A sump pump is supposed to turn on when water reaches a certain level and shut back off once the pit has been cleared. So if your sump pump is running constantly, running long after the rain has stopped, or simply will not shut off, something deserves a closer look.
Not every San Antonio home relies on a sump pump, but for homes that do, the system may be an important line of defense against water collecting in a low area, crawl space, or other part of the property. When the pump will not stop running, the problem could be as simple as a stuck switch or a sign that water is entering faster than the system can handle it.
If your sump pump will not stop running, Yell for George. Our licensed plumbers can evaluate the system, find the source of the problem, and explain your repair options.
Why Does a Sump Pump Keep Running?
A sump pump that runs frequently during heavy rain is not automatically broken. The concern is when the pump continues operating even after the water level has dropped or seems unable to keep up.
Some of the most common causes include:
- A stuck float switch: The float tells the pump when the water level is high enough to turn on. If it becomes stuck in the raised position, the pump may continue running even after the pit is empty.
- A problem with the check valve: A check valve helps keep pumped water from flowing backward into the sump pit. If it is not working correctly, the same water may keep returning and trigger another cycle.
- A clogged or restricted discharge line: If water cannot move freely away from the home, the pump may have to run much longer than normal.
- Too much incoming water: During periods of heavy rain, drainage issues around the property can send more water toward the sump pit than the system normally handles.
- An undersized or aging pump: A pump that is too small for the amount of water entering the pit may run almost continuously. Older equipment may also lose performance over time.
What Should You Check First?
You do not need to take the pump apart to gather useful information. Start by listening to how it is operating and checking the sump pit if you can do so safely.
Is there still a lot of water entering the pit? Is the water level dropping? Does the pump continue running even when the pit is nearly empty? Those details can help distinguish between a drainage issue and a mechanical problem with the pump itself.
You can also look for an obviously stuck float or a discharge pipe that appears blocked or damaged. Avoid reaching into the pit, removing electrical components, or attempting repairs around standing water.
Can a Sump Pump Burn Out From Running Constantly?
Yes. Sump pumps are designed to work when water needs to be removed, but continuous operation puts additional wear on the motor. If the pump is running around the clock because of a stuck switch, restricted discharge line, or another problem, eventually it may overheat or fail.
That becomes especially concerning if the pump is the main thing preventing water from reaching part of your home. Fixing the reason for constant operation now can help prevent the pump from failing when you need it most.
When Should You Call a Plumber?
If your sump pump will not stop running, cannot keep the water level down, repeatedly turns on and off, or has suddenly started behaving differently, it is a good idea to have it checked.
