Air bags deflate over night

[Thor 37GT]

Overnight my air bags would deflate so this is what I did.
Problem:
First I found the air was leaking out of my purge valve on the air dryer.
The purge valve was leaking and purging every 3 to 5 min.
Fix:
Installed new purge valve kit. $50.00 ebay
Problem:
Purge valve no longer leaking but still purging every 10 min.
Called Wabco and talked to Kyle
Fix:
Kyle said to change the governor after doing a test. Test was inconclusive.
governor $25.00 ebay
Problem:
Purge valve not purging but rear air bags release all air in 24 hr. period.
I could put my ear up to the air dryer and hear air leaking inside the air dryer. Talk with kyle and he said the check valve was not working to replace the air dryer
Fix:
Replaced air dryer ss1200 wabco. $100.00 ebay

Everything is working
Pic with bubble is the purge valve on the bottom of the air dryer
pic with black filter is the air dryer
pic with the air chuck is the governor
governor location is to the left of the air dryer behind the fuel filters

$100 for the whole air dryer? Dang... The rebuild kit for mine was $95. Did that include both filters?

I had a problem with my purge going off every 10 sec or so and it was the Governor. Air compressor was running all the time. Luckily I didn't burn it up.

Mine only has one filter

Mine has a coalescent filter that goes into the bottom before you put the Desiccant filter on the top.

How long are air bags supposed to stay infated? Don't they all deflate over a period of time if you don't purge them?

I talked with spartan and they said it will very 3 to 4 days. Mine will last about 36 hrs. They said that is still ok.

Never checked mine.... believe I will do that!

My fronts were leaking down overnight and I replaced the check valve on top of the tanks that is before it splits to the 2 bags. It seemed to stay up several days to almost a week, but that was short lived. Now after about 3 or 4 days they seem to just go from air up to all the way down. The back bags seem to stay up for a long time. I'm in the process of replacing the front airbags and ball joints, so I will check for leaks again when done.

I've had mine leak down overnight, and then times where a week later there still aired up.
