blocked water tank vent

[SLCohn]

The hose for the rear water tank vent will get water into it from the tank if too full. The vent line drops down as it passes thru the rear bulkhead before it is led up to the vent. Water gets caught in the low point of the hose and blocks the vent. No problem in the front as the line goes up with no down turns. Any suggestions on re routing the line? Steve Cohn, Elusive #060
