Quaternary pump pressure reading wrong

Quaternary pump showed a wrong, non-responsive pressure reading even if no flow, how to fix it? It was used about 1.5 years ago without this problem.  Thanks.

  • Hello Ishtiyaq,

    Don't know the model of the QUAT pump but based on your description, it would appear your pressure sensor is bad.  It should read 0 at no flow and of course increase as you turn the flow on.  The other possibility is the main board but since those fail so rarely, I would go after the pressure sensor first.
