So, I bought a California Split with an unfinished sub-basement (aka HT). Anyway, the sub-basement has a drain in the middle. I want to finish the room as and HT, but what do I do about the drain (and the fact that the floor sinks in around it)? It wouldn't bother me (I guess) if the floor around it were flat. Do I need to worry about it? The floor does have a sump pump, should I really worry about the drain? Right now, I'm thinking I should just carpet over top of it and work around it. What do you think?
