In the "spare" hour I had this evening between getting home from work and going to the LR club meeting I pulled out the valve block, replaced the o-ring on the suspect NRV and the diaphragm.
Since it has been home, in the last 3.5 hours, only lost about 5psi and that could be due to self-levelling. Am pretty happy with that considering I just slapped the connectors back together, and drove off to the LRC ACT meeting with an EAS Buddy in the glove box... just in case

Can you explain what the diaphragm does. I will be taking out my valve block tomorrow for a re-check. I had a quick look at the diaphragm whilst I was doing the o rings. It looked perfect although there did seem to be a white powdery residue build up where it seats. I cleaned the residue before refitting. Did you use any of the o ring lube?

Hi Wayne
Here's how I understand the diaphragm to work... some smarter folk here please correct me if I get it wrong...
the diaphragm basically controls the air flow to ensure that all air passes through the dryer/filter. The solenoid that operates it is controlled by the compressor relay, not the driver block. When the solenoid is open, air flows in to pump up the reservoir and the springs. When the solenoid is closed, air flow out through the dryer before passing through the diaphragm and the exhaust silencer.
When I found air leaking through the silencer it may have been a combination of leaking NRV and/or diaphragm.
Cheers, Paul.
