How Long Do Sump Pumps Last?

Sump pumps protect homes from basement flooding, but they don’t last forever. Whether you’re looking into installing one for the first time or wondering if your current pump is nearing the end of its life, it’s helpful to know how long you can expect your sump pump to last. Here’s everything you need to know about sump pump lifespan differences, replacement costs, and maintenance tips.

How Long Do Sump Pumps Last?

The lifespan of a sump pump depends on its type, usage, and maintenance.

Submersible sump pumps sit inside the sump pit, becoming fully submerged when the water level rises. They are more powerful and run quieter than pedestal models, making them ideal for homes that experience frequent flooding. However, because they operate underwater and endure more wear, their lifespan is shorter—around seven to 10 years. Proper maintenance extends their longevity, but they will eventually need replacement due to repeated exposure to moisture and debris.

Pedestal sump pumps have a motor mounted above the sump pit, which keeps it out of the water. Because they stay dry, pedestal pumps typically last longer—often 10 to 15 years. They’re also easier to service since the motor is accessible. However, they’re usually less powerful, operate more loudly, and take up more space than submersible models.

How Much Is a Sump Pump?

The cost of a new sump pump depends on the type and its features. Pedestal sump pumps may cost $60 to $170. They are affordable and long-lasting but are less effective in heavy flooding situations. Submersible sump pumps range from $100 to $400. They are more efficient at handling large volumes of water but have a shorter lifespan.

Keep in mind that these prices are for the units alone. Professional installation adds to the overall cost, with labor and materials accounting for the brunt of your investment. If you’re installing a new pump and need a sump pit and discharge pipe installed, the costs will be higher than if you’re replacing an existing sump pump. On average, homeowners spend between $1,200 and $2,500 for a complete sump pump installation.

Signs You Should Replace Your Sump Pump

If your sump pump is more than seven to 10 years old, it might be time to consider a replacement. Replacing your sump pump before it fails can save you from expensive water damage and the hassle of dealing with a flooded basement. Beyond age, other signs that you need a new sump pump include:

• Frequent cycling: The pump turns on and off repeatedly, even in dry conditions.
• Loud noises: Rattling, grinding, or whining may indicate worn-out motor parts.
• Flooding: If your basement floods despite the pump having no power issues, the unit may be losing efficiency.
• Musty odor: A functioning sump pump prevents standing water and mold growth. A musty smell means excess moisture may be present, indicating the pump isn’t working.
• Visible rust: This is another red flag, as mineral buildup from water slowly eats away at the pump’s components.

How to Replace a Sump Pump

Replacing a sump pump doesn’t have to be a hassle. Here’s how the process works:

• Turn off the power: Unplug the old sump pump and, if it’s hardwired, switch off the circuit breaker. This prevents electrical shocks while working in a damp environment.
• Remove the old pump: Disconnect the discharge pipe and lift the old pump out of the sump pit. Be prepared for some water and debris in the pit, especially if the pump has stopped working.
• Clean the sump pit: Remove any sludge, debris, or buildup inside the pit. A clean sump pit allows the new pump to function properly and prevents early clogging.
• Install the new pump: Position the new sump pump in the pit so it’s sitting level. Reconnect the discharge pipe, and make sure the fittings are tight and properly sealed.
• Test the new pump: Pour water into the sump pit to check if the pump activates correctly. Ensure it removes water efficiently and that the discharge pipe doesn’t leak.

While DIY enthusiasts might feel confident tackling this project, hiring a professional is wise to ensure the job is done safely and correctly.

How to Test a Sump Pump

Regular testing is a simple way to ensure your sump pump is ready when you need it. Here’s what to do:

• Fill the sump pit: Slowly pour a large bucket of water into the pit and watch for the pump to activate. If it doesn’t turn on, double-check the power supply.
• Inspect the float switch: The float switch tells the pump when to turn on. Adjust or replace the switch if it’s stuck or obstructed.
• Check the discharge pipe: Ensure water flows freely through the discharge line and out of the house. A blocked or frozen pipe may cause the pump to overwork and fail.

How to Tell if a Sump Pump Is Working

An unreliable sump pump puts your basement at risk. Look for these signs that indicate whether it’s working properly:

• The pump turns on and off correctly: The pump should activate when the water level rises and shut off once the water is drained. There may be an issue if it runs constantly or not at all.
• Water drains efficiently: A properly functioning pump removes water from the sump pit within seconds. If the water lingers, the pump might be clogged, overwhelmed, or failing.
