Two things come to mind, !st Check the roof vent for blockage. I have ran a garden hose to flush out a vent line plugged with leaves etc. had no vent cap. 2nd there should be a room vent or vacuum break under the sink coming off the drain. This could be stuck open allowing fumes to enter the space. How old is this unit? Could it be coming from fresh water tank? You can sanitize the tank and lines with 1 cup bleach to your freshwater tank fill the tank the rest of the way with water. Turn faucets on one at a time until you smell the bleach. Let stand at LEAST 4 hours then drain. Fill the fresh water tank again with fresh water. Run each faucet until you no longer smell the bleach in each one. You are now sanitized. You should probably put the water heater in by-pass mode when you sanitize the system unless that tank is full of crud as well. Hope this helps!
