does this come with the flush valve?A. The Kohler K-4329 does not come the commercial flushometer valve and is not ready for use without this. A flushometer valve for this style of toilet will have to be purchased separately prior to installation.
will the K-4636 softclose seat work with this toilet?A. The Kohler K-4329 will work with the K-4636 but it will not be a perfect match, the seat is a little bit smaller then the bowl.
