Helpful hints

Keep a small sealed container, with starter mulch and a ½ cup measurer in it, next to the toilet for convenience of adding mulch after each fecal use.

Hang a sign above the toilet, for the convenience of guests, that states ‘To “flush”: Add ½ cup starter mulch after each fecal use.’

For male urination, the gentlemen may either sit or stand close enough to the toilet so their knee applies a little pressure to the toilet seat and opens the compost cover

Troubleshooting

1. All vent pipe connections airtight?
   
2. Is the vent pipe inside the rubber connector on the back of the toilet?
3. Vent pipe ends at least 6” above anything within 10’ (see “Installation”)?
4. Vent pipe unobstructed?
   
5. Is the vent pipe insulated in all unconditional (i.e. attic) areas?
6. If there is a ventilation fan in the ceiling or wall of your bathroom, do not use it. The fan will draw air from the bathroom, causing a back draft through the toilet.
   
7. If there is a window in your bathroom and the air is drawn out through it, you should close the window.
   

If the odor is detected during periods when there is a breeze outside. Install an approved wind directional cap (part# wind) that is available from BioLet or your local authorized dealer.

Odors outside the structure
The presence of odors outside the structure is a positive indication that the vent pipe is in an area of air turbulence above the roof. The vent pipe must be raised to get the top above the air turbulence.

Excess moisture in the toilet
If you see excess moisture inside the toilet

1. Check that there is a good flow of liquid from the drain tube.

2. Ensure the mulch is not compacted and causing a “damming effect”, preventing the liquid from getting to the drain.

3. Ensure you are using the toilet within its limits of 3 people full time use (4 people with auxiliary fan) and 4 people part-time use (6 people with auxiliary fan).

Excess moisture in the composting bin
If you notice the material inside the composting bin is not loamy and appears to be holding excessive moisture:

• Are you mixing the material once a week?
• Ensure you are using approved starter mulch (see “adding starter mulch” in the “use and care” section above).
• Ensure you are adding a sufficient amount of starter mulch.
• Ensure there is sufficient ventilation from the toilet (see “Odors in the bathroom” above)
• Ensure you are using the toilet within its limits of 3 people full time use (4 people with auxiliary fan) and 4 people part-time use (6 people with auxiliary fan).
• If all else fails add 1 quart of coarse Perlite (available from most nurseries) to each gallon of starter mulch.
