Not being very mechanical I was wondering if someone could explain what procedures will detect water in the systems, leaks in the systems, plugged pitot,... etc. Thanks fellow pilots for all the great discussions.

To check for leaks, connect panel end of tube to airspeed pitot and put tape over other end. Connect a syringe to static on airspeed and gently pull a vacuum until airspeed reads around 80 knots. It should stay that way for many minutes.

Applying pressurized air to plumbing that runs through the fuselage may cause some hidden connection to break apart. Always use a vacuum.
