auxilliary air compressor maintenance

[R J]

Hi John,

I could find only one drain line with a petcock on it.
It comes from the bottom of the air tank, which is
mounted above and between the 12 volt and 110 volt
compressors, and runs down and through the floor. It
won't pull out of the floor so I assume it drains
beneath the coach. I opened it, the 12 volt
compressor came on and I heard the sound of air
expelling from the tank. I looked beneath the coach
and I couldn't see any water spray or hear any air
noise. I left the valve petcock open for about a
minute and then closed it. The 12 volt compressor ran
for another few minutes and then shut down. Last nite
the 110 volt compressor came on and made that air
sputtering sound that compressors make over a hundred
times before 'closing', and then ran another minute or
so before shutting down. I must be missing something
here. Any ideas? Thanks.
