Water line blow out

I have for the last 18 months blown out water lines after each trip and to winterize the 179 but encountered a problem this time.  I applied ~ 35psi to the water lines through the city water plug and the system inside the trailer pressurized.  The water in the bathroom lines were blown out but when I turned on the kitchen lines there was no water being forced out of either the hot or cold water lines.  I'm not aware of any shut off valve to the kitchen lines and I've never had a problem in the past.  I did have pressure to the low water drain valves and as far as I can tell there are no leaks or loss of air pressure 

Originally posted by StephenH Check the faucet end filter to see if it is plugged. Do you get water from the outside shower? If not then the problem may lie between the pump and the kitchen area. If you do, then the problem is likely the faucet filter is plugged.

This is probably the most common problem reported with R-Pods.

At least it was something simple.
