Cleaning the Drain Pipe
Cleaning the drain pipe is just as important as cleaning the pump and basin.

Step 1 - Disconnect from Power, Battery and Alarm
The first step is properly disconnecting your pump from the electricity and other accessories like back up battery and alarm. Things are going to get wet and there will be standing water so we don’t want to damage the internal electronics – plus we are going to need to wipe down the entire unit with bleach or vinegar. The last the you wan’t to do is ruin your pump while doing regular scheduled maintenance and cleaning.
Step 2 - Disconnect from Discharge Pipe
The next step is to disconnect your pump from the discharge pipe. Carefully loosen any attaching screws or fasteners and the pump and pipe should slide apart.
If you feel resistance it may be a sign of moldy buildup in the pipe and pump exit. Make sure to clean this area with bleach or disinfecting vinegar to kill growth and keep it from coming back.

Step 3 - Remove from Pit
One common mistake new homeowners make is trying to clean their sump pump while it is still in the pit. Cleaning the pump inside the sump pump pit only moves around the mess.
If you want to get your pump and basin truly clean the best way to do it is put it inside a trash bag and take it out into the backyard. Once in the backyard you have a lot more room to clean plus you do not have to worry about spilling grime on your carpet in the basement.
Step 4 - Scrape Sludge and Rust
Once you are outside it is time to start cleaning your pump. The best way to start is use a sponge, warm cloth or even a flat head screwdriver to scrape away any mold mildew or material build up’s. If there is too much to remove by hand you can blast it off with a garden hose.
Keep a close eye out for rust or other metal corrosion‘s – especially near the power supply and pump body. If you let a metal pump rust your will significantly decrease its lifespan!
Step 5 - Disinfect Basin
Disinfecting your sump pump basin is just as important as disinfecting your pump. Do Paris and other build up can collect overtime in the bottom and sides of your sump pump. Don’t forget to give your cover a good wipe down, especially in the underneath cracks.
Step 6 - Disinfect Pump
After you have removed all of the mold and grime it is time to disinfect the pump and pump basin. Using bleach vinegar or other disinfectant wipe down the exterior of the pump. Make sure to disinfect the entire unit as mold mildew and other germs can live in cracks and crevices.
Also make sure to clean other parts like the check valve and float switch.
Step 7 - Clean with Shop Vac
Use your Shop Vac to remove remaining water and debris from the bottom of the pit. Cleaning all of the Leftover water and pump particles by hand is nearly impossible – with a a shop vac you can’t quickly and cleanly get your pump pit looking like the day you bought it. Always remember to empty the shop vac when you are done. Remember it will be full of dirty water mold mildew and palm particles so you do not want to let it sit overnight
Step 8 - Reattach and Test
The final step in the cleaning process is the reattach the pump. Start by reattaching the discharge pipe, then add any supports and finally plug in the alarm and backup battery to the power source. Once everything is in place fill your basin with a few buckets of water and make sure the pump works!
