water purge switch

[Hisham Amaral]

I am having a problem with the water purge air switch. I used the
system to purge the water last April on the way home to Michigan. I
started the coach last week and I am finding the air is coming from the
plumbing the system does not have any water at this time.
Does anyone have any suggest how to go about fixing this problem?
