I am installing a drain pipe for 3 pedicure chairs. The each chair has a drain pump installed. The main drain pipe is 10 feet long. Does the main drain pipe have to be sloped at 1/4 inch per foot? And if so how can I make this slope with out lifting the chair 2 1/2 inches? This is a basement and the drain pipe can't be lowered. Thanks in advance.
