Could someone please tell me as to the usage of P and S traps used in the United States. I seem to have conflicting data and would appreciate if someone could enlighten me as to the percentage basis for the P and S trap toilet pipes. Cheers Mich
The S traps drains through the floor and are made with vent and without vent. The P trap drains into the wall inlet. We use P traps for fl. drs. and all kinds of drains.
