Lippert 360 Siphon RV Holding Tank Roof Vent Cap | 389380, 389381

Stop the smell at the roof. The patented 360 Siphon can only pull air up, so in any wind — or none — it draws tank gases out the vent before they find the bathroom, and the fresh air it pulls through the tank speeds decomposition so you can skip the chemicals. No moving parts; 389381 adds a built-in bug screen.
