What to do if your water pump has a short wire?
Take a look at the fittings, wiring, and water piping involved. Watch out: fatal shock hazards are present. Leave the circuit off until an electrician finds the short or the wires are replaced. My submersible pump shows power supply through two wires when one is connected to power supply.
How to adjust the pressure of a well pump?
ADJUST PUMP PRESSURE CONTROL. , see WATER PRESSURE FALLS SLOWLY, ERRATIC PUMP: bad pressure control switch, building water running or leak, bad pressure gauge, bad check valve, bad foot valve. at SIGNS OF AIR LOSS. At WATER TANK AIR, HOW TO ADD we discuss adding the right amount of air to a non-bladder steel or glass-lined well tank.
What does abnormal resistance on water pump wire mean?
Abnormal resistance on pump circuit wires (with POWER OFF so we don’t get fried) an indicate a shorted or grounded wire (zero or abnormally low resistance) or an open circuit (broken wire, high or infinite resistance) So we could argue that a pump running against a waterlogged pressure tank might see higher than normal pressure but I doubt it.
How can I find out what my water pump problem is?
Ultimately using some simple electrical tests the homeowner traced the water pump problems to a nicked well pump wiring circuit wire. We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need.

What kind of wire does a water pump use?
It also has red, black, green wire. the pump has no control box and the water line was cut off. green wire seems like the cap, the red is the run and the black is the start? I had it running in that manner. If i changed the red and the black the water flow was not as much. but I’m not even sure of what cap or caps i need.
What does the ground wire on a pump read?
The ground wire from the pump will read low resistance to ground. The other 2 wires are the pump leads. Neither of the pump leads should read much continuity to ground, but will register a hundred ohms or so between each wire. That is the motor winding. The pump is AC so you cannot make it run backwards by reversing the leads.
Can a loose wire cause a water pump to stop working?
A loose wire can cause intermittent pump or other electrical device failures as well as a hard failure that means no power or blown fuses. Adjust or replace the pressure control switch. Temporary emergency repair by cleaning the switch contacts may be possible. A bad impeller can jam the pump, causing it to draw high current.
