Some places require sewer hose supports so hose is NOT laying on ground.
Sewer hose support provides a graduated slope so stuff flows downhill
Course NOT all places/sites need or are set up where sewer hose support can be used.
I carry one and use when appropriate.
IF you really want to have a 'trap' in sewer hose....just spread sewer hose support and let section of hose drop down.
I don't cause a never leave dump valve open (Grey and definitely not Black).
Seen too many sewer flies inside CG sewer connection and don't want them setting up house in my holding tanks.
You do what he described and make a bend in between supports. Often, I find that over time one is created naturally for me... Many times, you can form a trap at the very end of the hose as the receptacle is usually high enough above the ground.
I create a trap as it costs me absolutely nothing and keeps the flies out of my grey tank which I always leave open.
