Customer Questions & Answers

Waste Line Length?

Does this unit have to be installed directly under suggested toilet? This unit is to be installed @ hunting cabin. If a 4 ft waste pipe between toilet & unit could be installed it would easier to install & clean out compost.
Asked by: WaterwoodMike
15 feet or less between the bowl and the composting unit.

Can it be used in a basement and is it alright for the toilet to be on other side of a wall with the 3" pipe?

Toilet included?

I'm confused about if this includes a toilet or seat? Why is there a bowl height and color if no toilet is not included?
Asked by: daver
When you purchase a central system, you are buying the central composting unit that is installed in the lower level, below the toilet. The toilet fixtures to be installed in the bathroom are sold separately.
