I have a sewage ejector pump system that has issues with sewer smell. So, obviously it needs to be sealed up better. But I cannot seem to remove the bolts/screws holding the lid down, all four of them spin but do not come out. I've attached a couple pictures, some help/advice is appreciated! (Anyone recognize the type/brand ? EDIT: The lid is about 20 inches across)
