💧 How Does a Sump Pump Work?
A sump pump works by collecting water in a sump pit, which is typically located in the basement of a home. The pump then pumps the water out of the sump pit and away from home. This prevents flooding and other damage that can be caused by excess water.
💧 Does My Home Need a Sump Pump?
Whether or not your home needs a sump pump depends on several factors.
The primary factor is the location of your home, as homes in areas prone to flooding may require a sump pump.
Other factors include the age of the home, the type of foundation it has, and whether or not there is already evidence of water damage in the basement.
Additionally, if you live in an area with heavy rainfall or have experienced water problems before, sump pump systems can be beneficial for protecting your home from possible water damage.
💧 Types of Sump Pumps
Primary sump pumps are the main source of water removal and usually run most of the time.
Backup sump pumps serve as a backup in case of a primary pump failure or if the inflow is too much for the primary pump to handle.
Sump pumps come in two varieties: submersible and pedestal. Additionally, backup sump pumps can be further divided into battery-powered and water-powered varieties.
🛠️ Submersible Sump Pumps
A submersible pump is a type of sump pump that is designed to be fully submerged in water. It contains an electric motor, impeller, and volute that work together to draw in water from the sump and pump it out via a discharge pipe.
Submersible pumps are typically used for homes in areas with higher water table levels and can be either primary or backup pumps.
🛠️ Pedestal Sump Pumps
A pedestal pump is a sump pump that sits above the water level in the sump basin.
It consists of an electric motor and impeller mounted on a separate column or pedestal that pumps the water out of the basin.
Pedestal pumps are often used for homes in areas with low water table levels, as there is less risk of damage when they are not left submerged underwater.
They can also be either primary or backup pumps.
🛠️ Battery-Operated Backup
Battery-operated backup sump pumps are designed as supplemental to primary and pedestal models.
Typically, they contain a sealed battery connected to an electric pump and are activated automatically when the power fails or water levels rise above a certain threshold.
They are ideal for areas with frequent power outages or high water table levels, providing extra protection for your home.
🛠️ Water-Powered Backup
Water-powered sump pumps are an alternative to battery-operated or traditional electric models.
They use water pressure from your municipal water service as their power source, eliminating the need for a separate battery or power outlet.
While they are usually more expensive than other types of pumps, they require no additional energy and have the added benefit of being more reliable in areas with frequent power outages.
💧 Types of Sump Pump Switches
Sump pumps can be operated with a switch system to turn on the pump independently.
Several types of switches achieve the same result, but they have different mechanisms of operation.
The manual float switch is activated manually and uses a buoyant arm that moves up and down when liquid levels increase or decrease.
It is the simplest sump pump switch type and is typically used in basic siphoning systems.
The vertical float switch uses an upright arm that moves up and down with the liquid level to activate the motor.
This type of switch works well for automatic applications since it reacts more quickly to rising water levels than a manual option.
A tethered float switch uses the motion of a buoyant object, such as a float, to activate or deactivate electrical circuits.
Diaphragm switches are a type of switch that uses flexible membranes as its sensing element to detect pressure changes in liquids or other substances.
Diaphragm switches are highly reliable, making them the preferred switch type for many applications due to their low likelihood of getting stuck on or off.
Digital float switches are similar to vertical options but use electronic circuitry to operate the sump pump motor instead of a physical arm.
Digital switches usually come pre-programmed with adjustable start/stop settings so they can be easily tailored to suit different applications.
Lastly, toggle switches are designed with large contactors manually switched on or off with the flick of a lever or button.
These switches are primarily used as backup power sources for sump pumps in case of primary power failure.

Inspecting your sump pump regularly is an integral part of its upkeep.
Checking for wear and tear, such as cracks in the ejector or clogs in the pipe, will help you identify any potential problems before they lead to costly repairs.
🧰 Make Sure the Float is Working Properly
Ensuring that the float in your sump pump works correctly is key to keeping it in good condition.
The float should move up and down freely, activating the switch when the water level rises above a certain point and shutting off when it drops below it.
You can check this by manually switching your pump on and off to see if it still functions properly.
🧰 Clean Out Debris and Rocks from the Basin
Over time, debris and rocks can accumulate in your sump pump’s basin.
This can lead to clogs or blockages that could cause the pump to malfunction.
To keep it functioning correctly, cleaning out the basin and removing debris regularly is essential.
Start by turning off the power to the pump before removing any objects from inside the basin.
Once you have cleared away any visible pieces of debris, use a hand vacuum or other tool to suck up any remaining material before replacing the lid and turning the power back on.
🧰 Disconnect and Clear out Any Clogged Discharge Pipe
If your sump pump’s discharge pipe is blocked, it could prevent the water from being properly expelled from the pump and lead to clogs or overflows.
To address this issue, you should disconnect the pipe from the pump and clear out any blockages that may be present.
Start by shutting off the power to the pump and unscrewing the joint that connects the discharge pipe.
Then, inspect it for any obstructions and use a hand vacuum, small brush, or another tool to remove them before reattaching the pipe and turning on the power.
🧰 Test Your Sump Pump Regularly
It’s important to regularly test your sump pump to ensure it is in proper working condition.
Fill the basin with a few inches of water by pouring some from a bucket or hose.
Next, turn on the power and wait to see if the pump kicks in within a few minutes; if not, there may be an issue with the power source or switch, and you should contact a professional for help.
If it does begin running, watch to see that it efficiently pumps out all of the water before turning off on its own.
This process should be repeated every couple of months or when you notice any signs of malfunctioning.
💧 Alternative Options to Sump Pumps
A French drain is a good alternative to a sump pump because it can prevent flooding.
French drains are designed to divert water away from areas with a high risk of flooding.
This allows for more efficient water management, as it takes the pressure off the sump pump and ensures that any excess water is safely diverted away from areas prone to flooding.
Additionally, since French drains are a long-term solution, they can save money in the long run as they don’t require regular maintenance and replacing parts like traditional sump pumps.
Waterproofing Your Basement
Waterproofing can help reduce the risk of flooding in your basement.
By waterproofing your home, you can keep water at bay and away from areas prone to flooding.
Additionally, waterproofing will also help prevent damage caused by water seeping through floors and walls.
This eliminates the need for costly repairs and the regular maintenance required with traditional sump pumps.
Gutter maintenance can reduce the need for a sump pump because it can help keep water away from your basement.
By ensuring your gutters are regularly cleaned and free of debris, you can ensure that they function correctly and that water is directed away from your home.
This will help reduce the chances of flooding as any excess rainwater will be kept away from your basement area, eliminating the need for a sump pump.
Additionally, regular gutter maintenance can also prevent costly repairs related to water damage.
Add Sloping Ground During Construction
Sloping the ground during construction can reduce the need for a sump pump because it helps direct surface water away from your basement area.
By sloping the ground, you are guiding any excess rainwater away from your foundation and towards an area where it can naturally drain away, eliminating the need for a sump pump to move the water manually.
