Guide to Sump Pumps: What They Are and How They Work

As you walk into your basement, you notice a strange device humming away in the corner – a sump pump. But what is it, and how does it work its magic to keep your home dry and flood-free?

You’re not alone in wondering – many homeowners are unsure about the inner workings of this essential device. The truth is, a sump pump is more than just a noisy machine; it’s a guardian against water damage and costly repairs. But to truly appreciate its importance, you need to understand how it functions and what makes it tick.

Key Takeaways

• A sump pump is a device that removes water that accumulates in a water-collecting sump basin, commonly found in basements below the water table.

• A sump pump system kicks into action when water starts accumulating in the sump chamber, triggering a float switch that activates the pump.

• There are two main types of sump pumps: submersible pumps, which are submerged in the sump pit, and pedestal sump pumps, which sit above the pit.

• A sump pump is designed to redirect water away from the home to a convenient drain off point, preventing water damage and flooding.

• The water table, soil type, and drainage system are essential factors to consider when selecting a sump pump.

What is a sump pump?

In your basement, a sump pump is basically a lifesaver, a device that removes water that accumulates in a water-collecting sump basin, commonly found in basements below the water table.

This device is especially vital in areas where the water table is above the foundation level, making it prone to flooding.

A sump pump, specifically a submersible sump pump, is designed to redirect water away from your home to a convenient drain off point.

When the water level inside the chamber reaches a certain level, the pump automatically kicks in, draining the water away from your basement.

This safeguard prevents water damage and flooding, giving you peace of mind and protecting your belongings.

How does a sump pump work?

Your sump pump system kicks into action when water starts accumulating in the sump chamber, triggering a float switch that activates the pump. As the water level rises, the float switch signals the primary sump pump to start pumping water out of the sump pit and away from your home.

There are two main types of sump pumps: submersible pumps, which are submerged in the sump pit, and pedestal sump pumps, which sit above the pit. Both types are designed to efficiently remove water and prevent flooding.

The sump pit collects water that drains from the surrounding area.

The float switch triggers the pump when the water level reaches a certain height.

The pump activates and starts pumping water out of the pit.

The water is redirected away from the home through internal pipes, preventing flooding and damage.

Do you need a sump pump?

Determine if you live in a high-risk flood area or have a history of water damage in your home to decide if investing in a sump pump is necessary for your peace of mind and property protection.

If you’re unsure, consider the consequences of a flooded basement: water damage, ruined possessions, and a hefty repair bill.

A sump pump can be a lifesaver in such situations, providing a reliable safeguard against flooding and damage.

You may need a sump pump if you live in an area prone to heavy rainfall, have a history of water accumulation in your basement, or experience frequent power outages that can disrupt your home’s drainage system.

Additionally, if you’ve noticed water seepage or dampness in your basement, a sump pump can help alleviate these issues.

Where does a sump pump discharge?

After collecting and pumping out water from your basement, a sump pump discharges it to a suitable location away from your home’s foundation. This ensures that the water doesn’t flow back into your basement, causing further damage. The discharge location is typically a storm drain, sewer, or a natural watercourse, such as a creek or pond.

When it comes to discharging water, it’s vital to take into account the following:

• Drainage regulations: Check with your local authorities to confirm you comply with drainage regulations and avoid fines.
• Water flow: Verify the discharge location can handle the water flow from your sump pump to prevent backups and flooding.
• Distance from foundation: Discharge the water at least 10-15 feet away from your home’s foundation to prevent water from seeping back into your basement.
• Environmental impact: Be mindful of the environmental impact of discharging water into natural watercourses, and contemplate using a sedimentation tank or oil interceptor if necessary.

What are the types of sump pumps

There are two main types of sump pumps submersible and pedestal pumps, which differ in design and functionality, as well as manual or automatic pumps that vary in operation.

Additionally, you’ll need to ponder factors like power, head pressure, and backup and alarm systems to guarantee you choose the right pump for your unique situation.

