ANY AAV WILL WORK IN AN RV
The myth:”An air entree valve is just a one-way vent. Any AAV from the ironware store will work in my RV.”

AAVS ELIMINATE THE NEED FOR A ROOF VENT
The myth:”Install an AAV and you can ditch the roof vent entirely. One valve solves all your discharge needs.”

AAVS NEVER NEED MAINTENANCE
The myth:”Once installed, an AAV lasts forever and a day. No cleaning, no checks, no worries.”
Why it s wrong: AAVs take in dust, lubricating oil, and dust. Over time, this gunk clogs the valve or prevents the seal from closing. RV motion can also loosen the bound, causing the valve to sting open. A stuck-open AAV lets cloaca gases into your RV. A perplexed-closed one creates vacuum-clean locks, deceleration drains. Many RVers don t see their AAV is failing until they smell up icky eggs or hear gurgling pipes.
The truth: Inspect your AAV every 6 months. Remove it and rinse the valve with warm water. Check the seal for cracks or buildup.
