I replaced my old insinkerator Hot/Cold with the same model. Old one leaked at cold handle. It was over 10 years old. Loved it. The new model has some sort of flow restrictor installed that does not allow the water to flow as good as the old one. It takes almost 20 seconds to fill a glass of water. It was installed correctly. Maybe my water pressure is lower than what the new model is designed for. Thinking on returning it.
