This is a technical specification document for public lavatory energy code compliance, specifically depicting a plumbing system design schematic compliant with N.T.S. (not to scale) standards.

The document illustrates a re-circulating hot water loop system for public lavatories utilizing KHS flow-splitter models 6510603200 and 6510604000. Key components include an integral shut-off valve with access panel above the ceiling, a reducer, and branch connections to fixtures with a maximum distance of 2 feet from the main line. The system incorporates inside wall cavity routing and is designed to minimize water volume and heat loss. Table C404.5.1 specifies piping volume and maximum piping lengths based on nominal pipe size, with volumes ranging from 0.33 to 18.0 liquid ounces per foot length, and maximum piping lengths from 4 to 43 feet depending on pipe diameter (1/4" to 2" or larger). The maximum allowable pipe volume methodology (C404.5.2) establishes compliance parameters: public lavatory faucets are limited to 2 ounces (0.06 liters) maximum, while other plumbing fixtures on plumbing appliances shall not exceed 0.5 gallons (1.89 liters). The water volume calculation accounts for fixture supply pipe termination and incorporates heat trace temperature maintenance systems as sources of heated water, ensuring energy-efficient hot water delivery in commercial plumbing installations.
