valves need to be inspected for leaks.
    • 1x valve from the resin flask outlet has threaded connections with plumbing tape - this valve may not be leaky.

Next week, will drain all water lines associated with the cooling package before replacing remaining valves - then perform leak check.

 Update: remaining valves replaced (see: https://elog.triumf.ca/TIS/RH-Meson+Hall/320)
