Rinse your sewer hoses when leaving full hookup site?

My water hose has a Y connector at the hookup end. I carry a roll up Pocket Hose. I use the pocket hose to flush the stinky slinky as a I disconnect from the coach valve.

Comes in hand for washing off the front of my coach also. I never use my white fresh water supply hose for anything but fresh water.

Of course this after a black tank followed by a grey tank dump.

Hope that helps
