Vertex rodi issue.

[hillegom]

Before you order new, check your connections.
Is the booster pump getting power?
Is the pressure sender sending the proper signal? If not, the pump will think that the psi is already high.
As mentioned take the pump off line and see if it will run, if it is getting power?
12V pump? maybe the transformer if pump does not start.
A lot of things to check before you have to spend big bucks
