I use it when I exchange it from a Japanese style toilet to a style toilet. Used over the drain pipe. It is good to be able to deal with either the diameter of the water distribution pipe 100 diameter or 70 diameter. There is packing to make it close to the toilet bowl.
As impressions used, I am satisfied that I can repair without problems. I searched for "patty" and "bolt of horn head for toilet fixation" for repair, but because I did not have it, I bought a set. It is a reason for purchase because the bolt is made of iron with old equipment (Inax made), corroded, the toilet wobbled, and the water leaked. How about setting "putty" and "bolt of horn head for toilet fixation" for repairing for toilet bowl? By the way, there was a setting only for putty for urinal.
