8 Ordinary Sump Pump Problems and How To Fix
To truly clean the sump pump, you’ll need to remove the pump from the basin. You’ll first need to disconnect the discharge pipe from the pump. If the pipe seems stuck on the pump, try using WD-40 to loosen the connection and avoid damaging the pump or the pipe. Keep in mind that resistance can indicate that mold is building up around the connection site. If this is the case, you’ll want to use disinfecting vinegar or bleach to kill the mold—but never both ingredients together.

How often should a sump pump run? What do you need to do to maintain a sump pump? If you’ve been asking these questions, you’re in the right place.
A sump pump works to keep a basement dry by moving water away from the house. It consists of a sump or basin in the basement floor that holds a large pump. Also inside the sump are special valves that can sense the water level and pressure. If the water level rises too much within the sump, the pump will move water away from the house through the discharge line.
Clearly, a sump pump has a very important job. If it stops functioning correctly, you could end up with a flooded basement. The following sump pump inspection and maintenance steps are important and should be performed at least once a year. If you live in an area with a lot of rain or snow, your sump pump will work even harder, and might require quarterly maintenance.
1. Clear the sump basin of debris.
Before you get into following the steps necessary for how to clean a sump pump, you should start by unplugging the unit from the power supply. Never clean a sump pump while it is still plugged in, since this can be very dangerous.
Then, remove any loose or large debris from the basin. This step is important to make it easier to remove the pump itself for a more thorough cleaning.
2. Remove the pump and thoroughly check for corrosion or other damage.
To truly clean the sump pump, you’ll need to remove the pump from the basin. You’ll first need to disconnect the discharge pipe from the pump. If the pipe seems stuck on the pump, try using WD-40 to loosen the connection and avoid damaging the pump or the pipe. Keep in mind that resistance can indicate that mold is building up around the connection site. If this is the case, you’ll want to use disinfecting vinegar or bleach to kill the mold—but never both ingredients together.
Once the pump has been disconnected from the discharge pipe, take it out of the basin and place it in a large trash bag. Bring the pump and bag outside where you can work without worrying about making a mess in the house. Of course, if you have an external sump pump, you can skip this move, since you’ll already be outside.
Use a damp cloth or a sponge to wipe the sump pump and remove any grime. If there is a lot of buildup and gunk that needs to be removed, you can also spray the pump with a garden hose or use a diluted vinegar solution. While cleaning the pump, examine it closely for any signs of corrosion or damage. If you notice anything that looks off, you’ll want to contact a qualified professional to fix it before too much damage to the pump occurs.
3. Clean the pump inlet screen.
The sump pump inlet screen is located along the base of the pump. This screen acts as a filter to keep debris from entering the pump itself and causing damage. To clean the sump pump screen, use a scrub brush to remove any buildup or debris that might be caught in the filter.
4. If recommended by the manufacturer, lubricate pump bearings.
Next, read through your owner’s manual to see if the manufacturer recommends lubricating the pump bearings.
Some sump pumps are designed with sealed bearings. These models will not need to be lubricated, while pumps with unsealed bearings will require lubrication.
5. Inspect the outside discharge pipe and surrounding area.
The sump pump’s drainage system should also be inspected to make sure water is carried far away from your home to prevent threats to your home’s foundation. Check the discharge pipe for the sump pump to ensure that it is in place and directing water at least 20 feet away from your home. You will also want to confirm that the pipe is unclogged and clean to ensure water can flow through it freely.
6. Test the pump to ensure it works properly.
Finally, bring the pump back inside, place it in the basin, and reconnect the discharge pipe. Then, pour a few buckets (approximately five gallons) into the basin.
Plug the sump pump back into the power source. If the pump is working properly, it should kick on and start pumping the water out of the basin and into the discharge pipe. Watch the float switch carefully during this time to confirm that it starts and stops the pump at the appropriate times based on the amount of water present in the basin.
