Using the Water Demand Calculator in California to Right-size Plumbing in Residential Buildings

These webinars will cover the benefits of using the California Plumbing Code's Water Demand Calculator (WDC) to size plumbing in homes and apartment buildings and the impacts on water utilities.  It is a solution that reduces water aging, delivers hot water faster, generates significant construction cost savings, reduces the carbon footprint of the structure, and subsequently saves on water- and water heating-related utility bills for the entire life of the plumbing system.

Right-Sizing Plumbing in Homes and Apartment Buildings

Effective July 1, 2024, the Appendix M, Peak Water Demand Calculator (WDC) became part of the California Plumbing Code. Instead of using flow rates and flush volumes from the 1940s, the WDC will allow you to “right-size” the cold and hot water distribution systems in homes and apartment buildings using modern information about flow rates and simultaneous use. Does this sound like a snoozer? Actually, it is an environmentally responsible solution that can save energy, time, money, and water.
