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....

If a sewer burps your p traps may pass the pleasantly on into your rig even when they are full and working, most grey systems do not vent up the roof like the stick houses.....burp has to go somewhere....
