The water pump 1 is the heart and circulatory system of your pool. It turns over the water in your pool at least once a day, pulling it through a filter to help remove debris, prevent and disrupt algae growth, and help your pool chemicals work more effectively. Without your pool pump, your pool will quickly stagnate, and become unusable, so if you have an older pump that’s not working the way it should, you’ll want to invest in a new one soon.

The average cost to install a pool water pump ranges from $700-$1,500, with the average homeowner spending around $950 to install a dual-speed pump.

Pool Water Pump Price by Type

There are several different types of pool pumps to consider, some of which may work better for specific types of pools, and others that may save you money on energy bills when running the pump. Each will have its own attributes to consider, as well as its own price range.

Pool Water Pump Price

Pool pump typeCost
Single-speed$300 - $600
Low-head$300 - $600
Medium-head$300 - $800
Dual-speed$500 - $800
Variable-speed$800 - $1,200
High-head submersible$800 - $1,200

Single-speed Pump

Single-speed pumps are the most basic kind. They operate at all times at a single speed, which means that they use a constant supply of energy. This makes them inexpensive to purchase, but costly to run, and some states have banned them for their high energy use. They have starting costs between $300 and $600 depending on size.

Dual-speed Pump

A dual speed pump has a high and low speed. This means that you can run it for longer at the lower speed, using less energy, then turn it to high speed when vacuuming or when you need faster turnover. They can save you energy and money, but need to be manually set to which speed you would want. Some models come with remote controls for this, others need to be set at the pump. They have starting costs between $500 and $800 depending on the size.

Variable-speed Pump

A variable-speed pump works differently than the other pumps, using the same magnetic motor that a car uses. It costs more upfront, but uses far less energy than the other types, saving you a lot of money each month. They’re much quieter to use than the other models and can give you a much faster turn over your water with less energy used. They cost between $800 and $1,200 on average.

Low-head Pump

A low-head pump is meant to be used in conjunction with a waterfall or another water feature that turns water over very quickly. It is not meant to filter the water or to be used with a filter but can help with high flow situations. They have starting costs between $300 and $500 on average.

Medium Head Pump

Medium-head pumps are what most people use in their pools. They work with most plumbing, and this is the most common type of pump. If you have a regular in-ground or above-ground pool, this is the type of pump you’ll use. They have an average cost range between $300 and $800.

Many people today are creating more complex pools with slides, spas, and other features. These types of pools need more water turnover, and thus require a high-head pump, which uses a 3-inch pipe (unlike the standard 1-½-inch pipe) to circulate the water. They’re expensive, but necessary if your pool has a lot of water features on it. Most pools will not require this type of pump, however. They have starting costs between $800 and $1,200.

Consult with a pro when installing your swimming pool water pump

Solar Pool Water Pump Cost

Solar pool pumps operate similarly to other pool pumps. They circulate the water in the pool, turning it over so that you don’t need to worry about algae growth or debris collecting in the pool. The difference is that a solar pump relies completely on solar energy to operate, rather than electricity from a grid. This means that there are no operating costs associated with a solar pool pump once it’s been installed. The solar pump may be added to a solar heater, or it can be installed independently.

Solar-powered pool pumps have starting costs around $500, and can go as high as $2,000 depending on the size of the pump and any features you may desire it to have. Installation costs are often higher than with a standard pump, however, with costs starting closer to $400 in installation fees, and going up depending on where you will install the panels. So ultimately, this style will typically cost more than similarly sized standard pool pumps, but they pay for themselves over time, and many areas have rebates and credits available to help offset the initial cost.

How Do Pool Water Pumps Work?

Pool water pumps are made up of three general pieces. The housing, which includes the filter, the inverter, which pushes the water through the filter, and the motor, which is what turns the inverter.

When your pump is operational, the motor turns the inverter, which pulls water up out of the pool and through the filter, where it is recirculated back into your pool. Pumps can be run for as few as 8 hours a day, with 16 hours of stagnant pool use, or they can be run continuously for 24 hours, depending on the type of pump you have. The more your pump runs, the less chance that things like algae and bacteria will have a chance to grow. However, with single-, and even dual-speed pumps, running your pump 24 hours a day can have high costs. Variable speed pumps, which are very energy efficient and quiet, can often be used for the full 24 hours, rather than allowing the pool to remain stagnant for periods of time.

