How Long Does A Well Pump Last

How Long Does A Well Pump Last?

Well Pump Maintenance and Repair

 A well pump is a crucial component of any well system, responsible for bringing water from underground into your home. As with any mechanical device, it’s important to understand how long a well pump typically lasts, so you can prepare for replacement and avoid sudden system failures. In this blog post, we’ll explore the factors that contribute to a well pump’s lifespan and what you can do to extend its longevity.

Well Pump Lifespan

The lifespan of a well pump can vary greatly depending on several factors, including the type of well pump, its size, and how frequently it is used. Generally speaking, a submersible well pump, which is installed directly in the well, can last between 8-10 years. Jet pumps, which are located above ground, have a shorter lifespan of 5-7 years.

However, these estimates are just that – estimates. Many factors can affect the longevity of your well pump, so it’s important to regularly monitor and maintain your well pump system to catch issues before they become major problems.

Factors Affecting Lifespan

1. Quality of Installation

The quality of the initial pump installation can greatly affect the lifespan of the pump. A well pump installed by a licensed professional who follows all manufacturer instructions and safety guidelines is more likely to last longer than one that is not properly installed.

2. Water Quality

The quality of the water being pumped can also affect the life of the well pump. If the water contains high levels of minerals or sediment, it can cause premature wear and tear on the pump parts, leading to a shorter lifespan.

3. Frequency of Use

The frequency with which the pump is used can also affect its lifespan. If the pump is used frequently or continuously, it will have a shorter lifespan than a pump that is only used occasionally.

4. Maintenance and Repairs

Regular maintenance and repairs can help extend the life of your well pump. Filters should be cleaned or replaced regularly to prevent sediment buildup, which can cause pump failure. General maintenance may include inspection of wiring, checking the pressure switch, and replacing worn parts.

Signs Your Well Pump May Need Replacing

As your well pump ages, you may begin to notice signs that it needs to be replaced. Some of the most common signs include:

1. Decreased Water Pressure

If you begin to notice a significant drop in water pressure in your home, it could be a sign of a failing well pump. A decrease in pressure could mean that the pump is not functioning properly and needs to be replaced.

2. Strange Noises

If you hear strange noises coming from your well pump, such as grinding, groaning or squeaking, it’s likely time to replace the pump. These noises can indicate that the pump is struggling and may soon fail.

3. Increased Energy Bills

If you notice an unexplained increase in your energy bill, it could be a sign that the well pump is working harder to keep up with demand and therefore consuming more electricity. This could be a sign that the pump is nearing the end of its lifespan and needs to be replaced.

4. Dirty Water

If you notice that the water coming from your taps is dirty or has particles floating in it, it could be a sign that the well pump is failing and allowing sediment and debris into the water supply.

5. Sudden Loss of Water

If you suddenly lose water in your home, it’s likely that your well pump has failed and needs to be replaced. If this happens, it’s important to call a licensed plumber professional to assess the situation and replace the pump as soon as possible.


The lifespan of a well pump can vary greatly depending on several factors, including the type of pump, water quality, frequency of use, and maintenance. While most pumps have a general lifespan of 5-10 years, regularly monitoring and maintaining your system can help catch issues before they cause major problems, potentially extending the life of your pump. If you notice signs that your well pump needs replacing, it’s important to call a licensed professional to assess the situation and replace the pump as soon as possible to avoid further damage to your system.
