Waste Pipe Installation

The diagram below illustrates acceptable slopes for installation of the waste pipe.

Wastepipe Slopes

When installing the waste piping from the toilet to the composting unit, the following considerations should be kept in mind:

  1. The piping should be either 45 degrees or more to the vertical, and/or at a 2-3 degree angle (1/4" to 1/8" drop per foot) so that the waste travels with the liquid. Piping should not be installed at between 4 degrees and 45 degrees, as the water will run ahead of the waste.

  2. Piping should not slope upwards at any point.

  3. Connections should be snug so that waste is not encouraged to "hang up" where pipe meets connector.

  4. If the horizontal travel is longer than 15 feet, a clear-out port (a Y fitting with screw on end cap) should be installed near to the toilet to provide easy access should it ever be required. Sun-Mar does not recommend an installation over 20 feet, as clogging will occur.

  5. Use a soft sealant such as silicone for the connection of the waste piping to the composting unit so that the composting unit can be moved for servicing or other reasons should this ever be required.

  6. Insulate piping if unit is to be used during the winter. For heavy winter use, the composting unit will need to be kept warm by enclosing it, insulating the enclosure, and providing some heat source. The enclosure must not be airtight since the unit must be able to draw air in.

If you need to put the composter outside or underneath the building, and it is an electric model, ensure that the electricals at the base are protected from surface water, heavy weather, and/or snow melt. Many customers construct an enclosure for this purpose.

Also, ensure that the composter can drain properly into your overflow facility. If the unit is installed below grade, a pump may be required to pump the overflow liquid back to the overflow facility.
