Onboard plumbing sanitation and wastewater odor elimination on the 2023 Airstream Interstate 19 are managed by chlorine bleach solution ratios, gravity tank rinse ports, and specialized holding tank deodorizers.
How to Fix It:
-
Sanitize Freshwater Tank: Pour a diluted mixture of household bleach and fresh water into the tank, let it sit for several hours, and flush all lines thoroughly until chlorine smells disappear.
-
Deodorize Gray Tank: Add specialized RV holding tank treatment chemicals and fresh water down the galley and shower drains to break down grease and eliminate odors.
-
Flush System Completely: Run clean water through all faucets and drain both tanks entirely at an approved dump station to finish the sanitization cycle.
