If you’ve got a water accumulation problem in your house, then you need a sump pump to remedy the situation. A sump pump makes it easy to move water away from your water-collecting sump basin to somewhere far from the house.

The advantages of sump water pumping include solving dampness issues and avoiding a flooded basement. Of course, applications can vary, but the main purpose is to pump water from a lower level to a higher level and somewhere safe.

There are different types of sump pumps, such as the pedestal and submersible pumps. As well as different manufacturers like Zoeller, Flotec, and Wayne. So, they all have their differences.

In this sump pump review, you’ll learn how to choose the right pump for the right job. Plus, you get a list of the top pumps in the market.

Superior Pump presents this top-rated sump pump that’s designed for high-efficiency water removal. It’s also the lowest priced offer on this list, making it a favorite for bargain hunters.

It comes with a 0.25-Horsepower engine and can pump water up to a height of 25 feet, at which it works at a 2 GPM (Gallons Per Minute) rate.

For shorter heights like 10 feet, it will reach pumping speeds of up to 20 GPM and its top performance lies at 30 GPM. The package includes a garden hose adapter and a manual.

The downside is its lack of an automatic control system. So you are left to switch it on and off by yourself. On the other hand, it’s very flexible and additionally available in 0.2 and 0.33-Horsepower versions.

As a submersible pump, it features a rugged and durable thermoplastic construction which provides anti-corrosion features. Superior Pump backs it with a 1-year warranty.

Pros:

• Lowest priced pump with 0.25-HP continuous-duty engine
• Lifts water up to a 25-ft height
• This pump is capable of delivering up to 30 Gallons per Minute

• Weight: 21 pounds

If you don’t mind the rather high cost, then feel free to give this heavy-duty sump pump a try. It’s made from cast iron, weighs a lot, and can handle up to 43 gallons of water per minute.

It comes with a float-activated switch to automate the control process and everything comes covered in a corrosion-resistant epoxy finish. Zoeller also uses stainless steel for the screws and switch arm to guarantee total protection from water.

How to Buy the Best Sump Pump

The unique functionality and features of a sump pump make it a unique machine that needs understanding. This is additionally important because an understanding of these aspects makes it easier for you to make the right choice.

Following are the most important aspects of a sump pump and the considerations you need to make when choosing a pump.

1. Automatic vs Manual Control

Most sump pumps you’ll find today have one type of automatic switching system or the other. This allows them to either switch themselves on automatically when there’s enough water in the sump or to switch off when there’s little to no water.

There are different technologies used for this. Most models use a float switch system to figure out water levels, while others use the more effective and costlier pressure switches. You’ll also find modern systems with more efficient or electronic control systems.

Your application may also not need an automated system and this means that you’ll either need to find a fully manual sump pump or get yourself an automatic model and break off its float switch.

2. Pedestal vs Submersible

You’ll find two major types or categories of sump pumps and these are the submersible and the pedestal types. The pedestal types such as the Flotec FPPM3600D get mounted above the water level of the sump while the submersible types get mounted below the water level.

Each of these two types has its advantages and disadvantages against over the other type, as you can see below.

• Pedestal. The main advantages of a pedestal sump pump are their lesser costs, their reduced risk of water damage, and that they are easier to repair because they stay above water.Their disadvantages include being less compact because they take up more space. They are also less powerful and their motor runs the risk of overheating after running for prolonged periods.
• Submersible. Submersible pumps are usually more powerful than pedestal types and they are less noisy as well. They are usually well-designed and their housings feature a waterproof material.On the flip side, they cost more than pedestal types because of their water-proofing and anti-corrosion properties. They are also harder to reach for service because they are often submerged.

3. Head Pressure

This is the hydraulic head pressure of the sump pump, which refers to the maximum height that the pump will push the water. In practice, you should get a pump with a head pressure that’s higher than the work you intend for it.

For example, if the total vertical height that you intend to pump the water is just 7 feet, then you need a pump with an 8-feet or more head pressure. The manufacturer will state its pump’s head pressure, so you need to look for it.

4. Horsepower & Flow Rate

These are two more terms that you really need to understand and watch out for. Horsepower refers to how powerful the engine is and this usually determines the pump’s flow rate. A 1/3-horsepower is usually enough for most homes, although more is better.

The flow rate gets measured in either GPM (Gallons Per Minute) or GPH (Gallons Per Hour), but note that it’s dependent on head pressure. So a 2,000 GPH pump could be measured at a 1-foot head, which means it might cut down to 1,500 GPH at 15 feet, for instance.

So make sure beforehand that whichever sump pump you choose can handle the job. Remember it’s better to have more horsepower and not use it than to need more horsepower and not have it.

5. Redundancy & Backups

Some sump pumps come with redundancy technologies that make them able to work even in rough times. The most popular option here is a battery that provides backup power during power outages like in a storm.

6. Cord Length

You should also consider your power outlet and your sump’s exact position, then find a sump pump with enough cable length. A second option is to use an extension cable if the pump’s cable is too short.

