      Step-by-Step Instructions

      1. Remove the Old Toilet

      • Turn off your RV’s water supply.

      • Disconnect the water line. Cap it to avoid leaks.

      • Unbolt the toilet from the floor flange.

      • Lift it out and clear the area. Gloves recommended.

      2. Prep the Flange

      • Clean up the flange and surrounding floor.

      • Cap or cover the flange using the OGO™ Compost Toilet Flange Adapter.

      • Optional: Use PVC glue for extra odor seal.

      3. Install the OGO™ ORIGIN

      • Set the OGO™ in place over the capped flange.

      • Secure it using brackets or bolts as needed.

      • If using a Drain Kit, run the urine line to your gray tank or external container.

      4. Finish Up

      • Connect power to the 12V fan system.

      • Check venting. Make sure the vent hose is properly routed outside.

      • Double-check stability. Done.

      Common Questions (and Straight Answers)

      What Happens to My Black Tank?

      • It stays empty if you're only using the OGO™.

      • You can reroute the urine line into the black tank if you want.

      • Otherwise, just leave it alone — no harm done.

      • You can remove the black tank all together if desired.

      Do I Need to Rip Out Plumbing?

      • Nope.

      • Just cap the water line and adapt or seal the drain.

      • You can easily switch back to a flush toilet later if you want.

      Will It Smell?

      • No — if installed right.

      • The OGO™ separates liquids and solids and runs a constant low-power vent.

      • No sitting sewage = no nasty smells.

      How Do I Handle the Waste?

      • Liquids: Empty the container or drain it to the black tank.

      • Solids: After weeks of use, empty composted material into the trash.

      Pro Tips

      • Use good composting material like coco coir. Don’t skip it.

      • Keep the vent fan running. It’s low power but crucial.

      • Inspect fittings after rough drives. It’s rare, but worth checking.
