    For Surge questions it is often best to reach out to us at to get the best assistance with surge questions as we often need to see your specific model to address most questions quickly.

    I did reach out to one of our team members who usually support most of our surge cases and they indicated the following:

    "In Surge analysis, surge protection devices are placed on a junction. The Junction with a surge protection should have only one pipe connected to each side."

    Can you check if you have a junction with a surge device that is connected to more than two model pipes?

    In the InfoSurge User Guide (generally found here: C:\Program Files (x86)\InfoWater\Help and is called InfoSurge Users Guide.pdf) they list the following restrictions for network components when doing a surge analysis on page 2-20:

    Thank you
