Pennsylvania Statutes Title 53 P.S. Municipal and Quasi-Municipal Corporations § 4615. Subsoil drains

Subsoil drains must discharge into a sump or receiving tank, the contents of which must be lifted and discharged into the drainage system above the cellar floor by some approved method.  Where directly sewer-connected, they must be cut off from the rest of the plumbing system by a brass flap-valve on the inlet to the catch-basin, and the trap on the drain from the catch-basin must be water-supplied, as required for cellar drain.
