Air Pressure Leak

Recommended Posts

I just started working on a new to me 98 Discovery.  Air would leak down in less than an hour.  I was airing the system up with my shop compressor and when I disconnected the airline  air came out.  The check valve at the drier was stuck open. I replaced it then the purge valve in the dryer had a small leak.  The air in the tanks leaked back to the drier so I changed the valves at each tank. Now it holds pressure.

Wonder if the dryer was WAY past due for servicing.  Maybe water or worse filter media got in the system-- can certainly contaminate the check valves.

Look forward to hearing what you find in the wet tank drain.

Good luck with it.
