Why is dimensional tolerance important in plumbing prints?

Dimensional tolerance is critical in plumbing prints primarily because it ensures enough clearance for installation and maintenance. When plumbing systems are installed, there is often limited space to work within, especially in areas with multiple systems integrated together, such as behind walls or in ceilings. By specifying tolerances, the plans allow for adequate space to maneuver tools and perform routine maintenance.

These tolerances also account for variances in the materials used and any potential errors in the installation process. Without proper dimensional tolerances, components may be too tightly packed, complicating repairs or adjustments. This oversight could lead to increased costs and labor because of the difficulties encountered during installation or troubleshooting.

While other aspects such as cost and aesthetic design play roles in plumbing plans, they are secondary to the fundamental need for accessibility and functionality, which is encapsulated by the importance of dimensional tolerance.
