What are the requirements for installing a shower trap?

The requirement for installing a shower trap is that it must be set below the shower drain and properly vented. This is essential to ensure that wastewater flows freely from the shower down into the drainage system. When the trap is installed below the drain, it facilitates the correct gravitational flow of water, minimizing the risk of backups. Proper venting is equally important as it helps to equalize pressure within the drain system, allowing for efficient drainage and preventing the trap from being siphoned dry, which could lead to unpleasant odors entering the bathroom.

Failing to meet these requirements can result in ineffective drainage and potential plumbing issues, which underscores the importance of compliance with plumbing codes and standards.