8 Ordinary Sump Pump Problems and How To Fix
A sump pump is your home’s defense against flooding. However, when it begins failing, it could worsen the outstanding problem or even trigger the inundation of your basement or crawlspace. If your sump pump is constantly running or inoperable, we have created a list of ordinary types of sump pump problems and troubleshooting methods.

No Water in Sump Pit
If there is no water in your sump pump pit and your system doesn’t seem to be malfunctioning, it may not be connected to the drainage system in your home correctly. You should have a drain tile inside or outside your home that collects incoming groundwater and diverts it to your sump pump. From there, your pump pushes it into the sump basin to drain away.
Clogged Switches and Sump Pumps
There are a lot of problems that may cause the switch that is integrated with your sump pump to fail. The source of the broken switch may be dirt or debris in the sump pit. In addition, the float switch that is engineered to maintain the sump pump may be stuck. We can take a look to determine whether you need some basic maintenance, repair, or a replacement with an airtight lid and even a pedestal.
Loss of Power
Your sump pump can’t work if a storm knocks down your power, your circuit breaker trips, or the pump gets unplugged. Snell can help you put in a high-performing, battery-powered pump and verify that it has a battery backup and alarm system so you know when your home’s vulnerable.
Ice in Discharge Lines
A sump pump rids itself of water through discharge lines. However, it is not abnormal for the drainage pipes to become frozen during the winter season. To eliminate this problem, a licensed technician can install a line attachment that prevents water from flowing out to the icy lines. In addition, a certified plumber in Ashburn, VA is able to reroute your lines to keep them clear, covered, and far from your foundation.
Sump Pump is An Incorrect Size
Believe it or not, there is a right-sized sump pump for your home. If your sump pump is constantly running, this is a sign that your pump is too big or small. Since an undersized sump pump will struggle to remove water from your basement, it will reach the end of its life cycle at a faster rate. For the most part, it’s safest to replace an old sump pump with another of the same size. If your home sits in a swampy/marshy area or contains a high vertical lift or long-running pipes, a licensed plumber can consult you on how a larger-sized pump could help if needed.
Incorrect Installation
We previously mentioned that an improperly-installed sump pump can keep it from pushing water out of your home. A poor installation job would mean that your pump wasn’t stabilized, set onto a clean surface, or given a check valve to prevent backflow and a discharge line relief hole to release air pressure.
Not Performing Maintenance
Fortunately for homeowners like yourself, there’s not a lot you have to do to keep your sump pump in tip-top shape! During dry spells, pour some water into the crock occasionally to keep it running and lubricated. Call a licensed technician prior to the spring season to ensure your sump pump is prepared for thunderstorms and rain showers. A certified technician will clean or replace the parts in your sump pump to prevent problems during the spring and summer seasons.
Defective Model and Product
Every once in a while, sump pump components are manufactured with some sort of error or flaw. To prepare for this rare occurrence, we test your sump pump right after installation. You should register the warranty with the manufacturer and keep your receipt anyway in case you have to file a claim later on.
4 Common Sump Pump Noises
Besides the alarm, there are other sounds your sump pump could make to indicate that there’s a problem.
Grinding Noises
If there’s a grinding sound coming from your sump pump, the impeller could be stuck or in need of replacement. This part keeps water from coming up your pump, so a licensed technician will ensure it’s working right correctly when you schedule an appointment.
Clanging Noises
Clanging noises can come from pipe vibrations while the sump pump is operating. The quickest way to fix this problem is to insulate the pipes that are connected to the pump. Otherwise, you may just need a knowledgeable technician to retrofit your discharge pipe so it’s in a more functional (and quieter) position.
Humming Noises
A sump pump usually runs with a humming sound. If it’s noticeably noisier than usual: try cleaning out the vent hole, resetting the check valve to discharge, and carefully warming up frozen pipes. If none of those options work, schedule an appointment with us to clean or replace your impeller and filter.
Banging Noises
A certified contractor can securely fasten down your discharge pipes to keep them from banging around with wiring and brackets. In addition, a technician will inspect the internal wiring and parts in your sump pump to ensure you do not encounter problems throughout the year.
