About this app

The WDC results in more accurately sized systems consistent with the lower flow rates and consumption values from water-efficient plumbing fixtures and appliances. The WDC is designed to predict peak flow rates that would impose a demand load on any portion of the indoor water supply system including the building supply, main branches and risers, and fixture supply branches. Special Features include: · Preset list of Plumbing Fixtures · Drop down menus to add the number of fixtures · Can adjust flow rates lower than the preset values · Other fixtures not listed can be added · Three units of measure can be selected – GPM, LPM, and LPS · Calculates the peak water demand · Save feature allows sending results to an email, or download to your device · History page allows you to return to projects saved
