Is It Time For a New Well Pump Installation?
On average, well pumps are expected to last up to 15 years. However, the actual lifespan will vary depending on water quality, sediment levels, pump type, maintenance history, and usage demands. Some pumps may need replacement much sooner.
How do you know if it’s time to install a new well pump?
- Decreased water pressure
- Strange noises coming from the unit
- Poor water quality or dirty-looking water
- Air hissing out of your faucet
- Sudden increases in electricity bills
- Frequent cycling on and off
- Intermittent water supply or inconsistent pressure
- A pump that is nearing or exceeding its expected lifespan
These are all common signs that point to well pump trouble. We recommend having your pump professionally inspected so you can determine whether repair or replacement is the most cost-effective option.
Choosing the Right Well Pump
At Guardian Plumbing and Drain our experts will help you choose the right pump for your home. Several factors must be considered when selecting a new system, including depth to the water source, household water demands, well configuration, and overall system efficiency.
Choosing the correct pump helps ensure reliable performance, proper water pressure, lower operating costs, and a longer equipment lifespan. Our team will evaluate your specific requirements and recommend options that fit your home's needs and budget.
Jet Pump or Submersible Pump?

We determine the pump type by measuring your well’s depth to water.
If your water supply is closer to the surface, typically less than 25 feet below ground, we recommend installing a shallow-well jet pump.
For water supplies 25-400 feet below, we recommend deep-well jet pumps or submersible pumps.
Submersible pumps are known for their quiet operation, efficiency, and ability to deliver water from deeper wells. Jet pumps are often easier to access for maintenance and can be a practical solution for shallower water sources.
Our team will explain the advantages of each option and help you select the system that provides the best long-term value for your property.
Determining Pump Size
Well pump sizing depends on your household’s water use. The average 3-4 bedroom house should install a pump that can supply at least 8-12 gallons per minute (GPM).
The GPM is calculated by counting the number of water fixtures (showers, sink faucets, outdoor faucets, etc.) and water-dependent appliances in your home (dishwashers, washing machines, refrigerators). That total will help estimate the flow rate your new pump should provide.
Pump sizing also takes into account well depth, pressure requirements, peak water demand periods, and future household needs. An undersized pump may struggle to keep up with demand, while an oversized pump can cycle excessively and experience premature wear.
It can seem daunting trying to figure out which pump you should install, especially if your old pump was undersized. Leave the task of choosing your new pump to us. Our team will assess your home's requirements and determine the type and size of pump that is most efficient.
Common Well Pump Problems
Well pumps can experience a variety of issues over time. Common problems include loss of water pressure, short cycling, electrical failures, worn pressure switches, clogged intake screens, sediment buildup, and aging components.
Some homeowners may also notice unusual noises, inconsistent water flow, air in water lines, or increased utility costs. Prompt diagnosis and repair can help prevent more serious system failures and restore reliable water service.
