Subject: Yak-List: Old air system modification.
An aircraft I have an interest in appears to have the early version of the
air system. Notably, the pressure regulator valve, filter and NRV tree
is behind the rear seat.
Originally, I believe, there was an isolation valve immediately downstream
of the water drain on the engine side of the firewall. This is not there
now.
On the cockpit side of the firewall there is a line that runs from the start
valve to the EDP supply line that runs back to the tree. A NRV is
incorporated in this line.
Im thinking of removing this line.
Has anyone done this or is aware of any issues associated with its removal?

NRV = Check Valve ?
Well, yes and no! NRV means Check Valve, non-return. Not, for example
Check Valve, restricted flow, etc.
