It’s that time of year when heavy rainfall and melting snow can make their way into your basement, effectively turning your ground floor into a swimming pool. Having excessive amounts of water in your basement is extremely harmful and dangerous, and with every passing minute, the danger increases.

A flooded basement can cause extreme damage to your foundation and the overall structural integrity of your home. It can cause mold and mildew to occur and poses various risks to your electrical and gas systems as well.

To prevent such issues from occurring, what you need is a pump for basement flooding. Although it doesn’t have to be anything fancy, the best pump for basement flooding has to function properly. This means it should be durable, turn on when required and have enough power to quickly move large quantities of water out of your basement before anything serious happens.

That said, finding the best pumps for a flooded basement can be very difficult. Fortunately, that’s what we’re here to help with today. We’ll start by highlighting several considerations when buying a pump for floods, followed by a comprehensive review of the best pumps for flooded basements that money can buy.

Key Takeaways

  • The major considerations when choosing the best pump for basement flooding include the types of switches available, housing, horsepower, and water capacity.
  •  Always use the right tool for the right task, this is why sump pumps have different features and capabilities.

What to Consider When Buying a Pump for Floods

Before we take a look at the very best pumps for flooded basements, here are some key factors to think about. After all, it’s difficult to make a choice if you don’t know what you’re looking for.

Types of Switches

The most important consideration when choosing the best pump for floods is the switch type. A switch on a utility or sump pump is the mechanism or internal sensor that causes the pump to turn on when water is present. Let’s take a quick look at each of the four main types of switches.

  • Tethered Float: With a tethered float or tethered switch, these can be piggybacked or internally wired. These are common as they are very simple. The switch consists of a round float with a mercury or a steel ball inside.The float is attached to the basin lid or pump with a cord. As water in the basement rises, the float extends the cord, and it starts to pivot. The floating switch pivots straight upwards, which forces the steel ball or mercury to sink to the bottom, powering the switch. When the water level falls, the cord extends down once again, thus causing the pump to turn off.
  • Vertical Float: One of the best switches for sump pumps is the vertical switch. These use a piggyback plug, are adjustable and very easy to install. They’re ideal for common purposes such as basement flooding. The switch comprises a float, a rod, and a smaller switch inside a housing that attaches to a discharge pipe. As the water level rises in the sump basin, the float also rises, and the switch will activate once the float reaches a certain height, therefore turning the pump on.
  • Electronic: A newer kind of switch is the electronic float or electronic switch. These have almost no moving parts, making them fairly durable and low maintenance. Most of these models have a simple probe attached at the level that you want the pump to activate. Other models may have one or two floats as well as sensors that determine the height of the float, and then turn on the pump accordingly. Generally speaking, these are some of the most durable switches, but also the most expensive.
  • Diaphragm: Although not quite as common for home use, another type is the diaphragm switch. Diaphragm switches activate using pressure. As the water level rises in the sump basin, it compresses a small bladder inside of the switch that activates the pump. When the water level decreases, the bladder is depressurized, which causes it to expand, and ultimately results in the pump turning off.

Horsepower

The next factor to keep in mind when choosing the best sump pump for a flooded basement is power. This is generally measured in horsepower (hp). The most common horsepower levels for these pumps are 1/4 hp, 1/3 hp, 1/2 hp, 3/4 hp, and in rare cases, 1 hp.

Unless you’re expecting a huge flood, 1/3 hp should be enough in most cases. A pump’s horsepower determines how much water it can move. In general, a sump pump with around 1/2 hp should be able to pump around 3,000 gallons of water per hour.

Housing

Another factor to consider is the material the pump is made of, i.e., the housing. The two most common types are cast iron and plastic. Plastic pumps are generally the least expensive, which makes them ideal for people operating on a budget.

It really comes down to is cost versus quality – cast iron models are much more durable, impact resistant, and generally have higher quality interior components as well. A cast iron sump pump will likely outlive several plastic models.

Some may also be made out of stainless steel, which is lightweight yet also very durable. These sit neatly between plastic and cast iron in terms of longevity, durability, weight, and cost. The housing goes a long way in determining the best utility pump for basement flooding.

Cord Length

You may also want to consider how long the power cord is before making a purchase. You don’t want to buy a unit with a 10’ power cord only to realize that the closest outlet is 15’ away. Although it might not be the number one factor to consider when choosing the best water pump for basement flooding, it does make a difference.

Water Capacity

Also consider how many gallons of water per hour the pump can move. Some may only be able to move a few hundred gallons whereas others will move thousands. What you get depends on your own specific circumstances.

You might also want to think about the minimum water depth for the pump to function. Some pumps stop working when there are several inches of water left on the ground, while others get extremely close to the ground, to within fractions of an inch. The best water pump for basement flooding should be able to move great quantities of water in short periods of time.

Best Pumps for Flooded Basements

Now that we know what to look for in sump pumps for flooded basements, let’s take a closer look at some of the best models out there right now. 

Wayne WaterBUG

The Wayne WaterBug Submersible Water Removal and Transfer Pump is a great model for small or medium sized applications. It might just be the best pump for basement flooding. It features a 1/6 horsepower motor that can move up to 1350 gallons of water per hour. This should be enough for small yards, basements, and even pools.

What’s more, it can remove water down to a depth of 1/16th of an inch, therefore getting very close to the floor, not to mention that it also has various water removal options. It has a top discharge which is ideal for smaller spaces, as well as a side discharge which is ideal for large and flat surfaces.

It also has a number of features that make it one of the best in its class, such as corrosion-resistant plastic discharge outlets. On that note, it should be able to fit standard garden hoses. To keep the interior safe from damage, it has a suction strainer debris filter to prevent small items from clogging up the works.

Although it may be made of plastic, the housing is fairly tough, more than enough to withstand some impact. Thermoplastic is not just any old regular plastic! In spite of its tough exterior, it comes in at a relatively low weight and small size, therefore making it portable and easy to maneuver.

  • Power: 1/6 HP
  • Water Capacity: 1350 gallons per hour
