Snappy Trap Double Sink Installation Manual

Installing a double sink with snappy trap is a complex process, especially when dealing with local building codes and inspector requirements. As a homeowner or DIY enthusiast, it's essential to follow the correct procedures to ensure compliance and avoid potential issues.

The article begins by highlighting the challenges faced by the author in designing their first installation. They realize that their initial design would fail due to S-traps, which are indeed a common issue in plumbing systems. However, the local building code in Pittsburgh requires two Air Admittance Valves (AAVs) for double sink installations.

The article then delves into the complexities of installing AAVs and sanitary crosses. The author is concerned about meeting the inspector's requirements, specifically regarding the installation of AAVs above sanitary crosses. They mention that their inspector explicitly stated that this setup is not legal in Pittsburgh and that separate AAVs are necessary for each bowl.

The article also explores the option of splitting the drain line into two separate lines, treating them as two individual sink installations. However, the author is unsure if this approach meets the local building code requirements.

Another key aspect discussed is the necessity of a cleanout in the installation process. The author wonders whether it's required for code compliance or merely a convenience feature. They conclude that adding the cleanout might be beneficial, considering they're already tearing apart the sink setup.

Finally, the article touches on the importance of understanding local building codes and inspectors' requirements. The author shares their personal experience with an inspector who was specific about the installation of AAVs and sanitary crosses in Pittsburgh. They emphasize the need to avoid arguments with inspectors by carefully following the code requirements.

Installing a double sink with snappy trap requires attention to detail, especially when dealing with local building codes and inspector requirements. Homeowners and DIY enthusiasts should prioritize understanding the necessary procedures to ensure compliance and avoid potential issues.
