New sump pump cost considerations.

There are a lot of factors that go into determining the cost of your sump pump replacement. Here are some of the elements that can have an impact on the cost of this project:

Type of sump pump.

The type of sump pump you choose will naturally impact the cost. There are several different types of sump pumps available today, including pedestal pumps and submersible sump pumps.

Submersible pumps are typically more expensive. However, it may be worth the extra cost. Submersible sump pumps tend to be quieter, more powerful, and less likely to overheat compared to pedestal pumps.

Pump capacity.

The capacity of the sump pump, measured in gallons per hour (GPH) or gallons per minute (GPM), can affect the price. A higher-capacity pump will usually be more expensive. 


When comparing sump pumps, you may notice that they often come in cast iron, plastic, or stainless steel. Stainless steel sump pumps tend to be more expensive.

Here's a quick overview of the pros and cons of all three material options:

  • Plastic is usually less expensive than the other two options. It can still be durable, but not as durable as cast iron and/or stainless steel.
  • Cast iron does a good job dissipating heat to the water to avoid overheating the motor, which may help your sump pump last longer.
  • Stainless steel/cast iron sump pumps are on the more expensive side. However, they have good heat dissipation and are resistant to corrosion.

If you need help deciding on what type to get, don't hesitate to consult your contractor.

Quality and brand.

Higher-quality sump pumps from reputable brands may cost more but can offer better reliability and performance. Cheaper options may save money upfront but require more frequent replacement.

Do your research and compare the best sump pumps on the market.

Project complexity.

Several details can make this project more complicated, which may increase the cost. For example, where your sump pump sits is a factor to consider. If the sump pit is hard to access, for example, the installation cost may be higher.

Does your project require additional plumbing or electrical work? This may also increase the cost and time it takes to complete the project.

What you need to know before buying a sump pump.

Before purchasing a sump pump, there are a few considerations to keep in mind. 

The first is your home’s specific needs. Is your property vulnerable to flood and water damage? How high do water levels rise in your area? How large is the basement or crawlspace that’s most at risk?

This information will help you determine the appropriate pump capacity. It will also help you decide whether you should opt for a submersible or pedestal pump to help prevent flooding.

From there, do your research to ensure you’re investing in a quality brand. Reliability is essential when dealing with water emergencies.

Lastly, if you’re worried about the potential flood risks in your area, consider a backup system to safeguard against power outages or pump failure. Pumps that work with a backup system can help provide much-needed peace of mind.

Tips for saving money on sump pump replacement.

When the time comes to replace your sump, consider the following tips:

  • Carefully assess your needs to avoid over-investing in a pump with excessive capacity.
  • Opt for a reliable, mid-range pump from a reputable brand rather than the most expensive option. As long as the brand offers good customer service, this is a great way to balance cost and quality.
  • Consider handling the installation yourself, but only if you’re well-versed in the plumbing skills needed to complete the job.
  • Keep an eye out for promotions or discounts offered by manufacturers or local suppliers.
  • Don't skip regular sump pump maintenance, as preventive care can extend your pump's lifespan and save you from having to make costly repairs.

By making informed choices and finding small ways to cut costs, you can replace your sump pump without breaking the bank.

Sump pump maintenance considerations. 

Do sump pumps need maintenance? Yes, sump pumps do require regular maintenance. This can help extend the pump's lifespan and, in some situations, ensure it remains within the manufacturer’s warranty.

Proper maintenance can also prevent clogs, blockages, and mechanical issues that might lead to a malfunction during heavy rain or flooding — precisely when you need the pump most.

Routine maintenance typically involves:

  • Checking the pump for debris
  • Ensuring the float switch operates correctly
  • Cleaning the sump basin.

It's also essential to test the pump periodically to ensure it activates and pumps water as expected. During this test, inspect the discharge pipe, and check the valves for any clogs or obstructions.

Make sure to check the pump’s manual before you begin any cleaning, repair, or maintenance tasks.

Cost of DIY vs. hiring a pro to install your new sump pump.

While some homeowners may choose to replace their sump pump themselves, manufacturers typically recommend professional installation (and repairs). This helps ensure safety and reliability. 

It may cost more to hire someone, but a pro's skills, experience, and expert knowledge are essential to ensure your pump works correctly.

Search local plumbers and check prices.

Who is the best person to install a sump pump?

If you’ve decided to hire a professional, the best person to install your new sump pump is typically a plumber or a waterproofing contractor with experience in sump pump installation.

These experts have the necessary expertise to assess your home's needs. They can also help you choose the right pump and install it so it works effectively. This type of professional installation reduces the risk of errors and potential flooding due to improper setup. 

Is it worth replacing my sump pump?

If you’ve yet to use your sump pump, it can be hard to tell whether it needs to be replaced. However, if your current sump pump is malfunctioning, unreliable, or unable to handle the water volume in your basement, consider replacing it.

Replacement is essential to protect your basement floor or crawlspace from potential flooding. A reliable, effective sump pump provides ongoing peace of mind and reduces the risk of water damage to your home.

Regular maintenance and monitoring can help extend a sump pump's lifespan. But if it's beyond repair, it's best to replace it.

Let's put it this way: The potential cost of water damage and the massive inconvenience of a flooded basement will likely always be higher than the cost of installing a new sump pump. Investing in a good one is a small price to pay for peace of mind.

How many years does a sump pump last?

Typically, sump pumps last at least 7 years with proper maintenance. However, factors like usage frequency, power outages, and overall care can influence its lifespan. Inspecting it regularly and replacing it when necessary can help ensure it functions well when needed. 

How long does it take to replace a sump pump?

The time it takes to replace a sump pump depends on many factors, such as: 

  • Accessibility 
  • Installation complexity
  • Any plumbing or electrical adjustments needed 
  • Technician availability 

Generally, a skilled sump pump contractor can complete the replacement within a few hours. However, if the rainy season is approaching, you may be competing with others to secure an appointment. 

Does insurance cover a failed sump pump?

Insurance coverage for a failed sump pump varies. Most standard homeowners insurance excludes water damage from sump pump failures. Flood insurance may also exclude it. Instead, you may need to look into buying water backup or sump pump failure coverage options from your insurance company and add it on.

Make sure you review your policy carefully to ensure you know what type of sump-related damage it covers and do everything possible to keep your pump well-maintained and under warranty. 

Can a sump pump be installed in an older home?

Yes, you can install a sump pump in an older home. If your older home doesn't already have a sump pump, it may be vulnerable to flooding. Adding a sump pump is a protective measure that can help ensure your home remains in great shape for many years to come.
