CompoCloset™ Maintenance Instructions

CompoCloset™ composting toilets provide sustainable and practical solutions to waste management, no matter where your adventures take you.

Like any other toilet, CompoCloset™ systems require regular maintenance to make sure they perform their best for years to come.

Adding Bulking Agent

In order to create a mixture that is ripe for composting, it is important to add a carbon-based bulking agent to the solids chamber. CompoCloset™ composting toilets perform best with a fine, moist bulking agent. While a variety of bulking agents can be used, the top recommendation is coco peat due to its fine texture and hydroscopic qualities.

Systems with an agitator—each time you start a fresh solids chamber, fill it with bulking agent until the top of the agitator legs are covered by about 20mm. Daily addition of bulking agent is not required.

Systems without an agitator—add a thin layer (about 1 scoop) of bulking agent after each solid deposit.

Mixing the compost (in systems with agitators)

Mix the bulking agent thoroughly with the waste to ensure even distribution. Manufacturer recommends mixing after every use, however users are free to find what works best for them. It's important to note that if you do number 2s, you must mix it in for best performance to blend the fresh with the old.

Spray Nature Flush Enzymes after use

Spray Nature Flush Enzymes (a universal cleaner and treater for compost) on the urinal and the chamber-screen after each use to ensure cleanliness and limit odours from excreta that may be left on these surfaces.

Regular Maintenance

Cleaning

Use a soft cloth or a paper towel to wipe off excess condensation, then spray the system with Nature Flush Enzymes and give it a wipe with the soft cloth/paper towel. Pay extra attention to the chamber-screen and the urinal—spray Nature Flush Enzymes on the these parts and rinse off with a bit of water, allowing it to run down the urine chute to prevent unpleasant smells.

Tip: For an extra deep clean, fill the liquids chamber with a white vinegar and water solution, then rinse.

Cleaning the solids chamber—cleaning the solids chamber is not required as a bit of compost in the chamber is beneficial in acting as a bio-active starter for your next compost batch. However, you may wish to clean this from time to time, in particular if you de-comission the unit (for disuse/storage)—spray Nature Flush Enzymes, scrub, and rinse.

Regular inspection

Inspect your CompoCloset™ composting toilet on a regular basis. Spotting issues early prevents them from developing into bigger problems. Take the time to carefully check every component of your system, including the solids chamber, liquids chamber, and ventilation system. During your inspection, lookout for signs of wear and tear, leaks, or any unusual odours. If you spot any issues, address them promptly to maintain the system's performance and prevent further complications.

Scheduled Servicing (Technical System Requirements)

Servicing the Carbon Filter (6–12 month)

Systems that rely on the carbon filter to remove composting odours require regular replacement of the carbon pellet inside the filter. This is a simple and inexpensive process, and should be done every 6–12 months.

Clean the Ventilation System (annually)

If your CompoCloset™ composting toilet is installed with an external ventilation system, ensure that it is functioning and that there are no blockages/obstructions that impede airflow. Clean your fan and remove any debris from the vent stack annually. If your fan is not working, replace it.