Labor Costs to Install a Pool Water Pump

Pool pumps are most commonly installed by pool service professionals. Pumps may be hardwired or plugged in and may take 120v or 240v circuits, depending on the pump, which can impact the installation process and installation costs.

Most pool service professionals charge by the project, with different costs for new installations, replacements of the same kind, and replacements of a new kind of pump. For example, new installations and installing a different kind of pump than what had been there previously have costs around $280 to $350 for the project, while replacing an existing pump with the same model and style has a cost closer to $200. Most people pay around $300 for labor on a pool pump installation, out of the $950 total.

Water pump installed in an above ground pool

Installation is generally straightforward. The pump sits in a well beside the pool and is connected via a series of PVC couplings and pipes to allow for the water to be pulled through the filter and back out into the pool. The pump is first hardwired into the electrical supply, then connected to the pipes, and seated in its well. Some replacements may mean also replacing the pipes and connectors to fit for size, which is why there is a higher installation cost for different pumps when making a replacement.

Pool Water Pump Cost Factors

There are many factors that can influence the cost of your pool pump. Pumps come in not only different motor types, which can influence the cost, but they also come in different sizes. A pump that has a 1/2 HP motor, is going to be less expensive than a pump with a 3 HP motor. The motor size is directly tied to the size of your pool, so larger pools will have higher related costs.

Other cost factors include the type and kind of installation, as well as whether this a replacement or new installation. A direct replacement of the same type and brand of pump is going to cost less than replacement with a new type and brand of pump. New installations are typically done at the same time as the pool is built and are factored into the total expense of the pool, including the plumbing and electrical, but if these things are done piecemeal, or if you’re not working with a pool service company to oversee everything, then you may need to pay an additional $700 to $1,000 in electrical fees as well as an additional $1,000 to $2,000 in plumbing costs. These are most often rolled into the pool setup costs, but not always, and you should always check with your pool installer to find out if you will have additional costs for installing the pump.

How to Choose the Perfect Pump for Your Pool

The pump that you choose is going to be impacted by several things, such as the size of the pool, the type, what features you have, and how often you want to run the pump.

Above Ground Pool

Most pumps can be used with both inground and above-ground pools, but some smaller above-ground pools can use pumps designed just for them. The key is to make sure you get the right sized pump, but you can use any medium-head pump with a single, dual, or variable speed motor.

Inground Pool

With the exception of some very small pumps specially made for above ground pools, you can use nearly any type of pump in a standard inground pool, provided it’s sized properly. For basic pools, use a medium-head pump. For the best amount of water turn over, look for a dual- or variable-speed pump.


If your pool has a spa, or you have a spa adjacent, you will need a high-head or high-efficiency pump. You may also need to upgrade your plumbing to a larger size to handle the flow, and make sure that you size the pump to the size of the spa or pool.

Waterfall/water Feature

If you have installed a water feature on your pool, it will need its own pump for circulation. This is a low-head pump, which is designed to handle a lot of water very fast because it isn’t pushing it through a filter. You cannot use this type of pump by itself; you will need to couple this pump with another pump to filter your pool as the low-head pump works for the water feature alone.

Pool Water Pump Sizing

Pool pumps can only be effective if they are properly sized for your pool. This means estimating the number of gallons of water per minute that your pump needs to turn over in order to cycle all of the water in your pool at least once in a 24 hour period. You do this by using a basic formula:

First, determine the number of gallons of water in your pool. You should do this by taking measurements of length, width, and depth, but the below chart can give you an approximate idea:

Size of poolNumber of gallonsHP needed
15-foot round5,800¼ HP
18-foot round8,300¼ HP
20-foot round10,200

¼ HP

1 HP

1-½ HP

18 x 36 rectangle24,300


1-½ HP

20 x 40 rectangle30,0001/1-½ HP

Once you have the number of gallons in your pool, you multiply this number by 2, as you ideally want the water turned over twice in a 24 hour period. Divide this number by 24 to get the gallons per hour. Divide this number by 60 to get the gallons per minute - which is what most pumps are sized by.

