Shower drain leak

Hi. We have a 2017 Parkliner. We’re seeing a heavy leak under camper at shower drain connection only when pump is off. When shower drain pump is on there is no leak. Any thoughts or experience with same issue? Thanks.

Maybe the trap froze and cracked. Had one in our Casita that did that while we were winter traveling.
