We had something early last year, and probably Jon Cocca can help you better. Send him a message I cc’d him although he is on the list.
Our Oxygen leak was very small and was on solenoids 8 and 9.
Hope this helps somehow

I am slowly losing oxygen even in standby mode. I have replaced the regulator at the tank and leak-checked the whole line and the external and internal connections to the device regulator. Could there be a problem at the Costech oxygen regulator? Has anyone experienced this problem before?
