What To Know Before Choosing The Best Sump Pump For Outdoor Use?

In emergencies, sump pumps can be very useful. Many sump pumps in residential buildings are capable of transporting up to 20 gallons of water per hour. That’s a lot considering their size.

The main criteria here is to consider the volume of water that you need to drain. You can consult an expert regarding this matter. Most of the time, a 1/3 HP or 1/4 HP sump pump will suffice.

The best way to determine whether your yard drainage system is functional is to have an expert inspect it personally. Check the following things when it comes to the pump.

Pumping Capacity

Motor size options range from 1/4 HP to 1 HP, and there are also 3 HP and 3/3 HP heavy-duty motors.

However, the most important factor is the amount of water the pump can handle or push per hour. Also, you need to consider the pump’s capability to raise the water level to a certain height.

When a sump pump needs replacing, it’s a good idea to get a more powerful one this time around if it keeps running continuously regardless of the weather or time of year.

Also, the pump should be powerful enough to push water up a tall discharge pipe if your sump basin is very deep or the pump is in a deep-down location.

Pump Switch Type

Due to the switch, the sump pump is activated automatically when the level of the water rises inside the pit. In the long run, a sump pump’s longevity depends heavily on the type of switch it has.

To keep things simple for you, use the switch that comes with your submersible pump. During operation, you need to make sure the switch enables the pump to push out as much water as possible.

Additionally, the pump should be able to be powered down for an adequate time so that the unit can cool completely.
Consider the pit size or sump basin’s size when selecting a switch type. Switches should move freely in the basin without hitting the walls or hitting anything else that may cause them to become stuck.

Build Quality

On a cheap outdoor sump pump, you might be able to score a good deal. When it comes to construction quality, you could merely be wasting money if you need to replace it after a single use.

Plastic and cast metal housings are common in most models, while stainless steel housing is typically found on more expensive models.

The motor must be adequately protected, so keep that in mind. Most submersible units will have a thermally protected pump. This way, the pump will stay cool because of the surrounding water.

Portable Or Submersible?

Choosing a sump pump for your yard comes with a lot of considerations. Choosing between a submersible and portable unit is one of the most significant decisions. There are two main differences between both pumps: the way the water is drawn and the size of the water well.

A check valve collects and disperses water effectively in both drainage systems. The submersible pump is the better choice because it is quieter, lasts longer, and is also more expensive compared to portable utility pumps.

How To Install A Sump Pump Outside?

To install the right sump pump for your home’s drainage system, you will first need to select the right model and then figure out where to direct the pump’s water flow.

Installing it correctly is the most important part. You will have to do some digging and check your building code to see if there are any wires or lines underground.

As for the installation part, there are two ways you can go about this. You can either do it yourself or hire a professional drainage installer company.

Here is a step-by-step installation guide.

  1. First of all, you will need to find the lowest point in your yard where the water stands still after a storm. This is where you will need to put the sump basin.
  2. After that, you will need to install the discharge pipe and the check valve. To do that, first, locate the sewer line.
  3. Now start digging. You will need to dig deep enough to put the sump basin properly. It should also be the lowest spot in your yard.
  4. At this point, you will have to run your electrical wires and place the discharge pipes as well as the sump pump.
  5. Now attach the drainage pipe and the run pipe along the yard to a safe location. You will have to do a lot of digging and bury the pipe with clear gravel and dirt.
  6. After that, do a test run. Make sure everything is working properly.


  • Although sump pump drain systems can be connected to a storm sewer, you should avoid connecting them to a sanitary sewer for obvious health reasons.
  • If standing water collects in your yard, direct it toward a storm drain or a low part on the street. In order to prevent sewage water from getting back up from the storm sewer, you should choose a system that is equipped with an anti-siphon device.
  • It is recommended that you direct water away from the exterior of your home by at least 10 feet to prevent water from pooling around your foundation.
  • Another concern is electric shock. GFCI outlets should always be installed. These outlets are designed to prevent shocks thanks to the ground fault circuit interrupters (GFCIs).
  • Avoid plugging your power cord into a regular outlet or extension cable, so you don’t risk getting shocked.

How Do I Keep My Outside Sump Pump From Freezing?

Although these sump pumps are designed to be located outdoors, you will need to take extra precautions if you live in a climate that freezes.

In order to prevent the water and pump from freezing, you will need to prevent cold air from getting into the pit. You would have to ensure that freezing air cannot reach that depth of soil, but it is well above freezing at that depth.

Here are common prevention methods that you can apply that will help keep your outside sump pump from freezing.

  1. If you have an airtight cover for your pit, make sure it’s well-insulated. In the event of a water freeze, the pump is almost certain to crack. It is also more challenging to test or service a pump that is outside.
  2. It is impossible for your pump to push out water through frozen drains. Pour hot water down all drains and sewer lines to prevent them from freezing shut.
  3. Keep ice away from your pump to warm it up. Snow and ice can be removed from the pump basin with a small shovel or even your hands.
  4. It is a good idea to keep the pump in your garage during a blizzard. The water near the surface will freeze when the weather is below freezing, so you won’t have to worry about draining the yard.
  5. When it becomes cold, the water at the bottom of your exterior pit could freeze. If your pump is surrounded by water that can turn into ice, then your pump is at greater risk. Before the cold weather sets in, remove as much standing water as possible.
  6. Covering the pump with a sheet is a simple way to prevent damage and prevent it from freezing. Even though it might not seem like a big deal, it is worth having.
  7. Sheets and blankets may not be enough to protect your sump pump from heavy snowfall. With a camping tarp covering the basin, you will ensure that the backyard drainage system remains operational as the snow melts.

Final Words for Outdoor Sump Pump

As you see, there are different types of exterior sump pumps for various uses. However, if you truly want to get your hands on the best outdoor sump pump, first, you will need to figure out what you want to accomplish with that pump.

If you are looking for a permanent solution, it’s better to consult with a professional drainage installer company and get their recommendations first. If you want to do it on your own, these sump pumps should be able to do the job.
