When Should a Sump Pump Run? What Every Homeowner Should Know
A sump pump is supposed to run when heavy rain causes groundwater around your foundation to rise. In fact, hearing it turn on is often a good sign that it’s doing its job and keeping water out of your basement.
That said, there are times when a sump pump running too often, running nonstop, or not running at all can be a sign something needs attention.
In this guide, we’ll walk through what’s normal, what isn’t, and when it makes sense to have your system checked. If you’re ever unsure whether your sump pump is working the way it should, Summit Waterproofing Solutions provides sump pump inspections, maintenance, repairs, and replacements throughout Northern Virginia.
How Often Should a Sump Pump Run?
Some homes only need the pump during the biggest storms. Others have a naturally high water table or more groundwater around the foundation, so it’s completely normal for the pump to cycle on and off every time it rains. After a heavy storm, it may even continue running periodically for a day or two while the soil around the home slowly drains.
What matters isn’t how many times the pump turns on. What matters is whether it’s keeping up with the water coming into the sump pit. If the pump turns on, pumps the water out, and shuts back off, that’s usually a sign the system is working the way it should.
It’s also normal to notice your sump pump running more often during certain times of the year. Long periods of rain, summer thunderstorms, snowmelt, and naturally wet seasons can all cause groundwater levels to rise and make the pump work harder.
When Should I Be Concerned About My Sump Pump?
If your sump pump suddenly starts running much more than it used to, or it never seems to shut off even after the ground has had time to dry out, that’s when it’s worth taking a closer look. Those can be signs the pump needs attention or that there’s a larger drainage issue that should be inspected.
It’s a good idea to have your sump pump inspected if you notice any of the following:
- It runs continuously for days after the weather has cleared. While it’s normal for a sump pump to continue cycling after a storm, it shouldn’t run nonstop indefinitely.
- It runs even when it hasn’t rained. This could point to a stuck float switch, a plumbing issue, or unusually high groundwater levels.
- It never turns on during heavy rain. If water is collecting in the sump pit and the pump doesn’t activate, the system may have failed.
- The sump pit is overflowing or your basement is taking on water. This usually means the pump can’t keep up or isn’t working properly.
- It suddenly starts running much more than it used to. A noticeable change in how often the pump runs could indicate a developing problem with the pump or your drainage system.
If something about your sump pump seems different than normal, it’s worth having it checked before the next big storm.
Signs Your Sump Pump May Need Repair
- The float switch isn’t working properly. The float is what tells the pump when to turn on. If it gets stuck or stops working, the pump may not start when the sump pit fills with water, increasing the risk of basement flooding.
- The discharge line is clogged. The discharge line carries water away from your home. If it’s blocked by debris or another obstruction, water can’t drain properly and may flow back toward the foundation.
- The pump is making unusual noises. Grinding, rattling, or loud humming often means something inside the pump is wearing out or not working the way it should.
- The pump runs, but the water level never goes down. If the sump pit stays full while the pump is running, the pump may be losing power, clogged, or simply unable to keep up with the amount of groundwater entering the system.
- The check valve has failed. The check valve keeps water from flowing backward into the sump pit after it’s been pumped out. When it fails, the pump has to work harder because it’s moving the same water over and over again.
- The sump pit is full of mud or debris. Dirt and sediment can clog the pump or interfere with moving parts, making it less reliable when you need it most.
- The pump is getting older. Most sump pumps last around 7 to 10 years. If yours is approaching that age and hasn’t been inspected recently, it’s worth having it checked before the next major storm.
How Often Should a Sump Pump Be Maintained?
Most manufacturers and waterproofing professionals recommend having your sump pump serviced at least once a year, ideally before the rainy season or periods of heavy storms. Regular maintenance helps catch small problems before they become expensive ones. A worn float switch, partially clogged discharge line, or aging pump may not cause noticeable issues during light rain, but they can quickly become a problem when your sump pump is working its hardest during a major storm.
If you can’t remember the last time your sump pump was inspected, or it’s been several years since it’s been serviced, it’s a good idea to have it checked.
Should My Sump Pump Have a Battery Backup?
Yes! A battery backup is one of the best ways to protect your basement from flooding during power outages. If the electricity goes out, a standard sump pump stops working even if water is still flowing into the sump pit.
A battery backup automatically takes over when the power goes out, allowing your sump pump to keep removing water until electricity is restored. That extra layer of protection can make a big difference during a long storm.
A battery backup is especially worth considering if:
- Your basement has flooded before.
- You have a finished basement or valuable belongings stored downstairs.
- Your sump pump runs frequently during heavy rain.
- Your neighborhood is prone to power outages during storms.
