Sump Pump Installation & Repair Columbia, SC
A sump pump is an essential device in homes that are prone to flooding, excess groundwater, or basement moisture. It helps protect your home by preventing water damage, particularly in areas with heavy rainfall or a high water table. Here's when and why you might need a sump pump:
- In Homes with Basements or Crawl Spaces
- In Areas with High Water Tables
- During Heavy Rainfall or Storms.
- In Areas with Poor Drainage
- During Snowmelt (Spring Thaw)
- In Areas with Seasonal Water Flow
- In Homes with Foundation Issues
- In High-Risk Flood Zones
- When You're Installing a Finished Basement
- For Homes with Increased Water Usage or Wet Landscaping
How Does a Sump Pump Work?
A sump pump is typically installed in a sump basinโa hole in the lowest part of the basement or crawl space, often near the foundation. The pump is triggered by rising water levels, activating when the water reaches a certain height. It then pumps the water through a discharge pipe to a location outside your home, typically away from the foundation, to prevent any backflow.
Types of Sump Pumps:
- Pedestal Pumps: These have the motor mounted above the sump basin, making them more accessible for maintenance but potentially louder.
- Submersible Pumps: The motor is submerged inside the sump basin, making these quieter and more compact. Theyโre often better for homes with larger amounts of water.

Most Common Reasons a Sump Pump Stops Working or Needs Repair
A sump pump is an essential piece of equipment for protecting your home from water damage, but like any mechanical device, it can experience issues over time. Here are the most common reasons a sump pump stops working or needs repair:
Power Failure
Sump pumps rely on electricity to function. A power outage during a storm or flooding event can prevent the pump from operating when itโs needed most.
Float Switch Malfunction
The float switch is a crucial part of the sump pump. It activates the pump when the water level rises. If the float switch becomes stuck, damaged, or misaligned, the pump may fail to turn on when itโs needed, or it might run constantly.
Clogged or Blocked Discharge Pipe
The discharge pipe carries water away from the sump pump to a location outside the home. If the pipe becomes clogged with debris, dirt, leaves, or even ice (in colder weather), it can prevent the pump from effectively discharging water.
Burnt-Out Motor
The motor is the heart of the sump pump. Over time, constant use, lack of maintenance, or age can cause the motor to overheat and eventually burn out. If the motor is defective or stops working, the pump won't be able to perform its job.
Incorrect Sump Pump Size
If the sump pump is too small for the job, it may struggle to handle the amount of water itโs supposed to pump. Similarly, a pump thatโs too large may run too frequently, causing wear and tear.
Overwhelmed or Overworked Pump
If your sump pump is frequently running or working under heavy load due to excessive rainfall, high water table, or increased groundwater flow, it can become overworked and may stop functioning properly.
Frozen or Clogged Intake Screen
The intake screen on the sump pump prevents debris from entering the pump. However, it can become clogged with dirt, debris, or sand, preventing the pump from drawing in water properly. In colder climates, the intake or discharge pipe can also freeze, preventing water from flowing.
Improper Installation
If the sump pump was not installed correctly, it may not function as expected. This could include improper pipe connections, an incorrect pump size, or poor placement of the sump pit.
Lack of Regular Maintenance
Without regular inspection and maintenance, a sump pump can become clogged with debris, develop mechanical problems, or suffer from reduced efficiency over time. Ignoring routine checks may allow small issues to become big problems.
Worn-Out Check Valve
The check valve prevents water from flowing back into the sump pit after itโs been pumped out. Over time, this valve can become worn out, damaged, or clogged, leading to water backflow and potentially causing the pump to run continuously.
High Levels of Sediment or Sand in the Water
In areas where the water has high levels of sediment or sand, the particles can clog the pump over time. This can cause the pump to fail, as it will be unable to move water properly.
Most Common Signs To Watch For When A Sump Pump is Failing
A failing sump pump can lead to serious water damage in your home, especially if it happens during a storm or when groundwater levels are high. Here are the most common signs that your sump pump may be failing or on the verge of failure:
Pump Runs Continuously
If your sump pump is constantly running, even when the water level is not high, it could indicate a malfunction in the pumpโs components, like the float switch or check valve. A pump that runs nonstop is working harder than it should, which can lead to premature wear and tear.
Loud or Unusual Noises
A sump pump that is making loud or unusual noises could indicate that something is wrong inside the unit. These noises could come from the motor, impeller, or drainage system.
Water in the Basement or Crawl Space
If you notice standing water in your basement or crawl space, even when the pump is running, the sump pump is likely not performing properly and may be unable to handle the amount of water.
