I also had a small leak when using the flush. It was hard tightening the hose on the connector, it would drip into the compartment and eventually onto the ground in front of the streetside front wheel. Made up a 2' section of hose, double washered the end, tightened well and left it connected. Now just attach it to the outlet valve or city water and flush away.

So when is this..."old enough to know better" supposed to kick in?
