Customer Question

We have a lake home and draw water from the lake. We have replaced the pump, pressure switch, pressure tank, shortened the line to the lake and still when having a shower and someone flushes the toilet or runs a tap the pressure goes to zero. Cannt figure out the problem

Does the pump come on when the "pressure" drops to zero? Does it actually drop to zero on the gauge?
Customer: replied 2 years ago.
No
Expert:  Rick replied 2 years ago.
No to both questions?
Customer: replied 2 years ago.
No pump does not come on and yes drops to zero
Expert:  Rick replied 2 years ago.
Did you replace all the piping around the tank and into the pressure switch? Do the contacts on the pressure switch close?
Customer: replied 2 years ago.
No didn't replace piping and contacts close
Expert:  Rick replied 2 years ago.
If the contacts close then the pump should come on. If it doesn't this is an electrical issue not a plumbing issue. Do you have a multi-meter? Have you checked voltage to the pump when the contacts are closed? Also voltage feeding the switch?
Customer: replied 2 years ago.
No, is that in the control panel? That's the only thing we have not changed.
Expert:  Rick replied 2 years ago.
I'm not sure what you mean by a control panel. Every system I have seen that draws water from a lake or something similar uses a shallow well pump not a submersible. I've never seen a control panel on a shallow well pump, only on submersibles in a very deep well. Sounds like you need to have the electrical side of your system checked out.

We have a submersible in lake. Control panel for it in house.
Expert:  Rick replied 2 years ago.
Ok, then was the control panel replaced? Has anyone checked it out? You still need to have the electrical side of the system checked out. If you have a multi-meter I can probably walk you through (some of) it.
Customer: replied 2 years ago.
Yes we have multi meter. Control panel ever changed - 19 yrs old
Expert:  Rick replied 2 years ago.
Well, Check the voltage into and out of the switch. If you have 240 v into and out of the switch along with your description I'd suspect the control panel
