Bests & Worsts Reviews from Amazon

This is the third InSinkErator hot water system I've had to replace in five years. The first one had the handle break off. The 2nd one, from just over a year ago, was the HOT100 model (very similar to this one) and the push button switch jammed and we could never unjam it to turn off the flowing hot water. The tank was still good so we decided to take a 3rd chance and bought this newer twist handle model to replace the HOT100 because we could keep and use the old tank still installed. This was a mistake to trust InSinkErator a third time. We swapped out and replaced the faucets fairly quickly and then turned on the water. Sure enough, water starts spraying from a small pinhole leak under the sink where the copper tubing is welded inline with a blue PVC tube. I had to uninstall the faucet to see that the FACTORY WELDED copper joint had a small pinhole crack. POOR quality work. Not only that but I compared this HOT150 design with the older HOT100 design and InSinkErator tried to save two dollars per product by using this crappy factory weld job instead of using the more secure and safer double copper compression fitting like on their older HOT100 model. Essentially, they reduced their manufacturing costs but then passed the higher risk of product failure along to the customer. You can take your chance with this model. It is a great design ABOVE the sink. However, below the sink is a risk. If you happen to get a good one that doesn't leak then make absolutely sure that you never bump your undersink garbage can or other items into the copper piping hanging below the back of the sink. You're likely to cause a crack in the WEAK copper welding and possibly create a new water leak. Oh, and plan on a possible quick drive to the hardware store. InSinkErator Quality Control didn't include the necessary copper compression fitting for us to hook this up right out of the box as instructed.
