Uncover the secret: why does your sump pump keep running? (hint: it’s not the rain)
What To Know
- Sump pumps are usually activated by a float switch, which turns on the pump when the water level in the basin reaches a certain height.
- The float switch is the device that turns on the sump pump when the water level in the basin reaches a certain height.
- A high water table is a condition in which the water level in the ground is close to the surface.
A sump pump is an essential part of any home that is prone to flooding. It works by pumping water out of a sump basin, which is a pit that collects water from the ground around your home. Sump pumps are usually activated by a float switch, which turns on the pump when the water level in the basin reaches a certain height.
However, sometimes sump pumps can start running even when it’s not raining. This can be a frustrating and confusing problem, especially if you’re not sure why it’s happening. In this blog post, we’ll explore the most common reasons why your sump pump might be running when it’s not raining and provide solutions to fix the issue.
Reasons Why Your Sump Pump Runs When It’s Not Raining
There are several reasons why your sump pump might be running even when it’s not raining. Some of the most common causes include:
1. Groundwater Infiltration
Groundwater infiltration occurs when water from the ground seeps into your sump basin. This can happen even if there is no rain, especially if the ground around your home is saturated with water. To prevent groundwater infiltration, make sure that the ground around your home is properly graded and that there are no cracks or holes in your foundation.
2. Clogged Discharge Line
The discharge line is the pipe that carries water away from your sump pump. If the discharge line is clogged, water will back up into the sump basin and cause the pump to run continuously. To prevent this, make sure that the discharge line is clear of debris and that it is not frozen.
3. Faulty Float Switch
The float switch is the device that turns on the sump pump when the water level in the basin reaches a certain height. If the float switch is faulty, it may turn on the pump even when the water level is low. To test the float switch, remove it from the sump basin and manually activate it. If the pump turns on, the float switch is faulty and needs to be replaced.
4. Broken Check Valve
The check valve is a device that prevents water from flowing back into the sump basin after the pump has turned off. If the check valve is broken, water can leak back into the basin and cause the pump to run continuously. To test the check valve, pour water into the discharge line. If water flows back into the basin, the check valve is broken and needs to be replaced.
5. Power Outages
If you have a power outage, your sump pump will not be able to run. This can cause water to build up in the sump basin and eventually overflow. To prevent this, make sure that you have a backup power source for your sump pump, such as a battery or a generator.
6. High Water Table
A high water table is a condition in which the water level in the ground is close to the surface. This can cause water to seep into your sump basin even if there is no rain. To prevent this, make sure that the ground around your home is properly graded and that there are no cracks or holes in your foundation.
7. Other Causes
In some cases, your sump pump may be running when it’s not raining due to other factors, such as:
- A leak in your plumbing system
- A crack in your foundation
- A malfunctioning sump pump
How to Fix a Sump Pump That Runs When It’s Not Raining
If your sump pump is running when it’s not raining, there are a few things you can do to fix the problem.
1. Check the groundwater level. If the groundwater level is high, you may need to install a sump pump with a higher capacity.
2. Clear the discharge line. Remove any debris or ice that may be clogging the discharge line.
3. Test the float switch. Remove the float switch from the sump basin and manually activate it. If the pump turns on, the float switch is faulty and needs to be replaced.
4. Replace the check valve. If the check valve is broken, water can leak back into the sump basin and cause the pump to run continuously.
5. Install a backup power source. If you have a power outage, your sump pump will not be able to run. This can cause water to build up in the sump basin and eventually overflow. To prevent this, make sure that you have a backup power source for your sump pump, such as a battery or a generator.
