Before I head blindly to Lowe’s to find some, can any one give me a heads up. I have a hole my water softener brine tub that needs plugged. It’s on a relatively flat surface. The tub seems like a big rubbermaid tote made of translucent white plastic. I’m thinking I can just cut a chunk of milk carton or OJ bottle plastic and just stick it to the inside. Maybe I’’m being overly cautious, but this is our household drinking water. Would hate to make the dumbass headlines when a family of five is found dead of superglue poisoning.
