IN-SINK-ERATOR/MASTERPLUMBER H CONTOUR SS Chrome Hot Water Dispenser

I didn't read all 435 reviews of this product, so perhaps this comment has been mentioned already. Or perhaps the design has changed and my comment is no longer applicable. We had had four of these units over about 12 years. Each had eventually leaked badly under the sink after about 3 years. After this last time, my wife was ready to call it quits. With nothing to lose, I disassembled the unit to see what the problem was. I found a design flaw--a section of polyurethane tubing ran adjacent to and was touching the heating unit. With time, this section of tubing had become discolored and brittle from the heat and had cracked, causing the leak. I removed the damaged section of tubing and spliced in its place a section of copper tubing. We have continued to enjoy this same unit for another 5 years so far without any hint of a problem. Many reviews of this otherwise excellent product have mentioned that their unit had leaked, and I wonder whether those leaks could have been due to the same issue. Routing the tubing elsewhere, using metal tubing instead of polyurethane, or placing insulation between the tubing and the heating unit would prevent this problem. Or perhaps the design has changed and this is no longer an issue.

Make sure your outlet under the sink has 2 working plugs. Works good. We needed to turn heat down the first time.
