 And putting it into what? I missed the first part. Into the drains. The drains aren't being used. Oh, no, you can use that. Actually, you absolutely can use that. In fact, when I told the other fellow on the mineral spirits to stop the sewer gases from coming up, I didn't mention that, but it was in my head because that's usually what I tell people to use if they're going on, you know, if they're a snowbird and they're going to be gone two months. But, yeah, an RV antifreeze will certainly work in there.
