How we repair your Composting Toilet
A composting toilet separates or collects human waste in a chamber where it breaks down with airflow and bulking material, with no sewer connection. A composting toilet usually involves a motor or ram, switches and safety interlocks, and seals, or a passive system of baffles and drains. A technician checks power and switches, clears jams or buildup, and inspects seals and connections for leaks.

Most composting toilet repairs fall roughly between $100 and $350, depending on the part and labor involved. That is a national ballpark estimate; you get an exact quote after diagnosis and before any work starts.
Can you repair my composting toilet the same day?
Often, yes. Call (844) 442-1999 early in the day and we will try to schedule a same-day visit. Same-day service depends on technician availability and whether the part is in stock.

Yes. Completed repairs are covered by a 90-day parts-and-labor warranty. If the same problem comes back in that time, we come back and fix it.
Which brands do you service?
We work on all major brands, including Separett and Sun-Mar.
Should I repair or replace my composting toilet?
