comments: Continued investigation of TT gain / drains on rig floor. Found 6" drain line blocked and diverted through a 2" line to rig's drain system.
2" line too small to handle heavy rain, causing overflood in the diverter which again caused gain in TT.
Opened annular preventer and monitored well on TT.
Meanwhile: performed maintenance on Drawworks.
