Remove the Sump Pump

Once it’s unplugged and detached, lift the pump from the sump basin. To clean the sump pump, use a rag to wipe it down. If it’s really dirty, take it outside and hose it off with water. It’s a good idea to place the sump pump into a large bucket or inside a trash bag to collect any water drips and prevent a mess on the floor.
Clear Any Clogs From the Discharge Lines
Use a flashlight to look inside the entry and exit of the drain discharge lines. In many instances, the reason why a sump pump is not working or draining is because of large pebbles and other debris getting lodged in the lines. This prevents water from entering and exiting the discharge lines from the sump pit. As part of your regular sump pump maintenance, it’s a good idea to check the entry and exit of your discharge lines to ensure they’re clear.
Remove Sediment From Inside the Discharge Lines
When your sump pump brings in water from outside, it can also bring in dirt, sand, and other sediment, which builds up over time. Sometimes, the sediment will build up near the front of the discharge lines, which you can easily scoop out by hand or scrape out with a screwdriver.
But you might discover the blockage is further in the lines, making it not-so-easy to reach. In this case, you can use a wet/dry shop vac or a drain snake to help clear the clog.
Test the Lines
Once the discharge lines are free of any clogs and blockage, test them to make sure they drain easily. Fill a large bucket with water—about five gallons—and empty it into the sump pit. If water comes out of the drains, it means the clog is cleared. If the water is still pooling in the pit or it drains slowly, you might have a partial blockage.
Reconnect the Sump Pump

Again, fill the sump pit with about five gallons of water to test that the pump works and is attached properly to the discharge lines. Once the pit is filled with water, it should activate the pump’s system to drain the water. If the sump pump is not working, you may have reinstalled it incorrectly or the discharge lines could still be blocked.
DIY vs. Hiring a Pro
Unclogging your sump pump may seem like a messy, complicated job that’s best left to the professionals. But, if you possess some DIY plumbing know-how, you can easily unclog your sump pump yourself. Plus, the DIY costs are minimal, using tools and supplies you likely already have on hand.
However, some circumstances may require outside help from your local sump pump repair professional. For instance, your discharge lines might have blockages that are too far to reach and can’t be cleared with a drain snake or wet/dry shop vac. Or you may have trouble reinstalling your sump pump, or discover you need a new sump pump altogether. The average sump pump installation cost is $1,275 and ranges between $640 and $1,980 depending on labor and the type of pump you need.
Frequently Asked Questions
How long a sump pump lasts depends on how often you use it, the type you have, and how well you maintain it. In general, the average lifespan of a sump pump is around 10 years. You should get at least seven years out of your sump pump unless you live in a high-risk area that is prone to regular flooding or you neglect to maintain it properly. With annual inspections, tune-ups, and repairs by a sump pump specialist or plumber, your pump could last a couple of decades.
Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it.
Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.
There are several things you can do to maintain your sump pump and prevent sump pump problems. For instance, keeping a lid on your sump pit goes a long way in protecting your pump system from silt, sand, dirt, and other debris. When water drains from the outside, such as along your foundation, or with melting snow, water runoff often brings sediment with it.
Also be wary of corrosion, particularly if your sump pump system is made of metal. Keep an eye out for rust and have it inspected regularly by a plumber or sump pump technician.
