InSinkErator Instant Hot & Cold 2 Temperature Water Faucet Dispenser Tap, Chrome

I have had the faucet for somewhere over 25 years. It has worked almost almost flawlessly throughout, and still looks as good as the day I bought it. The cold water valve no longer locks in the "on" position, but there is an easy work-around: just put a cup or bottle of dish soap on the lever to block it open when you don't wish to hold it open. We use it 2-10 times daily. Hot tea, instant coffee, or perhaps melting frozen veggies with hot water prior to going on the stove. I also use the hot water side to melt grease off of dishes. It has outlived 3 of the under-sink water heaters. Other reviewers report a short life span on the parts. Perhaps there has been a change in quality over the years. I'd give it a full 5 stars, except for the absence of parts availability. Despite its age, so far as I am aware, this is the only hot water dispenser valve which also dispenses the filtered water in hot and cold, so they get 5 stars on "innovation". I guess innovation counts, regardless of how long ago it was done. There are more little tubes under the sink than you might anticipate, and the valve installs cleanly in the hole where our flexible dish sprayer was located. It seems to have been designed to fit that traditional 2nd hole in the sink. This necessitated installing a new sink faucet with sprayer features built in to the raised spout. Overall, that has proven to be a big improvement also.

Was a replacement for the same model. On the previous unit, the hot water handle mechanism had broken inside, and water ran continuously. Consequently, the replacement faucet was an easy install. One warning, however, is that there are two copper tubes that project downward from the faucet under the sink. Compression sleeves and nuts are not included with the faucet. Certainly inexpensive enough, but adds one additional trip to the hardware store. Not sure why Insinkerator did not feel compelled to include such simple hardware. Many other plumbing fixture companies include various different pieces of connection hardware for their products to make it as easy as possible for the DIY'er. One other comment, initially the faucet dripped despite a thorough flushing of the unit, as well as pushing and pulling the handles (hot and cold) on and off in an effort to clear any debris that might have caused the valve inside not to seat correctly and shut off water flow completely. Then, two days after the install, it stopped dripping. So, be patient with your install. You probably did it correctly, and tincture of time was required to work out any debris or air bubbles that might be causing problems.
