This WATER PRESSURE PROBLEM DIAGNOSIS TABLE series provides a table giving step by step checklist for diagnosing water pressure, water pump, and water well problems.
We give diagnostic and repair procedures for both municipal water supply problems and well water supply problems.

Keep in mind that if water is running elsewhere in the building (another shower, sink, dishwasher, clothes washer, garden hose, etc) then the water pressure you will observe at your location will usually be reduced. This table can demonstrate that You're the boss, not your pump!
Table 2: Well Pump Runs, but Poor Water Pressure or No Water Pressure | ||
Poor Water Pressure Cause | Diagnostic Procedure | Repair Procedure |
---|---|---|
No Water at All | There is no water pressure. See the water pressure problem diagnostic steps in this table (below) or go to our diagnostic article series beginning at NO WATER PRESSURE |
See TABLE 1: PUMP WON'T RUN, WON'T STOP, or CYCLES Also
|
Poor city or municipal water pressure or flow | If municipal building water pressure varies independently of the number of fixtures you are running then the incoming pressure may be changing. Install and monitor a pressure gauge at the water meter or main water shutoff valve. If water pressure varies depending on the number of fixtures running then the incoming water pressure may be inadequate or the building piping diameter may be too small. See the diagnostic items listed in this table (below) |
MUNICIPAL WATER PRESSURE DIAGNOSIS explains how to diagnose poor municipal or community water supply quantity or pressure in complete detail Also see |
Poor private well water pressure, quantity, or flow diagnosis article | If private well water pressure, flow, or quantity vary or are inadequate See the diagnostic items listed in this table (below) |
WELL WATER PRESSURE DIAGNOSIS provides a detailed article on diagnosing poor water pressure or flow Also see WATER PRESSURE MEASUREMENT Also see WATER FLOW RATE CALCULATE or MEASURE |
Pressure gauge says low water pressure | Make an independent measurement of water pressure when the pump has reached its cut-off pressure and no water is being run in the building. A clogged or broken pressure gauge can give incorrect pressure readings and may read higher or lower than actual system water pressure. |
See WATER PRESSURE MEASUREMENT |
Water pressure comes and goes | Water pressure starts, stops, or is intermittent the problem may be in the equipment or more likely in the well itself. | See the steps in this table below. Also see WATER PRESSURE GAUGE ACCURACY |
Water Runs Out Water pressure is fine but run out of water - then none or very poor |
If water pressure seems ok for a while but sometimes you run out of water or water pressure becomes poor and weak your well may be running dry. | see WELL FLOW TEST PROCEDURE and see WELL YIELD IMPROVEMENT. |
Some of the well pump troubleshooting suggestions in this list can be found at the Betta-Flo Jet Pump Installation Manual from the National Pump Co.
