Statistically based method for estimating peak water supply demand.

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

It simply does not work.

Text entered in the form does not appear. Calculation summary is not shown. This app is unusable. I guess it back to excel.

App not compatible with night shift/dark theme

Cannot read test when dark theme is enabled and/or night shift kicks in. I was able to read text in entry boxes in the daytime. After 8 pm when the night shift kicked in, could not read text.
