How deep should the pit be for a home elevator?
Pit depth requirements vary from manufacturer to manufacturer. Some are 6″, 8″ or 12″. If you use 12″ as a standard, most manufacturers will fit. Pits can be dug to the required depth through exisisting basement floors, but when there are obstacles in the way, such as plumbing or radiant heating, a pitless elevator may be your best solution. 8.