Submersible and Pedestal

When it comes to choosing the right sump pump for your home, you’ll likely encounter two primary types: submersible and pedestal pumps, each with its unique characteristics and benefits. Understanding the differences between these two types is crucial to making an informed decision.

Submersible pumps are designed to be submerged in water and are typically more powerful and efficient. They work by pumping water out of the sump basin and into the discharge pipe.

On the other hand, pedestal pumps sit above the sump basin and use a pipe to draw water from the basin.

Submersible pumps are more powerful and efficient, but may be noisier and require more maintenance.

Pedestal pumps are generally quieter and easier to maintain, but may be less powerful and more prone to clogging.

Sump pump work is affected by the type of pump you choose, with submersible pumps handling heavier water flows and pedestal pumps better suited for smaller amounts of water.

Pedestal sump and pedestal pump combinations are often used in smaller spaces or where a quieter operation is desired.

Manual or Automatic Pump

You have two primary options when it comes to choosing a sump pump: manual or automatic, each with its unique benefits and drawbacks that can substantially impact your home’s protection against flooding.

A manual pump requires you to physically switch it on and off, which requires you to be there and will lead to delays in responding to flooding.

An automatic pump is equipped with a sensor (float switch) that detects water levels and automatically activates the pump when needed.

When selecting between manual and automatic pumps, consider your specific needs and priorities.

If you’re looking for a more affordable option and don’t mind taking a more hands-on approach, a manual pump might be the way to go.

However, if you prioritise convenience and want a more reliable solution, an automatic pump could be the better choice.

Either way, it’s essential to choose a pump that suits your specific needs and provides the necessary protection for your home.

The amount of power

Selecting the right power for your sump pump is essential, since it directly affects the pump’s ability to handle water flow and how far it can pump it to prevent flooding.

When choosing a primary pump, you’ll encounter two main types: submersible pumps and pedestal pumps.

Submersible pumps: More visually appealing, but can be more expensive and tricky to repair.

Pedestal pumps: Often more economical, but may not last as long as submersible pumps. Can be noisy and prone to overheating.

Power balance: Verify that the pump’s power rating matches your basement’s flooding risk and water table level and the distance you have to to handle water flow effectively.

Quality matters: A good quality sump pump can run for an average of 20-24 hours straight, while a low-quality pump may only last 6-18 hours in a 24 hour period, depending on the power and usage.

Head Pressure

Your sump pump‘s head pressure is just as important as its power, as it determines how high the pump can push water up and away from your basement.

Head pressure refers to the maximum height that your pump can push water, typically ranging from 5 to 20 metres.

The type of sump pump and its power rating substantially affect the head pressure. For instance, a 0.25Kw sump pump typically has a head pressure of around 7.5 metres, while a 1.1Kw pump can handle up to 18 metres.

Additionally, the head pressure depends on the diameter and length of the discharge pipe, as well as the number of elbows and fittings, which can reduce the pump’s overall performance.

When selecting a sump pump, it’s essential to take into account the specific head pressure requirements of your basement, bearing in mind factors such as the water table, soil type, and drainage system.

Back up and Alarm Systems

In addition to a reliable sump pump, a backup system and alarm can provide an added layer of protection against basement flooding and water damage. You never know when a power outage might strike, leaving your primary pump useless. That’s where a backup sump pump comes in.

A battery backup system guarantees your pump keeps running during power outages, giving you peace of mind.

A high-level water alarm can alert you to rising water levels or pump failure, allowing you to take action before it’s too late.

Some backup pumps can run for up to 24 hours on a single battery charge, providing extended protection during prolonged power outages.

A well-maintained alarm system can prevent basement flooding and damage by alerting you to potential issues before they become major problems.

What is the best sump pump for my home?

When determining the best sump pump for your home, you’ll want to evaluate a combination of key factors, including power, head pressure, and type of pump, to guarantee you get a system that effectively protects your basement from water damage.

A primary sump pump with a power between 0.25kW and 0.25kW is a good starting point.
