Button: Graphical Pressure Display Error Type: Runtime Error

Description:

While attempting to view the graphical pressure display (or water supply graph), the following error comes up.

Run-time error 9 Subscript out of range Runtime Error 9

Solutions:

Cause:

1. Order of Input Type references and locations in reference to each other.

 

2. City supply may be too low in reference to the backflow being used.
Solution:

1. In the calculation where it crashed, the user's Main piping looped back to the Riser. There are two methods to input these reference points. The Branching method or the Circular method. Branching Method of inputting reference points: A>B, B>Riser A>C C>Riser Circular Method of inputting reference points: A>B B>riser riser>C C>A The user used the Circular method to input their main. When they pressed the Graphical Pressure Display (GPD) button it crashed with the error. Once the input was rearranged to the Branching method, it worked fine.

2. City water had 10 psi residual and an RPZ backflow was being used which had a loss of ~9 psi. When another backflow was inserted, it worked. (GAB 2/19/16)
