Help winterizing with air

[robert g]

I hooked the air to the water inlet city water inlet and could get no air to pass the valve my Roadtrek has 2 tanks one inside to use in winter with the other one bypassed. From what i understand the fill valve has a valve built in to release the water in the summer tank to drain. I can not get air past that valve there is another valve that is used to use city water and will also fill the tanks.I bypassed the water heater.I do not understand the function of the fill plug.I hope this helps thanks for all the comments i really appreciate them and any more is also appreciated
