If any valve was put to a pipe after the Exhaust outlet, check and ensure
that it is open.

noise shall be mitigated by breathing in slight air through the slow leak
valve.
Take off the slow leak valve if any trouble was predicted to breathe in
the air. That time the punch noise shall remain as it is.
