[Drainage & Plumbing](https://learn.ogotoilet.com/03-mount-wire-vent?hsLang=en#drainage-plumbing) # Can I Vent My OGO™ ORIGIN to the Existing Black Tank Vent ## An advanced builder mod that can work—if airflow and moisture control are respected. We’ve seen some builders and vanlifers get creative with their installs and ask: **“Can I route my OGO™ ORIGIN’s vent hose into my RV’s existing black tank vent line?”** The short answer? **Yes—you can.** But this is an **advanced, optional modification** and must be done carefully to ensure proper function, safe airflow, and long-term moisture management. --- ### Why Some Builders Choose This Option Every OGO™ ORIGIN comes with a **3-foot vent hose** featuring a black rubber end that fits perfectly over **1-1/4" PVC pipe**. This makes it easy to connect directly to standard plumbing components. In some rigs, builders have chosen to **Tee into their existing black tank vent stack** instead of creating a separate exit for the OGO™ vent. This approach can: - Reduce the number of wall or roof penetrations - Route ventilation through an already elevated escape path - Consolidate airflow channels into a single external outlet But this method has tradeoffs—and **airflow and moisture control become even more critical**. --- ### Moisture + Airflow = Everything The OGO™ ORIGIN depends on a **continuous stream of airflow** to: - Dry out the compost medium - Prevent excessive humidity buildup - Ensure oxygen circulation for healthy aerobic composting - Eliminate odor before it ever becomes an issue That airflow comes from the **built-in, low-draw fan**, which pushes air through the vent hose and out of your system. Tapping into a shared vent stack can disrupt that airflow **if not planned properly**, and potentially allow **moisture or even odor to waft back into the system**. --- ### If You Choose to Do This, Here's How **This is a mod, not an official OGO™ install method.** But for those who understand the risks and plan their plumbing carefully, here's a general approach: 1. **Locate your black tank’s vent pipe**—usually a vertical PVC pipe running from the tank up to the roof. 2. **Install a PVC Tee** in that vertical run, ensuring you never connect directly to the tank or below the trap. 3. **Use PVC reducers/adapters** to transition down to 1-1/4" PVC for compatibility with your OGO™ vent hose. 4. **Ensure an upward path from the toilet to the vent**, so airflow continues outward and doesn’t stall. 5. **Flush and clean your black tank** thoroughly before install to reduce risk of backdraft odor. --- ### Pro Tips to Maintain Moisture Balance - **Never use this setup without an active fan.** The OGO™ fan must run 24/7 to maintain airflow direction and pressure. - **Consider a check valve or charcoal filter** in the vent path to prevent potential backflow. - **Monitor humidity in the solids bin**. If you're seeing condensation or a soggy compost medium, you may need more airflow or a separate vent run. --- ### Final Word Venting your OGO™ ORIGIN into your RV’s existing black tank vent is not standard—but it’s possible. Some advanced builders make it work successfully. The key is understanding that this is **not just a plumbing decision—it’s an airflow decision.** If airflow is compromised, **composting stops and moisture builds up.** But if airflow is well-managed, this method can be a clean and stealthy solution for certain builds. **Optional, advanced, and airflow-sensitive. Plan wisely. Build smart.** Need help reviewing your vent path or airflow setup? Our team’s ready to help you keep it clean and composting. - [01.
