What Size is the Vent Hose for the OGO™ ORIGIN Compost Toilet

Everything you need to know about the included vent hose The OGO™ ORIGIN comes equipped with a flexible, reinforced vent hose that plays a crucial role in keeping your system odor-free and running efficiently.

What type of hose is included

The OGO™ ORIGIN includes a 3-foot steel wire-reinforced hose. This durable, clear-flex hose is built to maintain shape, resist kinking, and hold firm during installation or long-term use.


What size is the hose?

  • Outer Diameter (OD): 1.6825"

  • Hose End Inner Diameter (ID): 1.6"

  • Designed to fit perfectly over 1¼" PVC pipe

This allows you to integrate it into your vent path using standard fittings, making routing through walls or floors simple and secure.


What’s on the ends

The hose comes with two pre-mounted black hose ends—one on each side. These provide a snug, tool-free connection to both the OGO™ unit and your wall or floor fitting.


Can I extend the hose

Yes. While the 3-foot hose works for most installs, you can purchase a custom length vent hose. We offer by the foot.  Keep the run as short and straight as possible for optimal fan performance and odor control.


What if my install needs a different shape or routing

You can use PVC elbows, couplers, or flex adapters with the included hose. Just ensure:

  • A tight fit at the hose connection

  • A clean exit path for airflow outside your structure

  • The fan remains unobstructed and powered at all times


Final Tips

  • Always seal exterior vent exits to prevent moisture or insects from entering

  • Keep hose runs away from sharp bends or crushing points

  • If installing in a cold climate, insulate the vent path to reduce condensation buildup
