Sump Pump Cost
The average cost to install a sump pump is $1,022. Most homeowners spend between $968 and $1,466 to have a sump pump installed. Your sump pump cost will depend on a myriad of factors, which we will get to later.
Bear in mind, replacing an existing sump pump is far less expensive than installing a brand new sump pump. Oftentimes, replacement does not include digging, electrical upgrades or plumbing costs. Additionally, some homeowners replace their own sump pumps, often slashing up to $700 off the sump pump replacement cost.
Sump Pump Installation Cost Factors
Besides replacement or new installation, there are other factors that can drastically affect sump pump prices. You won’t be able to control all, but knowing each will surely help you find the right plumber for your sump pump installation job.
Type Of Sump Pump
There are two types of sump pumps: submersible and pedestal. Submersible sump pumps are more expensive because they require a special perimeter and drainage system. Submersible pumps are more powerful, so if your town sees a lot of rainfall, you may want to consider spending more for the upgraded pump.
See the full list of pros and cons for both pumps below.
Whether you’re installing or repairing your sump pump, your geographic location will affect your project cost. Just like average home prices, sump pump costs differ from city to city. Some plumbers may charge $1,500 to install a sump pump in Chicago, but only $1,000 in Milwaukee. The best way to ensure you get the best possible sump price is to get multiple quotes.
DIY Or Hire A Pro
Some sump pump projects can be done as DIY projects. When installing a brand new sump pump, most homeowners hire professional plumbers. Digging, electrical and new installation can be complicated, even for an avid DIYer.
However, if replacing an existing sump pump, many homeowners give it a go on their own. As said earlier, DIYing this job can save you up to $700 off your sump pump installation cost. Therefore, if you have the skills and wherewithal, give it a shot.
Type Of Floor
If you don’t have a sump pump currently, plumbers will have to dig through your basement floor to install a submersible sump pump. Digging through gravel, which used to be a popular flooring material, is easy. Digging through cement and concrete, not so much. Therefore, your pro will have to use a jackhammer to get through the cement. In addition to added labor, this adds to the cleanup cost as well. Therefore, if you have a concrete foundation, expect to pay more to install a new sump pump.
Sump Pump Location
Along the same lines, where you or your pro installs the pump will change the price. Submersible pumps are placed below ground level, in the basement reservoir. Pedestal pumps sit above floor level. Therefore, since they require no digging, pedestal pumps are easier and cheaper to install.
Types Of Sump Pumps
While there are only two kinds of sump pumps, the one you choose may save or ruin your finished basement. Therefore, it pays to know all advantages and disadvantages of both.
Pedestal Sump Pumps
Pedestal sump pumps are split into two pieces and utilize a standalone motor attached to a pole. It’s installed above the basement floor with a hose or inlet pipe that reaches to the bottom of the sump pit. They’re fairly inexpensive and usually last longer than submersible types. As the motor remains above the water level, it’s not susceptible to water damage. This means the motor is exposed and will be noisy during operation. However, any repairs to the motor are usually inexpensive, as the basement floor will not need to be torn up to access it. While pedestal styles are cost-efficient and very reliable, they’re generally inadequate for moving large volumes of water. Also, a pedestal pump will not keep a basement completely dry as the pump sits above floor level and is only triggered when the water reaches a certain height above the level of the floor.
Pedestal pumps typically come with a 1/3 horsepower motor and pump 35 gallons per minute. Heavy rainstorms may cause basement flooding, as this type of sump pump wouldn't have enough power to pump the water out fast enough.
Submersible Sump Pumps
Submersible pumps utilize an integrated design that combines the motor and pump inside a waterproof housing. It’s placed in the sump crock and designed to get wet. The pump is positioned at the bottom of the unit with an outlet pipe on top. A grate on the bottom keeps debris out. Once the water reaches a critical level in the hole, the submerged pump propels the water into the wastewater pipe, which drains into the municipal sewer system. As it’s placed inside the reservoir with a cover, the pump makes little noise.
Submersible pumps come in sizes up to 1/2 horsepower with a pumping capacity of 60 gallons per minute, which is faster than a pedestal type. They’re not only more expensive but also difficult to repair as access is limited inside the sump pit.
Why You Need A Working Sump Pump
Put simply, sump pumps prevent flooding. If anyone has ever experienced this horrid experience, you know the financial and mental burden it brings.
More specifically, rain gathers around your house during large storms. Massive pressure causes a build-up against the wall and sometimes, causes cracks. Sump pumps relieve that pressure. As water fills the reservoir around a submersible pump, a float activator arm or pressure sensor turns the sump pump on and moves it through a pipe away from the house. Centrifugal force triggers an impeller to spin and forces water to move out through the pipe.
While sump pumps do not 100% prevent floods, they greatly decrease your odds of paying for various plumbing repair projects.
Signs You Need A New Sump Pump
Much like a broken furnace, there are a few telltale signs that the appliance is broken. When it comes to sump pumps, if you experienced a basement flood, then your pump is either broken or can’t handle the pressure. But besides flooding, there are other signs that indicate your sump pump is on the way out.
- Noise: Sump pumps do not have many parts and when all is working correctly, you should not hear too much. If you start to hear weird noises coming from your sump pump, chances are, the impeller is bent. If so, water can’t be moved and you’ll have a flood sooner rather than later. Therefore, if your sump pump is noisy, you must consider replacement.
- Electricity: The sump pump needs power to operate. If all electric outlets in the home are working, but your sump pump is not, you probably have an electrical issue inside the sump pump. If you think this is the case, do not attempt to fix it on your own. As you know, water and electricity do not mix, so it’s safer to leave it to the pros.
Luckily, the average price to replace a sump pump is $1,022, which is much cheaper than other plumbing projects.
DIY Or Hire A Pro?
The sump pump installation cost above assumes you’re hiring a pro to install a brand new sump pump. However, if you DIY, you’ll only have to pay for the new unit (roughly $300) and necessary permits. As you can see, you can shave almost 70% off the average cost. If you’re ready for the challenge, please consult the video below:
However, digging into cement and working with electricity are two complicated tasks and should not be taken lightly. Therefore, if you’re installing a sump pump for the first time in your home, we highly recommend you find a reliable plumber in your town who has done it before.
Sump Pump Sizes
Sump pumps come in various sizes. Some basements with poor foundations require very popular pumps and some homes see very little rainfall and therefore, do not require potent pumps. To help you determine the right sump pump size, consider the following factors:
- Volume Of Water: If your area sees a lot of rainfall and snow, you’ll need a stronger sump pump.
- Pipe Design: If you have long, tall or narrow pipes with a lot of turns, you’ll need a stronger sump pump.
Of course, if you’re replacing an existing sump pump (and it worked well when in use), just replace it with a unit of the same horsepower. If not, make sure you talk to a plumber before making the big decision.
Sump Pump Maintenance
Sump pumps, especially submersible pumps, are meant to take a beating. They get engulfed with dirty water and have to fight off debris and other objects. The average lifespan of a sump pump is five to seven years. To increase that timeline, consider the following maintenance items:
- During dry periods, pour water into the pit to run a full cycle.
- Run vinegar through it to remove build-up.
- Make sure the float is unobstructed and working correctly.
- Make sure water is being pumped out.
- The battery back-up pump should be replaced every three years.
- Listen for odd motor noises if it won't shut off.
Find A Plumber
Sump pumps prevent basement flooding. If your home does flood, you’ll end up spending way more than $1,022 in drywall, carpet, plumbing, and other electrical repairs. Therefore, it pays to have a functioning sump pump.
