What information must designers know regarding the sewer, water, and gas systems?

Designers must have an understanding of the actual elevation of all building floors in relation to sewer, water, and gas systems because this information is critical for ensuring proper drainage, water distribution, and gas line installation. The elevation affects how gravity influences drainage systems and helps in determining the necessary pump requirements and slope of sewer pipes. Additionally, it ensures that water supply lines are adequately pressurized and that fixtures are at the correct height to meet local plumbing codes and standards.

Proper consideration of building elevations also aids in preventing issues such as backflow or inadequate water supply due to pressure differences. Understanding elevations allows designers to effectively plan for and address potential problems related to system performance and code compliance.

While pressure ratings, types of materials, and cost estimates are essential for specific aspects of system design, knowing the actual elevation of building floors is crucial for the overall functional integrity of the plumbing systems.
