Outlet (Waste Trap Configurations)

A toilet is S-trap or P-trap based on which way the waste pipe comes out.

  • S Trap: Common in Australia—on an S-trap pan, the toilet outlet connects straight to the floor.

  • P Trap: On a P-trap pan, the toilet outlet connects directly to the wall.

  • Universal Trap: The pan can be fitted as either an S trap or a P trap.
