Everything You Need To Know To Find The Best Submersible Drainage Pump

Submersible water pumps work underwater and are one of the most popular types of pumps on the market today.

If you are looking for more details, kindly visit our website.

But because there are so many types of submersible pumps on the market, how do you choose a submersible pump for the correct application?

This article will show you the differences between the types of submersible pumps so you can choose exactly the type of submersible water pump you need to get the job done right.

Benefits of Submersible Water Pumps

There are many types of submersible pumps for many different applications, as explained in the next section. 

A submersible water pump's primary benefit is that it does not suffer air leaks in the pump (called pump cavitation). An added benefit of a deep well pump application is that you don't need to worry about priming the well pump because the entire pump operates underwater. Submersible water pumps are also very efficient and are not subject to overheating conditions like above-water pumps.

With the exception of submersible pumps being used for permanent applications such as a pond pump or a deep well pump, smaller submersible utility pumps are portable and lightweight as well, making the pumps extremely convenient to use in hard-to-reach places or small areas like window wells.

Types of Submersible Water Pumps

The sections below explain the uses and applications for each type of submersible water pump. Follow the links to learn more about each type of submersible pump.

Submersible Utility Pumps

Submersible utility pumps can remove standing water, empty clogged sinks, drain window wells, and much more. When choosing a utility pump, the most important factor to consider is portability. Utility pumps are best used in small spaces where other water pumps just won't fit.

The inlet size on the pump will tell you how quickly you can pump the water through the pump and discharge it elsewhere. A utility pump with a float switch (pictured below) is great too because they automate the pump by turning it on and off when water levels change, so you don't have to watch it while it works.

Urgent and semi-regular pumping applications are perfect for utility pumps, as long as the water doesn't have debris or solids in it. Utility pumps are not meant to pump solid items at all, so don't use one for cleaning dirty water with solids, and especially don't use this pump for sewage-type applications.

Submersible Trash Pumps

Another type of portable pump, submersible trash pumps are great because they are as simple to use as attaching a hose a dropping it in (but don't drop it in by the hose or power cord).

If your sump pump fails or you experience flooding with water that has a lot of sand, leaves, or other debris in it, a normal utility pump won't work-that's a job for a submersible trash pump.

Using a heavy-duty impeller, the centrifugal force shoots the water and debris out of the pump through larger inlets, hoses, and outlets than other pumps. These pumps are also more expensive than utility pumps but they are essential if you need to remove dirty water quickly in small or large areas. Because of the nature of the debris trash pumps can handle, they are usually rated for continuous duty and can easily pass sand, pebbles, leaves and more.

Pool Cover Pumps

Pool cover pumps are pretty simple to use; just attach the hose, plug it in, and set on your pool cover and watch it go. These pumps are sometimes confused with utility pumps, which makes sense because utility pumps are sometimes used for removing water from pool covers, too.

Pond and Fountain Pumps

Water features can quickly make you the envy of the neighborhood, and pond and fountain pumps make it simple and quick for your yard to stand out. Fountain pumps and pond pumps both have some surprising uses. They can also be used in aquariums, and these pumps are great for filtration or powering waterfalls and small streams around your property.

Some pond pumps come with a direct-drive dual discharge option, allowing one pump to serve two water features at once, which is easier than plumbing a separate pump for each feature. Fountain and pond pumps are usually quiet and rated for continuous duty, so they'll work for as long as they're plugged in. If you plan on using one for a pond with fish, make sure the pump is oil-free in design (almost all are oil-less).

Submersible Deep Well Pumps

Deep well submersible pumps enjoy all of the benefits listed earlier, plus have the benefit of coming with a built-in check valve to ensure system pressure and preventing backflow. Plus, because these pumps are sealed and used underwater, they are virtually maintenance-free and are made with corrosion-resistant materials.

Deep well pumps can be used in well-water applications from 15'-25' and in excess of 500' in some situations, making them the best option for wells that are narrow or deep. Just make sure to choose the proper pump size and the correct two or three-wiring option for the application.

Submersible sump pumps are the preferred choice for most residential applications, but not all pumps are made equal!

