I received the High Arch Faucet yesterday and installed it myself. The most difficult part of the process was removing the old faucet. I used the three hole installation with a fourth hole for the side sprayer. The instructions are clear and easy to follow. The hot and cold water are attached via flexible connection or a hard connection. It is your choice. The sprayer is attached via a snap connection which was very easy to attach. It took me less than an hour to install. As I said removing the old faucet was the difficult part. I have only been using it for one day but it I'm sure it will last a lifetime. It also looks nice.