Pump Vibrates or Shakes Excessively
Excessive vibrations or shaking can indicate a misalignment of the pump, a problem with the impeller, or loose parts within the unit. It could also suggest the pump is not seated properly in the pit.
Foul Odors or Mold in the Basement
If your sump pit smells musty or there are signs of mold in the basement, this could indicate water buildup caused by a failing sump pump.
Pump Cycles Too Frequently
If the sump pump is cycling on and off too frequently, it may be struggling to keep up with the water level, or it could be an indication of an overworked pump.
Age of the Sump Pump
If your sump pump is more than 7-10 years old, it may be prone to failure even if there are no obvious signs. Older pumps simply wear out over time, and replacement may be the best option to avoid a breakdown when you need it most.
Frequent Alarm Triggering
Some sump pumps are equipped with an alarm that goes off when the pump is not working properly or when thereโs an issue with the pump system.
What The Installation Process Looks Like
The installation process for a sump pump is a bit involved, but itโs something that can often be done in a single day, depending on your home and the complexity of the installation. Hereโs what the typical process looks like from start to finish:
Evaluate the Site & Choose the Right Sump Pump
The first step is determining where the sump pump will be installed. It needs to be located in the lowest point of the basement or crawl space, where water naturally collects.
A sump pit (also known as a sump basin) needs to be dug if it doesnโt already exist. The pit will house the pump and collect water as it enters your basement.
Itโs essential to select the right size pump based on the water table in your area, the volume of water your home may experience, and the size of the sump pit. A professional can help you choose a pump that is appropriately sized.
Digging the Sump Pit (If Necessary)
If a sump pit is not already in place, the installer will need to dig a hole in the basement floor to create the sump basin. This will be a round or square hole about 18-24 inches in diameter and around 24-30 inches deep.
After digging the hole, the dirt will be removed from the site, and the sump pit will be prepared for the installation of the pump.
Preparing the Sump Pit
The installer will place a sump pit liner in the hole. This is a plastic or fiberglass basin that prevents the sides of the hole from collapsing and helps water flow smoothly into the pump. Itโs often perforated to allow water to easily enter from the surrounding soil.
A layer of gravel will be placed around the pit liner to help improve drainage around the pump. This ensures that water entering the pit doesnโt get blocked by compacted soil.
Installing the Sump Pump
Once the pit is prepared, the sump pump is placed inside the pit. It should be positioned in the center of the pit, sitting on a bed of gravel to allow water to easily flow into the intake.
The pump must be leveled to ensure proper operation. If itโs tilted or not positioned correctly, the pump might not perform efficiently or could even fail prematurely.
The float switch, which controls when the pump activates and shuts off, needs to be installed properly. The switch is typically attached to the side of the pump and should be adjustable to handle varying water levels.
Running the Electrical Wiring
The sump pump needs a power source to run. If your pump has a corded electrical setup, it will need to be plugged into an electrical outlet near the pit. It's important that the outlet is on a dedicated circuit (ideally with a GFCI outlet for safety).
If you are installing a battery backup system, this will need to be wired to the pump as well. The backup system ensures that the pump will continue working during a power outage. This will involve additional wiring and battery placement near the sump pit.
Connecting the Discharge Pipe
A discharge pipe will be connected to the pump to carry the water out of the basement and away from the house. The pipe should ideally lead water to a drainage area far enough from your foundation to prevent the water from seeping back into the basement.
The pipe should be sized appropriately for the pumpโs output and water flow. Typically, 1.5-inch or 2-inch diameter pipes are used.
A check valve will be installed in the discharge pipe to prevent water from flowing back into the sump pit after itโs been pumped out. This is crucial for preventing the pump from cycling unnecessarily.
The discharge pipe should be installed with a downward slope to encourage water flow. If possible, the pipe should exit the home above ground level to prevent any backflow.
Testing the Sump Pump
After the pump is installed, the installer will test it by pouring water into the sump pit to ensure the pump turns on automatically when the water reaches a certain level.
If necessary, the float switch will be adjusted to ensure that the pump activates and deactivates at the correct water levels.
The installer will also test the discharge pipe to ensure the water flows freely out of the house and doesnโt back up into the pit.
Final Touches and Clean-Up
Once everything is connected and tested, the sump pit may be covered with a grate or lid to prevent debris from falling into the pit and to keep animals or children away from the area.
The installer will clean up any debris from the installation process, including dirt and construction materials, and ensure the area is left neat and tidy.
A final inspection is conducted to ensure everything is working as it should and that the system is properly configured.