Submersible pumps come in multiple horsepower ratings and have different accessory options, and it can be confusing to choose between them.

This guide will explain everything you need to know to confidently choose the right submersible pump for your sump pit and ensure it's the right size for the job. After all, a properly sized sump pump saves money and hassle in the long run.

How to Properly Size a Submersible Sump Pump

There are four major factors to consider to be confident you're choosing the right submersible pump for the job. There's a saying about "bigger is better," but with sump pumps, this is not true.

Oversizing a sump pump can lead to constant cycling and premature burnout of your pump system. Under-sizing a pump can lead to the same issue, so it's important to choose a submersible pump that most closely fits the needs of your sump pit.

To properly size a submersible sump pump and safely put together a proper sump pump system, you'll need to:

1. Choose the right horsepower
2. Choose the right float switch
3. Choose the right water alarm
4. Choose a backup sump pump system

How to Choose the Right Horsepower (HP) for Sump Pumps

Horsepower is the most important factor when determining which sump pump is best for your application, and it's used to determine how much power your pump can produce to empty your sump pit through the discharge piping.

It's important to understand that each submersible sump pump has its own pump curve and recommended uses, so make sure to check the specifications of the pump to make sure it's going to work for you since total pump output can vary between manufacturers. This information can be found for each pump on our product pages.

If you're replacing a previous pump, typically you should stick to the same horsepower (HP) rating as your old pump unless you experienced any issues with that pump before it failed. Every sump pump has a data plate that can be checked to determine all the most important pump information, including HP ratings and model number for reference.

If you can't locate the information or can't find your user manual, we have a manual lookup tool you can use to find your old pump's manual.

1/3 HP Submersible Sump Pumps

For most average-sized homes in areas with average water tables, a 1/3 HP sump pump should be sufficient. Typically, 1/3 HP pumps can handle 7' - 10' vertical lifts from the sump pit if they have one 90-degree elbow and a horizontal pipe run between 3 feet and 25 feet.

1/2 HP Submersible Sump Pumps

If you live in an average-sized home with an above-average water table, you will most likely need a 1/2 HP sump pump. These pumps will generally pump about 35%-40% more than their 1/3 HP counterparts, and can also handle higher vertical lifts for water being pumped through your discharge pipe.

When you have a slightly higher vertical lift (10-15 feet) or a long horizontal run (example: 30-150 feet), you may notice a loss of water flow due to the increased friction from the longer runs. For those conditions, you may need a higher pumping capacity (HP and GPH) to overcome that loss.

3/4 HP - 1 HP Submersible Sump Pumps

For people living in high water table areas, flood plains, low-lying areas susceptible to flooding, or have a deeper basement, you will likely need a stronger 3/4 HP sump pump
or a 1 HP sump pump.

These pumps will generally provide a 20% - 25% increase in pumping capacity over a 1/2HP sump pump. In addition, if you have an installation where you need a high vertical lift or head (20-30 feet) and/or a long horizontal run (150-250 feet), 3/4 - 1 HP pumps provide the additional power needed to pump that water. These higher-output sump pumps are also ideal for outdoor pump applications.

When dealing with higher GPM and longer pumping distances, special attention needs to be placed on choosing a proper discharge pipe diameter to prevent problems with higher-powered pumps.

Wifi Submersible Sump Pumps and Accessories

Float switches, water alarms, and backup pumps are all necessary to prevent your basement from flooding, which is why you need a sump pump in the first place.

Most sump pumps will come with a float switch, or you can purchase a replacement separately. We recommend electronic float switches because they take up less space in your sump pit and are the most reliable switches on the market.

With water alarm systems, wifi-enabled kits can be purchased that connect to your sump pump and call, text, or you if anything is going wrong with your sump pit. They are extremely useful to have because a regular beeping water alarm won't do much good if no one is home to hear it.

Backup sump pump systems are your only hope of preventing a flood if you lose primary power at home and don't have a generator standing by. You can buy a backup sump pump system separately, or get one included with your primary pump by getting a combination sump pump system.
