This article describes the sequence of operating steps in a submersible well pump water system. The process of diagnosis and the costs of the repair are explained. Consumer advice on saving money on water supply repair costs includes a review of the parts and labor costs of a typical well pump and pressure tank replacement case.
Carson Dunlop's sketch at page top shows the components of a submersible well pump water supply system.

What happens when you turn on the water at a faucet in a building whose water is supplied by a submersible well pump?
The following steps describe normal operating of a building well pump and water supply system. Other cases in which the well pump controls are not working properly, there is a problem with the controls, pressure tank, pump, or well itself are discussed at WATER PRESSURE REPAIR GUIDE & COSTS and at WELL WATER PRESSURE DIAGNOSIS. Our sketch (left) shows a cutaway view of a submersible well pump.
Take a look at our well casing photograph at left. See that small gray conduit rising at the left side of the well casing? The conduit carries electrical wires into the well. That's one way to recognize that a submersible pump is installed.
When a water pump is inside the well, it can be tricky to know when the pump is actually on or off, though usually we hear the pump relay clicking, and some relays have a light that indicates that the relay is telling the pump to run.
The pressure switch calls for pumping by switching a relay in the pump relay, that actually turns the pump on and off. So a secondary potential problem would be in the relay itself, but we would look at the pump pressure control switch first.
Separately we also provide a WATER PRESSURE PROBLEM DIAGNOSIS TABLE. The following articles pertain if you have a private well, pump, and tank system for your building or if your incoming community water supply pressure and flow are just too low to start with:
