Installing a Single Bowl PVC P-Trap

Project Overview

Installing a Single Bowl PVC P-Trap

Drains in the Canada must a P-trap. The trap is a safety device to prevent noxious gases from entering the house through the sewer. Sewer gases are a health hazard and can also be explosive. A P-trap captures standing water in the curved portion of the trap to prevent sewer gas from leaking into the room. When the drain is used, the trap is replaced with fresh water. Over time, solids adhere to the trap, perhaps clogging the drain or even damaging the trap. A damaged trap must be replaced.
