InSinkErator H-990 1/2-Gallon Instant Hot Water Dispenser

I have installed Sears units and other In-Sink-Erator units and I will not install this model again. It has a very poor connection between the hot water unit and the dispenser. The nylon nut that secures the 1/4 copper tube to the hot water unit does not work. Or should I say it does not work when you are lying on your back under a sink with limited mobility! I called 1-800-558-5700 and asked them what to do and they said to keep tightening it until it stops leaking. The directions however say tighten it finger tight and then turn it with a wrench no more than 3 turns or it may crack the unit. And by the looks of the water jacket it will crack.

This is a new design the older models sealed this connection. I guess in the efforts to save 12 cents on a brass fitting quality has gone out the window.

I own this unit. In fact I've owned about 4 of these units. Unfortunatly they've all been on the same sink in about a 2 year period. When they work, they work great. No waiting for water to heat up on the stove for instant coffee, cocoa, tea, oatmeal etc. The first two units just stopped heating after about 3 or 4 months. The third unit was just very noisy. The 4th is still workinig great after 2 whole months. Luckily they failed within the warranty period so they were replaced. I'm not sure if the problem is from being on well water or not. My water is filtered but not softened because it's not that hard. Instant hot water is nice to have, I'm just not sure this is the right brand to buy. I don't think I'll buy another in-sink-erator if mine ever outlives the warranty!

Unfortunately I did not notice when my H990-2 insinkerator instant hot water dispenser started leaking so I have damage to my kitchen cabinets. When we noticed some water under the sink I dryed the cabinet and placed some newspaper on the floor of the cabinet. It quickly became apparent the the hot water dispenser was the culprit. I spent some time searching for complaints and found quite a few customers having leak problems. I will be calling insinkerator tomorrow to complain, but I am beyond the warrantee period and don't expect much sympathy from Insinkerator based on what I have read from others experiences with Insinkerator customer service. I won't be replacing the dispenser with an insinkerator as I don't want to be monitoring the unit regularly. I guess it's back to the stove or microwave for tea and coffee.
