What You Will Need

Before we start, gather the following tools and materials:

  • Drain Away Kit
  • A piece of hose to plumb away the urine
  • Cuddy composting toilet
  • Drill with a hole saw for your hose
  • Pilot drill
  • 3.5-millimeter drill bit
  • Phillips screwdriver

Inside the Drain Away Kit

The Drain Away Kit includes:

  • A bracket to mount the kit
  • The urine drain, which snaps into the bracket
  • A 5/8 hose fitting (standard in North America)
  • Small screws and bolts
  • A Jubilee clip to secure the hose

Step 1: Secure Your Cuddy Composting Toilet

First, you need to secure your Cuddy composting toilet in place. This step is crucial because you don’t want to remove the hose and open it up frequently. Use four screws to secure the Cuddy to the floor through the islets provided.

Step 2: Prepare the Inside of the Cuddy

Remove the solids bin, fan, and urine bottle from inside the Cuddy for convenience. This will give you more space to work.

Step 3: Position the Drain

Inside the Cuddy, you'll see where the carbon filter, solids bin, and urine bottle usually go. Keep the handle in place as it should not interfere with the drain. Line up the drain so that it is centrally located and does not interfere with the seat. There are two holes at the front and two at the back for mounting the bracket.

Step 4: Assemble the Drain

Snap the top part of the drain into the bracket. This may require some force. Then, attach the top ring to ensure everything is clear before the final installation. Make sure the front edge of the bracket is flush with the front of the seat.

Step 5: Mark and Drill Holes

Mark the holes for the screws. Drill two shallow pilot holes to help get the screws started. The screws are stainless steel and can be a bit tricky to handle. If possible, have someone help you with this step.

Step 6: Secure the Bracket

Align the screws to go into the vertical section of the plastic. Be careful not to drill too deep. Secure the screws into the holes to keep the bracket in place. Ensure the bracket does not move as you assemble the rest of the drain.

Step 7: Drill Holes for the Bracket

Use a 3.5-millimeter drill bit to drill two holes through the bracket. Use the bracket as a guide to ensure accuracy. Insert the nuts on the bottle side to secure it.

Step 8: Install the Valve

Reinsert the valve into the drain. Apply a bead of silicone around the inside to help seal it and hold it in place. The drain can be directed left or right of the central agitator shaft. Snap on the valve to finalize the connection.

Step 9: Drill the Base Hole

Drill a hole in the base of your Cuddy composting toilet to route the hose. Ensure your drill is set to rotate in the correct direction.

Step 10: Attach the Hose

Slide the hose over the adapter and secure it with the Jubilee clip. Tighten the clip to ensure a snug fit. Route the hose to your desired drainage location.

Final Checks

Once everything is in place, check all connections to ensure they are secure. Test the system by running water through the drain to confirm there are no leaks.

By following these steps, you can efficiently install your urine Drain Away Kit, making your composting toilet setup more convenient and sanitary. Enjoy your hassle-free composting experience with Cuddy!
