[Korean plumber] You're going to get claustrophobia! Replace the valve where only the arm moves!

Hello?
Plumber's facility Vlog channel 'Sulbu Log'.
I have to go into the pit room and work
It's such a small space
I almost had claustrophobia.
Still, I installed the 25A valve well and came out.
Please watch until the end^^