7. Material

Body material is only important if you are considering a submersible sump pump. This is to make sure that you get a good quality pump with a waterproof and anti-corrosion housing.

How to Install a Sump Pump

Installing a sump pump is a straightforward affair if you follow the directions properly. Following is a step by step guide that leads you through the steps necessary to install a sump pump successfully in your home.

What you’ll need:

• Electric drill and bits
• A hammer
• Gravel
• Shovel for digging
• Wire Ties
• PVC cement
• Check valves

Step 1: Diagnosis

Check to make sure first that there’s no other way to solve your basement’s water problems. One possibility is making sure that the exterior drainage is working properly. Also, make sure that your home does not include a sump already, especially if it’s a newer home.

Step 2: Location

If you decide to go ahead, then find an ideal location for the sump. It should at least be 8 inches away from the foundation and not too far from a GFCI power outlet. If you don’t have a Ground Fault Interrupter Outlet in your basement, then have it installed by an electrician.

Step 3: Dig a Hole

Once the location is decided, dig a hole for your chosen sump. You need to make the hole about 6 inches deeper and 10 inches wider than the sump. Digging is a tough job, so make sure you’re up to the task before setting out.

Step 4: Install the Sump

You’ll add about 3 inches of gravel to the bottom of the hole, then place the sump in the hole and fill it out the sides with gravel. You’ll leave about 2-3 inches of the top of the sump free of gravel. You’ll add this at the end, after the full installation.

Step 5: Install Sump Pump

Now that the sump is in place, you need to install the pump. First, thread a PVC male adapter into the pump’s discharge pump, then attach a schedule-40 PVC pipe to the male adapter using PVC cement. This is the riser that’ll lead water upwards before you direct it out of the house.

Lower the pump into the sump according to the manufacturer’s instructions. It’s best practice to attach all cabling to the riser PVC using adhesive tape.

Step 6: Run the Pipes

Remember to add a check valve to this PVC pipe and then the second riser after the check valve that will rise upwards until it begins a horizontal run. A second check valve before this horizontal run is also important.

If you need to break through walls, then use a hammer or a drill as you see fit. The important thing is that you seal the hole afterward.

Step 7: Test

After installation, cover the sump and fill up the remaining gravel, then switch it on and test your work.

Most Common Sump Pump Problems

Your sump pump saves you from damp walls and from a basement flooding during emergencies, so it’s in your interest to maintain a fully functional pump.

Following are the most common problems you can experience with your sump pump. By understanding these problems, you’ll be in a better situation to solve or even prevent them.

1. Power Failure

This is the most common problem with sump pumps and it can happen for many reasons. There could be a power outage from a storm or there could be a power surge that damages one or more of the pump’s components.

The solution to this problem is to use a surge protector to prevent damages to your pump and to either have a backup generator or get a pump with a backup battery.

2. Overwhelmed Pump

Different pumps have different capacities and get manufactured with different manufacturer qualities. If your sump pump is doing more work than it got designed for, causing it thereby to run nearly non-stop, then it will sooner or later, develop some problems.

The only solution here is to get a pump with enough horsepower for the job, keeping in mind that more horsepower is better than less. Also, keep an eye on the materials’ quality that got used in making the pump.

3. Clogged Float Switch

Moving parts always pose a problem for machines and the same goes with the float switches that automatically switch the pump on and off. If it gets clogged or hampered in any way, then you’ll need to clean it for it to work again.

4. Clogged or Frozen Discharge Pipes

The discharge pipes that transport the water away from the house could also get clogged up for some reason, including freezing and blocking the proper functioning of the pump system.

You can use grated covering at the pipe’s exit point to prevent animals and debris from blocking it. If the pipe is frozen, then you’ll have to defrost it before regular functioning can resume.

5. Improper Installation

An improperly installed sump pump can also cause a breakdown of the system, so it’s important to follow all the manufacturer’s directions when installing your pump.

If you fail to add a check valve along the discharge pipe, for example, water will keep flowing back into the engine and switching it back on, which will create a continuous On and Off cycle that will eventually wear the pump down earlier than expected.

6. A Defective Pump

Another possibility why the pump isn’t working, and this is when all other tests fail, is that the pump itself is defective and needs repairs or a replacement.

Conclusion

We’ve come to the end of this best sump pump review and you should hopefully have found the perfect pump for your project.

You’ve seen the lightweight and compact ones, as well as the heavy-duty pumps, the submersible ones and the single pedestal sump pump on this list.

​For the best budget pump, the Superior Pump 91250 is a good recommendation, with its low price and 30-GPM capacity.

If you’re interested in raw power, the Wayne CDU980E is the most powerful pump here with its 0.75-HP motor and up to 76-GPM pumping capacity.

Else, for the most reliable system, the Basement Watchdog BW1050 is recommended and it features a dual float switch and a 3-year warranty.
