Compressor Pump Down

Same way I do it Taz. The remaining gas will be indeed very small, just the portion above the piston and the very small volume in the discharge valve.
This is something you don't find in schoolbooks but only can learn in practice, which you have.

Thankyou Peter.

Iv'e been at it for 28 years now.
I'm still learning.
I was taught by some good engineers and was taught to leave the system running if possible no mater what the fault.
