This article explores two rough plumbing drain methods for double bathroom sinks, along with valuable bonus tips to guide you through the process. Understanding these methods and the crucial role of local building codes will ensure a smooth and compliant bathroom renovation.
Rough Plumbing for Double Bathroom Sinks: Two Drain Setups
When installing a double bathroom sink, the rough plumbing, which refers to the drain pipes beneath the sinks, can be configured in two main ways:
Single Drain Pipe with Two Arms: This method utilizes a single drain pipe that splits into two arms, each connecting to a drainpipe from an individual sink. This is a simpler setup requiring less pipe and installation time.
Individual Drain Pipes: Here, each sink has its own dedicated drain pipe. This method is more common and may be required by your local building code.
Why Local Building Code Compliance is Essential
The video emphasizes the importance of consulting your local building department before commencing any plumbing work. Building codes vary significantly across regions and can dictate which rough plumbing method is acceptable for your bathroom.
Non-compliance with local building codes can lead to serious consequences, including:
Failed Inspections: Building inspectors may withhold approval if the plumbing fails to meet code requirements. This can significantly delay your renovation project.
Costly Repairs: Non-compliant plumbing might necessitate corrective measures, involving tearing into walls and floors to expose the pipes for reconfiguration. This can be a time-consuming and expensive endeavor.
Bonus Tips for Rough Plumbing Your Double Bathroom Sink
Consult a Licensed Plumber: While this article provides a helpful overview, plumbing projects, especially those involving drainpipes, should ideally be undertaken by a licensed plumber. They possess the expertise and experience to ensure the work adheres to local building codes and best practices.
Plan Ahead: Before starting any plumbing work, sketch out a plan for the rough plumbing layout. This plan should include the designated location for the drainpipes, vents, and P-traps (curved sections of pipe that trap water to prevent sewer gases from entering the bathroom).
Gather the Necessary Materials: Ensure you have all the required pipes, fittings, connectors, and clamps before starting the plumbing work. Having everything on hand will streamline the installation process.
Consider Accessibility: Plan the pipe layout with future maintenance in mind. Ensure there is enough space to access the pipes in case of repairs or replacements.