For example, a 20 x 40 rectangular pool has 30,000 gallons. Multiplied by two, this gives you 60,000 gallons. Divided by 24 is 2,500 GPH. Divided by 60 is 41.67 gallons per minute, round up to the nearest size to find the right size pump for your pool, in this case, the pool would require 1 HP to filter. Keep in mind, though, that your plumbing and how large your pipes are will impact the total size. You could need a larger or smaller pump, so you should always look at what you currently have if replacing, or speak to your pool service company.

While many pumps are available in 2HP and 3HP sizes, this is often unnecessarily large and will result in faster burn out and higher energy costs than are truly needed. You may only need a pump this size if your pool is exceptionally large or deep, or has a number of added features.

Pool Water Pump Replacement Cost

The cost to replace a pool pump can vary a lot depending on the type of replacement. If you are using the same size pump, from the same brand, with the same type of motor, you can expect to pay under $200 in labor fees, plus the pump.

However, many people find that their existing pump is too large, costing them too much in energy costs, or they may want to upgrade to a variable-speed pump to save even more. If this is the case, then your installer may need to make modifications such as changing out the pipes or couplings, or they may need to rewire the area. For this reason, the fees are usually higher, around $280-$320 in labor if you are replacing the pump with a different model or type than what you currently have.

Water Pump Motor Replacement

There are times when the bulk of your pump is in good condition, it’s sized properly to your pool, and you don’t plan to upgrade to a different type. If this is the case, then you can sometimes switch out the motor for a replacement, which can save you a few hundred dollars on average.

If your pump is making noise, straining, or not able to keep up with your pool’s circulation, but it turns on and off, the inverter is in good shape, the filter is replaced regularly, and the housing is in good condition, you may be able to replace just the motor. New motors can cost from $100 - $500, and labor fees are usually lower as well, closer to $150 to replace just the motor if everything else is in good shape.

Keep in mind that if your pump is oversized for your pool it can cause the motor to wear out faster, as well as resulting in higher energy bills. If this is the case, simply replacing the motor isn’t always the best choice. Speak to your pool service provider about the size and condition of your existing pump before you choose to replace the motor to make sure that this is the right course of action for you.

Enhancement and Improvement Costs

Pool Filter Installation

Your pump and filter should ideally be housed and installed together. However, if you need to change the filter separately, you can do so for around $1,000.

Timer Installation

If you don’t want to run your pump continuously, and you don’t want to worry about turning it on and off manually, you can install a timer. They cost around $50, and hook right up to the side of the pump.

Pool Cover Installation

One way to keep your pool clean and reduce debris when not in use is to have a cover installed. There are many kinds including mesh and solid, and they cost between $2,700 and $3,700 installed.

Additional Considerations and Costs

  • Regular pool maintenance, which includes opening and closing your pool properly, can help prolong the life of your pump.
  • Sometimes your pool pump may be able to be repaired for less than the cost of replacement. Speak to your pool service company; most repairs can be done for under $200.
  • If you are replacing a pool pump of the same type and size, you may be able to do this project DIY. Make sure you shut off the electricity at the breaker before beginning. Remove the cover and disconnect the old pump, lift it up and disconnect the wiring. You’ll put the new pump in in the reverse order; wire it in first, then lower it down and connect the plumbing.
  • Energy Star rated pumps are available. These are usually variable speed motor pumps that use less energy overall, so you can save. If you purchase these pumps there may be rebates or credits available to offset the cost.


  • How much does it cost to install a pool pump?

There is a range of costs associated with installing a new pump, but the average project costs around $950.

  • How do you install a new pool pump?

The old pump is disconnected from the plumbing, lifted out, and the wires removed. The new pump is installed in reverse order, wiring it, setting it in place, and connecting the plumbing.

  • How long should pool pumps last?

Well-maintained, they should last at least 8 - 10 years.

  • How much is a 1 HP pool pump?

Depending on the type and brand, this could cost $500 - $1,200.

  • How do you know if your pool pump is bad?

Pool pumps that are going bad may make excessive noise, stop circulating water with force, or you may notice it gets harder to maintain your pool’s clarity and chemical balance.
