1. Sun-Mar toilets are designed so that air is constantly being drawn in and up the vent stack to create a partial vacuum.  On electric units, air is drawn in by a fan and exhausted to a 2’’ vent stack, and on non-electric units by a 4’’ vent stack that acts just like a chimney on a wood stove.
2. The patented Bio-Drum ensures a non-offensive odor aerobic breakdown of wastes.

5. Can Sun-Mar composting toilets be used in the winter?

Yes.  For limited use the unit acts as a holding tank as long as there is sufficient room in the Bio-drum.  For extended winter use, the unit must be kept warm in order for composting to continue.  This can be accomplished by taking appropriate steps to insulate and supply heat to the area with a space heater or other heat source.

6. Are Sun-Mar units easy to operate?

Yes.  Start-up is as simple as adding some peat mix bulking material called “Compost Sure” to the Bio-drum, and some special microbes called “Sun-Mar Microbe Mix.”  Enough of each product is supplied with each unit to get started.  Once you add both, you are ready to use your Sun-Mar just like a regular toilet, even using regular toilet paper.  To keep it going, just add one cupful of Peat Mix per person per day and rotate the drum using the recessed handle 4-6 complete revolutions every 2-3 days.  For weekend use, just rotate the drum before you leave at the end of the weekend.  Removing the compost is quick and easy and is only required once or twice a year in most applications.  Best of all, you never have to come in contact with any fresh waste material.
