Well Pump Troubleshooting

A well pump is an important piece of equipment for those who are dependent on drawing water from wells. Problems with this device can hamper the day-to-day activities of people who use these devices every day. Starting trouble is the most common problem of well pumps. There are few other causes of this problem as well. The common problems which affect the functioning of a well pump are discussed in paragraphs below.

Starting Trouble
There are many possible causes for occurrence of problems in starting of a well pump. One should try to eliminate the possibilities one by one. This way, it becomes easy to carry out well pump troubleshooting.

• First of all, the circuit breaker and fuse need to be checked. The switch should be flipped if circuit breaker has tripped.
• The well pump motor may not start even if the voltage is not correct. The only way to troubleshoot this problem is calling the service provider.
• If impeller is not properly aligned with the motor, starting problems can arise. In such cases, one should check for high amperage and align the motor with impeller.
• The motor may not start if the wiring is damaged. Terminal connections need to be checked and inspection should be carried out for insulation of wires. Replacement of the terminal connections, wiring or both could be required in case of any damage.

Motor Doesn't Stop
Sometimes, due to the occurrence of problems in the motor, it may not stop running. Let us understand the various causes behind this problem and solutions to be undertaken.

• Improper adjustment of pressure switch is one of the common reasons behind this problem in motors. Proper adjustment of the switch solves this problems in most cases. If this measure doesn't work, the switch needs to be cleaned. Some problems are understood better by experts. Therefore, if neither of the above solutions work, expert help should be taken.
• Sometimes, it happens that a closed check wall results into the motor running continuously. Simply adjusting the check wall helps in resolving this problem.
• One of the reasons that motor doesn't stop running is broken or loose motor parts; the motor shaft can break and be one of the problems. Replacing the broken parts help in solving the problem.
• In case of submersible pumps, this problem occurs due to the intake screen getting plugged. The screen should be inspected by pulling out the pump. Cleaning it properly helps in resolving the problem.
• Well pumps that are installed above the water level, i.e. on ground are encountered by the problem of foot valve screen getting plugged. The drop pipe should be pulled in order to inspect the screen. Cleaning the foot valve screen solves the problem.

Overload is Tripped
Reasons of a condition of tipped overload could be numerous. Some of them are discussed below.

• A defective control box is one of the many reasons behind a tripped overload. The control box needs to be checked for correct voltage transfer between terminals. Replacing the box remains the only option to overcome this problem.
• The condition of tripped overload can result from overheating of the control box. Installing this box in a sunny area is the option to deal with the problem.
• If the well pump is not wired properly, problem of tripped overload can arise. The wiring diagram should be reviewed in such cases; correct wiring should be done as per the diagram.
• If the motor is placed in such a place where there is little or no ventilation, the problem of tripped overload can crop up. Air obstructions which create problems in working of the motor should be removed and if necessary the location should be changed.

Well pump troubleshooting needs understanding of the wiring and plumbing of motors. Information presented above, would help in solving the commonly occurring problems. However, for complex problems, one should consult a professional.
