How to Tell if Your Well is Dry

By Hannah TaylorDecember 4, 2025

Discovering if your well has gone dry can be a daunting task, especially if you rely on it for your water supply. This guide will walk you through the process, helping you understand the signs, causes, and methods to determine if your well has indeed run dry.

Understanding Well Drying Out

Wells can dry out due to various reasons, including prolonged drought, overuse, or changes in the water table. Knowing how to identify the signs can help you address the issue promptly and prevent potential damage to your property.

Signs Your Well Has Gone Dry

Low Water Pressure: If you notice a significant drop in water pressure, it could indicate that your well is struggling to pump water.
Air in the Pipes: The presence of air in your plumbing system, often heard as a hissing sound, can signal that your well is running dry.
Pump Running Constantly: If your well pump is running non-stop, even when no water is being used, it could be a sign that it's struggling to find water.
Dry Well Casing: If you can see the well casing, check if the water level is below the casing. If it is, your well may be dry.

Checking Your Well's Water Level

Measuring the water level in your well is the most accurate way to determine if it's dry. Here's how to do it:

Remove the well cap and any debris from the top of the well.
Lower a weighted rope or a measuring tape into the well, keeping it taut to ensure it doesn't get tangled.
Mark the rope or tape at the point where it first touches the water. This is your water level.
Compare this measurement to the total depth of your well. If the water level is significantly below the bottom of your pump, your well may be dry.

Professional Well Inspection

If you're unsure about measuring the water level yourself, consider hiring a professional well driller or pump installer. They have the necessary equipment and expertise to accurately assess your well's water level and provide solutions if your well has gone dry.

What to Do If Your Well Has Gone Dry

If your well has indeed run dry, don't panic. There are steps you can take to restore your water supply:

Option	Description
Deepening the Well	If your well isn't already at the bedrock, you might be able to deepen it to reach a more reliable water source.
Relocating the Well	In some cases, it might be more cost-effective to drill a new well in a different location on your property.
Installing a Pump and Pressure Tank	If your well is still producing water but at a lower rate, installing a pump and pressure tank can help maintain consistent water pressure.

Remember, each option has its pros and cons, and the best solution will depend on your specific situation. It's always a good idea to consult with a professional before making a decision.

In the meantime, conserve water as much as possible to prevent further strain on your well. This includes fixing any leaks, using water-saving appliances, and being mindful of your water usage.
