The lower part was long, but I managed to attach the bellows hose as it was. The joint was not filled with sealant, but there was no water leakage.

Although I am a complete amateur, I was able to easily and surely replace it with careful drawings.

Replaced and repaired due to damage to the wash basin of the house. I bought this product because the metal ring at the top was broken from the resin part under it and it came off, so the minimum unit part was this product. It will break in about 5 years, so to be honest, I think it will break in a few years.

Due to the deterioration of the resin, water leaked and I searched for a replacement part, but I could not find it at the DIY store and it took time to order it, but I could get it quickly with Monotaro. Since it was not a completely compatible part, I cut it partly to shorten the length and repaired it with self-bonding tape, but there is no problem.
