Porcher toilets are not the most common, and they are expensive. The previous owner of my house installed it and it’s been great since we bought the house in 2005. I can understand why they are expensive. About a month ago the toilet kept refilling the tank every few minutes. The original Veneto with the top flush button uses a very different mechanism from what one finds commonly. After a number of phone calls to LIXIL, the new parent company we figured out what part I needed. It works great and Chicago faucet offered the best combo of price+shipping.
