Review title: Didn't Last Very Long
Product review: I do all my own plumbing. My H770-22 lasted only 4 years and then started leaking. It was a subtle drip that was not noticed for several weeks. The first symptom was the long time it took to dispense hot water. The tank was in the back of the sink cabinet and created a lot of mold and a big mess. I called Insinkerator and went on line. From what I can find out the H770-22 is no longer manufactured and has been replaced by the H770-SS which has a stainless steel tank. The H770-22 uses a plastic tank. Not sure if my replacement instant hot water system will be the H770-SS or the a Waste King H710-U-SN. The Waste King has better overall reviews - Insinkerator has already fooled me once - probably most of the complaints found here are for the H770-22.
