We recently moved into a house with a sump pump pit and a sump pump in the basement, which is new for us. The sump pump is located in a utility room 8.6' by 11', which has a door, but even when closed, it does very little to abate the sound of the sump pump. The previous owner had put a couple of plastic strips with some bricks over the hard plastic cover to deal with the splashing when the pump ran.
It was noticeable when the sump pump ran almost anywhere in the house. The sump pump pit had what I would describe as a black, hard plastic and hollow cover. It had openings for the pipe and hoses to run into, and while it would prevent anything from falling into the pit if anything, it amplified the sound.
Looking for a solution, I came across this acoustic foam, which could help quiet things down. There was enough width and length for me to double-lay a cover over the hard black plastic cover of the sump pump pit, which had a diameter of around 19 inches. The other critical benefit of this foam, especially for the application I used it for, is that it is closed cell, which means it's waterproof and won't absorb moisture.
A word of caution. The adhesive is extremely sticky, like super glue, even to bare skin, so be careful. There is also no adjusting. If you place it wrong and have to pull it off, it will rip the foam. Otherwise, this acoustic foam is very easy to work with.
I cut the foam 22 inches long to accommodate the pit's diameter and have some extra so it would fit around the edges when pressed in. I pushed it into place and marked the lines on the kraft paper backing where I would need to cut for the pipe and hoses. It is very easy to cut using a pair of scissors. Once I had the cut perfect, I put it back to back with another piece of foam and cut the same lines for the pipe and hoses. I then removed the backing from both pieces and stuck them together to double the thickness.
I then repeated this for the other side of the pit so that the two halves would overlap by a couple of inches when I laid them down over the existing plastic cover.
It worked out great. It's a nice, clean look and immensely helped dampen the sound. If before, the sound of the sump pump running was a 10/10, it's now more like a 5/10. When the utility room door is closed, you also can't hear water running into the pit anymore. I would highly recommend this acoustic foam. It's a great value.
