We have owned three Insinkerator heaters. They have all been quite dependable but the hardness of our water eventually does them in. Always before we have had a simple, small, Hot Water only faucet. This time, we got a new deluxe sink and a very deluxe Delta faucet in the middle of the sink.. So, we decided on a very deluxe Hot and Cold Water Insinkerator faucet for the right side. The physical shape and the metal finish of the two faucets match well. The filter fits easily under the sink beside the heater. It is good to have filtered hot and ambient temperature water readily available. For filtered and actually cold water, we use the refrigerator.. I did not install it. A plumber did. It did not look terribly easy.
