360 Siphon Vent Cap vs. Other Vent Caps

Dealing with a black water holding tank is something every RV enthusiast dreads, especially if the tank starts to affect the air quality of the RVs interior. Most vent caps cannot perform effectively with wind turbulence - the wind will be forced down into the tank, which will increase the air pressure in comparison to the air pressure in the RV. This drops the oxygen levels in the black water tank and pushes odors and gasses past toilet seals, causing them to seep into your RV living space.

The 360 Siphon will successfully and immediately eliminate these odors from your black water holding tank in any wind condition. When wind passes over the cap, it is designed to naturally create an upward vacuum in your vent pipe to exhaust any smells or gasses out of the holding tank to the outside of the RV. This drops the air pressure in your holding tank and prevents those smells from getting into the interior of your RV. By doing this, the 360 Siphon has created an oxygen-rich environment that helps further waste breakdown in the holding tank. Furthermore, the 360 Siphon provides you with a dependable, long-lasting solution, whereas perfumed chemicals can take up to 48 hours to kick in and merely mask the odors for a short period of time.

2 Installation Options

This maintenance-free vent cap is compatible with 1-1/4", 1-1/2", and 2" pipe stacks. If you have a 1-1/2" pipe stack, the included funnel is required for installation. If you have a 1-1/4" or 2" pipe stack, a PVC adapter sleeve (not included) may be required for installation. There are 2 options for installing this vent cap: modified and complete. Which option you go with depends on the current condition of your existing vent base and sealant.

If your existing base and sealant have been installed properly and are in good working condition, it is recommended to go with the modified installation. For the modified installation, you will first remove the lid of the existing vent cap. Then attach the funnel, if needed, to the 360 Siphon lid, and attach the 360 Siphon lid to the existing base with sealant (sold separately). You will also need to use the included collar to ensure a proper seal between the stack and base.

On the other hand, if your existing vent cap has UV damage or if it's not installed properly, it would be best to do a complete installation. To do that, you would remove the entire existing cap, including the base. Then you would install the new base with sealant and your existing hardware. Lastly, attach the funnel, if needed, to the lid, and attach the lid to the base with sealant. Please note that the collar is not needed for the complete installation.
