  1. What caught my attention is when you said that some parts of your sump pump must have worn out or damaged when it is making irregular noises. This is something that I will share with my mother because her basement always ends up getting flooded due to a damaged sump pump. She said that it made strange popping sounds for about a minute or two before it totally stopped working a few weeks ago. I will ask her to hire a professional that can replace it for her.
