Sewer smell problem what to try next
We have a sewer smell when we leave the gray valve tank open. I have changed the air admittance valve in the bath room and made sure all p traps have water ( sink and shower) no smell in the kitchen....

Gray water tanks tend to be stinky if they are not cleaned well. I would add so,e bleach to the tank and fill it half full then drive over a curvy rough road. That should take care of the snell.
