How To Clean A Sump Pump

by Ian Haynes

Sump pumps are submersible devices installed inside a sump pit dug at your home's lowest point, like the basement's crawl space. Even though it is a small addition, it is quite important and prevents your basement from getting flooded.  

However, this household appliance requires regular maintenance and cleaning to ensure it functions properly.  

That is why this guide is here to help you understand how to clean a sump pump and keep it maintained. 

Your sump pump must also be cleaned at least once a year for it to work properly, preferably right before the winter starts. Contrarily, sump pump maintenance should be done in spring, right after snowmelt. Because it is during those days, your pump will be working hardest.  

However, this annual maintenance is never enough to ensure that your sump works properly and efficiently. A regular system check-up is also a necessity. You must remove any loose debris you find on the material and ensure that the sieve is clean at all times. A clean sieve ensures that water intake is better protected.

How To Clean A Sump Pump (Best Way For Different Parts Explained) 

Things Required 

Before we discuss how to clean and maintain  a sump pump; here are the materials and items necessary to clean your sump pump: 

  • Plastic sheeting or tarp 
  • Tool to scrape off debris 
  • A big bucket 
  • Garden hose for cleanup 
  • Dry/wet vacuum  

Step By Step Instruction 

Before starting the cleaning process, ensure you take safety precautions. Always turn off the power on the circuit breaker or unplug your sump pump. Also, ensure that no one else in the house is using any appliance that may potentially drain in the sump pit, such as a washing machine or the basement water draining in your sump pit. Furthermore, always ensure that you wear protective gloves while handling gray water. 

Prep the cleaning area and gather all the above supplies and then follow the below steps: 

  • 1
    Disconnect And Unplug The Sump Pump 
    Disconnect and unplug the sump pump from the discharge pipe. Most pumps are joined to the discharge pipe via a rubber sleeve. Employ a screwdriver to loosen it and then pull it off.  
  • 2
    Remove Pump From Basin 
    Once disconnected and unplugged, remove your pump from the basin. To drain it completely, hold it above the basin. If you are worried that this will make a mess, put your pump inside a bucket so it doesn't drip on the floor.  
  • 3
    Clean The Pump 
    Use a clean rag to clean the pump's exterior. Scrape away all the grime with a scraper or a scrub brush. You also have the option to take it outside and rinse the pump off with a garden hose. 
  • 4
    Drain The Sump Basin 
    Use a dry-wet vacuum or a bucket to empty your sump basin. Furthermore, remove any stones, dirt, or gravel from the bottom of the well. If not removed, they can clog your pump and increase the chances of your pump not working when you need it the most.  
  • 5
    RemovAnd Clean The Grate 
    If your sump pump is on a grate, remove it and clean the grate as well. You can spray it with a garden hose or wipe it down via a clean rag.  
  • 6
    Clean The Sump Pump Basin 
    Clean your sump basin walls via a clean rag to remove grime and dirt. While it might never be spot-free, ensure that all the drain holes are clear. When you clean your sump pump basin, it will also help you get rid of any foul odors.  
  • 7
    Put Sump Pump Back 
    Now that your sump pump is clean, you can replace it. If your pump was on top of a grate, put it back also. Ensure that the pump is in the correct position and level so it works. Furthermore, the float arm must not touch basin walls and move freely.  
  • 8
    Reconnect Discharge Pipe 
    Reconnect your pump to the discharge pipe and ensure that your sleeve is appropriately tightened. Even though you must avoid over-tightening the clamp, ensure that it will not leak when the pump starts to run.  
  • 9
    Plug-In And Test Pump 
    Plug your pump back in, fill the basin with water until your pump switches on. Then, observe the pump run to ensure there is no problem.  Also, note the date you cleaned your sump pump and keep it within reach for your reference. You will also want to add it to your home maintenance list.  

How To Clear A Sump Pump Blockage? 

When a sump pump functions correctly, it serves a significant role in your home maintenance, especially during wet weather. It will remove water from the basement, crawlspace, or any other low area that might otherwise flood. Conversely, when your sump pump fails to remove water effectively, either the sump pump inlet or outlet pipe is clogged.  

Here are steps on how to clear sump pump blockage: 

  1. 1
    Inspect the discharge pipe outlet. Based on the position in the landscape, it can quite easily be clogged by dirt, debris, a tennis ball, or any other object 
  2. 2
    If there is something plugged at the end of a hose or discharge pipe, remove it 
  3. 3
    Unplug your sump pump and the float from the electric outlet 
  4. 4
    Remove the sump basin lid 
  5. 5
    List aInspect the small opening or screen when water enters your pump. Use a flashlight or headlamp to examine the pump when it is still in the basin. If you cannot see the pump intake clearly, lift it out of the pit, set it on a tarp or the bucket if your flooring material is water sensitive. Element
  6. 6
    Clear the inlet of any debris 
  7. 7
    Scoop as much silt or debris out of the sump basin as you can. Wipe any residue or dirt clinging to sump basin walls 
  8. 8
    Place the sump pump back inside the basin and ensure that it is level 
  9. 9
    Plug the sump pump back inside 
  10. 10
    Pour around five gallons of water into your sump basin to check the pump. Observe float, trigger the on/off, and ensure water efficiently exits the basin.  
  11. 11
    Pour another five gallons of water into the basin and once again monitor your pump's actions. If your system effectively pumps the water out of the sump basin, then the clog has been cleared
