HydraCARDs | When printing final, your outside hose demand after the pump isn't included in the total flow. <img src="https://hydracards-storage.s3.amazonaws.com/media/public/django-summernote/2025-09-17/a028749e-2c7b-4d39-8cba-24586d7cf6a5.png" style="width: 100%;"> In the example above, the system demand is 1274 gpm is represented by point D2/D3. The outside hose adds up to another 250 gpm but there isn't another marker at 1524 gpm *Please note, while the Demand summary at the top shows D3 as a point, since D2 and D3 are the same value, the graph will only show point D2.

Description:

When printing final, your outside hose demand after the pump isn't included in the total flow.

In the example above, the system demand is 1274 gpm is represented by point D2/D3. The outside hose adds up to another 250 gpm but there isn't another marker at 1524 gpm

*Please note, while the Demand summary at the top shows D3 as a point, since D2 and D3 are the same value, the graph will only show point D2.

Solutions:

Cause:

Select the Hydraulic Graph option "Std w/Hose"

Solution:

Your graph will show the extra 250 gpm after the pressure boost caused by the pump

This is also a reminder that OUTSIDE hose taken between the PUMP and SOURCE do not count as the system demand, hence the reason it isn't part of the graph when you choose Standard.
