We have used our sinkerator for 7 years. We depend on it daily. We recently had to replace the upper portion that dispenses the hot and cold filtered water. For some unthinkable reason there is a restrictor in the cold. This makes no sense at all and is frustrating that the cold water comes out so slowly. When you need to fill a pitcher you are standing there for what seems forever holding it under this tiny faucet with a restrictor in it. This is just plain dumb. Also, we had to have a plumber install it. It did not look like he was having an easy time of it.
