What i would like to know is: Can i pour bleach in the opening to clean it? Thank you. Kathleen
I wouldn't pour anything into the actual pump. Here's a link on cleaning the pit:
Hi Kathleen, here are a few posts that can help:
Assuming the sump pump is for a basement drain or something like that. Bleach of white vinegar can be poured into the sump. Disable pump for a while and then let it run to pump out the solution and add more clean water to flush.
I agree, vinegar or bleach should work just fine.
Yes you can. You might want to check with the manufacturer first

I would try vinegar first. Then bleach if you feel necessary.
