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 main parts of a one-line jet pump well installation. Readers of this document should also see our other diagnostic guides for water pumps, wells, motors, in table form:
See WATER PUMP, ONE LINE JET for a description of the function of each component of a one-line jet pump system. Readers should also see IDENTIFY WELL PUMP TANK COMPONENTS. Nearly all well pumping systems, one line jet pump, two line jet pump, or submersible well pump, require a foot valve installed at the bottom of the well piping. If your building has water pressure problems, see WELL WATER PRESSURE DIAGNOSIS. Readers whose wells simply run out of water should also see How to Test Well Water Quantity and see How to Get More Water From a Well.
What happens when you turn on the water at a faucet in a building whose water is supplied by a one-line jet pump? (See the sketch at the top of This article for the basic components of a one-line jet pump system.) Our photograph (left) shows a one-line jet pump installed in a home.
Notice that there is a horizontal pipe with a check valve? That's the pipe leading to the water source. (We explain this check valve at WELL PIPING CHECK VALVES.)
The vertical pipe rising from the pump is the jet pump outlet connection that sends pressurized water to the water pressure tank and onwards to the rest of the building.
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.
For our complete water pressure and pump, well, and piping problems diagnostic article list, see WATER PRESSURE REPAIR GUIDE & COSTS and WATER PRESSURE LOSS DIAGNOSIS & REPAIR. 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:
