is it allowed to drain sanitary sewer into sump pit
In all cases the codes strictly prohibit discharging a sump pump into a sanitary drain. One key indicator as to whether your floor drain is connected to a sanitary sewer or a storm sewer is the presence of a P=trap under the floor drain opening.n the other hand, in some jurisdictions they say that a basement floor drain is primarily intended to discharge storm runoff water that may enter the basement and the codes strictly prohibit discharging storm water into a sanitary drainage system therefore the floor drains must discharge into a sump pit.
