Still would need more details but, I would turn on water pump if it doesn’t leak down or cycle you know it’s not the fresh water side. Did it rain? Shower drain? Have you used toilet or shower? Need more investigation, could be a multitude of things. Only happen when you ran rear AC? Determine what you did last or what changed recently and go from there. That’s my .02
