I recently encountered a scenario which I felt this group would enjoy
chewing on.
While draining an AF system to replace another leaking(@brass/steel
interface) no-torque head adapter, huge bursts of mist, aerosolized
glycerin mix, came out.
It seems that this company has an s.o.p. of pumping af into dead end
system(no purge) using a cheap pump which only permits about 50psi. They
then jack the system pressure above static with compressed nitrogen.
Has anybody ever seen this done before? Am I off base here or is this
possibly the missing link?
