P trap
Does anyone put a makeshift P trap in your sewer hose to prevent sewer smells from traveling back up into your tanks/rv?

There should be no reason to do such a thing.
Both valves should be closed unless you are dumping,hence no fumes to back up.
I leave the blank tank closed, grey tank open. Otherwise I'd have to dump far too many times with people taking showers, dishes etc. No need to take navy showers while hooked up!
