Are you thinking about checking your submersible pump with a multimeter, but aren’t sure how? Well, you’ve come to the right place! In this blog post, we’ll walk you through the steps of how to do just that. So whether you’re a beginner or a pro, this guide will show you everything you need to know. Let’s get started!

Why check your submersible pump with a multimeter?

It is always a good idea to check your submersible pump before you use it. A multimeter can help you do this by measuring the electrical current flowing through the pump. This will tell you if the pump is working properly and if it is safe to use.

Multimeters are available at most hardware stores and home improvement centers.

How to properly use a multimeter to check your submersible pump

It is important to have a clear understanding of how to properly use a multimeter before attempting to check your submersible pump. A multimeter is an electronic device that measures electrical parameters such as voltage, current, and resistance.

To use a multimeter, first connect the black lead to the COM port and the red lead to the VΩma port. Next, set the dial to the correct position for measuring voltage. For most submersible pumps, you will want toset the dial to 20V.

Now, touch the black lead to the negative (-) terminal of your power source and touch the red lead to the positive (+) terminal of your power source. You should see a reading on the multimeter’s display. If you do not see a reading, double-check your connections and make sure that you are on the correct setting.

Now that you know how to properly use a multimeter, you can begin checking your submersible pump for issues. First, unplug the pump from its power source and disconnect any hoses or pipes that are connected to it. Next, locate the two wires that connect to the motor of your pump.

Use your multimeter to test for continuity between these two wires. To do this, touch one lead of your multimeter to one wire and touch the other lead of your multimeter to the other wire. If there is continuity, you will see a reading on the multimeter’s display.

If there is no continuity, this means that there is a break in one of the wires or a problem with the connection between these wires and the motor. Once you have confirmed that there is continuity between these two wires, you can plug the pump back in and turn it on.

If it does not turn on or if it does not operate properly, this may indicate a problem with either the motor or another component of your pump

What readings you should expect to see when checking your submersible pump

To check whether your submersible pump is working properly, you’ll need a digital multimeter. You can get one for less than $20 at most hardware stores.

First, make sure that the power is off to the pump. Then, remove the cap from the top of the pump and disconnect the two wires that go to the motor. Once the wires are disconnected, use your multimeter to check for continuity between the two wires. If there is continuity, then the motor is good and you can reassemble the pump. If there is no continuity, then the motor is bad and will need to be replaced.

Troubleshooting tips for when your multimeter readings aren’t what you expect

If you’re troubleshooting a submersible pump with a multimeter, there are a few things you can do to make sure you’re getting accurate readings. First, be sure that the probe lead tips are clean and free of debris. Next, check to see that the probes are properly connected to the multimeter. Finally, make sure that the multimeter is turned on and set to the proper range.

How to interpret your multimeter readings when checking your submersible pump

To check for power at the submersible pump control box, set your multimeter to the volts AC setting, and touch one probe to each of the top two terminals in the control box. You should get a reading of around 115 volts if the pump is turned on. If you don’t get a reading, or if you get a very low reading, check your main circuit breaker or fuse box to make sure the breaker or fuse controlling the submersible pump circuit hasn’t tripped or blown.

Next, touch one probe to each of the bottom two terminals in the control box. You should get a reading of around 115 volts if the pump is turned on and pumping water. If you don’t get a reading, or if you get a very low reading, there may be a problem with the submersible pump itself.

Other things to keep in mind when checking your submersible pump with a multimeter

If your submersible pump is three-wire, make sure you check the continuity of the third wire as well. This is typically a green wire and is used as a ground. You should also check the continuity of the pump’s power cord from the pump to the outlet. If there is any damage to the cord, this could be a potential fire hazard.

Frequently asked questions about checking submersible pumps with multimeters

Q: Can submersible pumps be checked with multimeters?

A: Yes, multimeters can be used to check the continuity of submersible pumps. Pumps that are not working properly will show a high resistance on the multimeter.

A final word on checking your submersible pump with a multimeter

As with any electrical device, it’s always a good idea to consult an expert before attempting to check or repair your submersible pump with a multimeter. If you’re not confident in your abilities, or if you don’t have the right tools for the job, it’s best to leave it to a professional. With that said, checking your submersible pump with a multimeter is a relatively simple process that can be done without too much trouble. Just be sure to take all the necessary safety precautions and follow the instructions carefully.
