A sump pump is an essential device that protects homes from flooding by removing excess water from the basement or crawl space. It works by collecting water that accumulates in a pit or sump basin and pumping it outside the house through a discharge pipe. However, sometimes a sump pump may continue to run even when there is no water to pump. This can be an alarming situation for homeowners, and it is crucial to understand the reasons why a sump pump keeps running and how to fix the issue. Sump pumps can fail for a variety of reasons, including power outages, lack of maintenance, old age, or improper installation. In this blog post, we will explore the most common reasons why a sump pump keeps running and what you can do to fix it.
Most common reason sump pump not working
The most common mechanical failure in a sump pump occurs when the switch becomes stuck in the ON or OFF position, causing the pump to run continuously or not at all. Check the power switch and make sure it is not stuck.
The Float Switch is Stuck
Another common reason why a sump pump keeps running is a stuck float switch. The float switch is a mechanism that controls the on/off switch of the sump pump. When the water level in the sump pit rises, the float switch rises with it, triggering the sump pump to turn on. Once the water level drops, the float switch falls back down, turning off the sump pump.
If the float switch becomes stuck in the “on” position, it can cause the sump pump to keep running even when there is no water to pump. This could happen if debris or sediment builds up in the sump pit and prevents the float switch from moving freely. To fix this issue, you can try cleaning the sump pit and removing any debris that may be obstructing the float switch. If the problem persists, you may need to replace the float switch.
The Check Valve is Broken
Another common cause of a continuously running sump pump is a broken check valve. A check valve is a one-way valve that prevents water from flowing back into the sump pit after it has been pumped out. If the check valve is not functioning correctly, water can flow back into the sump pit, causing the sump pump to keep running.
To check if the check valve is working correctly, you can manually lift the float switch and see if water flows back into the sump pit. If it does, you may need to replace the check valve.
The Sump Pump is Oversized
If your sump pump is too large for your sump pit, it may cause the sump pump to keep running. An oversized sump pump may pump out water quickly, causing the float switch to turn on and off rapidly, which can wear out the switch over time.
To fix this issue, you may need to replace the sump pump with one that is the correct size for your sump pit. It is essential to consult a professional to determine the appropriate size of the sump pump for your home.
The Sump Pump is Underpowered
On the other hand, if your sump pump is too small for your sump pit, it may not be able to keep up with the volume of water that accumulates in the pit, causing it to keep running. An underpowered sump pump may also overwork and wear out quickly, leading to more frequent breakdowns.
To fix this issue, you may need to replace the sump pump with one that has the appropriate horsepower for your sump pit. Again, it is essential to consult a professional to ensure that you get the right size of the sump pump for your home.
The Sump Pump is Clogged
A clogged sump pump can also cause it to keep running. Dirt, debris, and sediment can accumulate in the sump pit and clog the sump pump, preventing it from working correctly. A clogged sump pump can also overheat and wear out quickly, leading to more frequent breakdowns. To fix this issue, you should clean the sump pit and get any dirt and debris out.
When should you replace a sump pump?
Replacinga sump pump before it fails is a great way to ensure that your home remains protected, even if you have purchased water backup coverage. But how do you know when you need to replace your sump pump? Here is some important information about knowing when your sump pump might be on its way out.
Loud Noises: If your sump pump starts making loud noises, then chances are it might be getting ready to break down. At the very least, have a professional inspect it. Maybe they will discover a fixable repair. If not, they can tell you if it needs replacing.
Constantly Running: Sump pumps aren’t designed to run constantly. If yours is, it’s an indication that something is wrong. A sump pump that is constantly running is also a strong indicator that your pump is too small for the job and might need to be replaced with a bigger unit.
Sump Pump Age: Also, sump pumps that have been in your home for over 10 years should be replaced. Wear and tear will start to take a toll over time, and the older your pump is, the greater likelihood it’ll start to act up or break down.
