Issue with CP3 pump and lift pump.

[DetailsUnlimited]

Has anyone had any issues with a cp3 pump making noises when your lift pump is on? When I turn it off it goes away. Is the cp3 pump or regulator going out or is this normal?

The pressure going into the CP3 should not be more than 15 PSI. It sounds like yours is set too high or your return line back to the tank from your feed pump is restricted.

I just ran all new return lines from both pumps into a T. The lift pump psi was high, I cut the spring down and now it's at 12 psi. The LP was already turned all the way down and was still over 15psi. Worked fine until I took the big pump out of the valley and put it up top. I will go back and pull the return lines to see if there is a restriction.
