Dealing with a flooded basement is every homeowner’s nightmare, especially in Nova Scotia, where heavy rainfall and rising sea levels have made flooding a pressing concern.
In fact, the last two years have been Nova Scotia’s worst for catastrophic insured losses on record with a total loss of $581 million in 2022 and $610.9 million in 2023 according to the IBC.
With sump pumps being your home’s main line of defense against flooding, understanding and maintaining your sump pump is crucial to keeping your home and basement dry from rising water levels.
However, like any other mechanical system, sump pumps have a useful life and are prone to wear and tear.
So, let’s enlighten ourselves with eight common sump pump problems and how to fix them to ensure your home stays protected no matter what Mother Nature throws at it.
8 Common Sump Pump Problems & How To Deal With Them
1. Incorrect Sump Pump Sizing
Choosing a sump pump that’s too small or too large can lead to inefficiency. An undersized pump may not handle heavy water flow, while an oversized one can short-cycle, causing wear and tear.
How It Happens:
Homeowners might select a pump without considering the size of their basements or local rainfall patterns.
For example, if your home is located on land with a high water table and you install an undersized pump, it will likely constantly be running, which can strain the motor and lead to eventual failure.
Impact:
An improperly sized pump can lead to increased energy bills and premature pump failure.
Solution:
Assess your basement’s square footage and consult local rainfall data. For instance, areas like Halifax receive significant rainfall, so factor that in. It’s wise to consult with professionals, like the team at Mechanical Flood Protection, to determine the right pump size for your home.
2. Clogged Discharge Lines
Discharge lines can become blocked by debris, ice, or sediment, preventing water from exiting your home.
How It Happens:
Over time, leaves, dirt, and other debris can accumulate in the discharge line. During winter, water inside the piping can also freeze if it is not kept clear.
Impact:
A clogged line forces water back into the sump pit, leading to potential basement flooding.
Solution:
Regularly inspect and clean the discharge line. To combat freezing, ensure the line is pitched correctly.
3. Stuck Float Switch
The float switch is a device that triggers the sump pump to turn off and on. When the water level rises to a certain point in the sump pit it activates the pump. Once the water level drops back to normal the pump switches off.
However, float switches can get stuck or malfunction due to obstructions or mechanical failures.
How It Happens:
A stuck float switch is a very common issue. Debris can jam the switch, preventing it from moving up or down. The switch can also get stuck against the sides of the sump pit.
Impact:
A faulty or stuck switch means the pump won’t activate when needed, which can lead to flooding. A stuck float switch can also result in the sump pump constantly running resulting in increased energy bills and greater wear and tear.
Solution:
Regularly clean the sump pit to remove debris. Ensure the float moves freely. If problems persist, replace the float switch if necessary.
4. Frequent or Continuous Running
If your sump pump is running non-stop it can wear out quickly and spike your energy bills.
How It Happens:
This can result from a stuck float switch, a pump that’s too small, or a high water table in your area.
Impact:
Continuous operation leads to increased wear and potential pump failure.
Solution:
Check the float switch for obstructions. If your pump is undersized, consider upgrading. Also, if you live in an area with a high water table, like some parts of Dartmouth, consider installing a secondary or backup pump for added flood protection.
5. Overwhelmed Sump Pump
During heavy storms, your sump pump might struggle to keep up with the water influx and as a result, may run constantly for hours or even days.
How It Happens:
Intense rainfall or rapid snowmelt can quickly cause water levels to rise and overwhelm your pump’s capacity.
Impact:
An overwhelmed pump can lead to potential failure resulting in basement flooding.
Solution:
Consider installing a backup pump or battery-powered system. Regular maintenance can also help ensure your pump operates at peak efficiency during critical times.
6. Power Failures
Power outages are common, especially during heavy storms in both urban and rural areas of Nova Scotia. No power means your electric sump pump is no longer operational which can leave your basement vulnerable.
How It Happens:
Severe storms can cause trees to fall and knock out power lines, resulting in mass power outages which can last for days.
Impact:
Without power, the pump can’t operate, leading to potential flooding, especially during heavy rainfall.
Solution:
Invest in a battery backup or water-powered backup system to keep your pump running during outages.
7. Frozen or Blocked Pipes
In Nova Scotia’s cold winters, discharge pipes can freeze, blocking water flow.
How It Happens:
Standing water in the discharge line can freeze during low temperatures.
Impact:
A frozen pipe prevents water from exiting, causing backups and potential flooding.
Solution:
Ensure the discharge line has a proper slope to prevent standing water. Also, consider insulating the pipe or installing a heat cable to prevent freezing. Regularly check for blockages, especially before winter sets in.
8. Loud Noises and Vibrations
While sump pumps do make a low humming sound while operational, unusual sounds from your sump pump such as grinding, clanging, and banging can indicate mechanical issues.
How It Happens:
Worn bearings, debris in the impeller, or improper installation can cause loud and unusual noises.
Impact:
Ignoring these sounds can lead to pump failure and expensive repair or replacement costs.
Solution:
Inspect the pump for debris and clean it. Ensure it’s securely mounted. If noises persist, consult professionals like Mechanical Flood Protection to assess and repair the issue.
