Rated 2 out of 5 by from The 149.00 leak I am quite handy and when my unit leaked all over the inside of my cabinet I called the company and was told that my unit was manufactured in 2008 and I was out of warranty. I went ahead and opened the unit and found that a simple rubber hose that brings hot water from the tank to the outtake valve was split and called the company back to order a part that shouldn't cost more than a few dollars. I was told that I needed a whole new unit which they offered at a discount. I can't believe I needed to buy an entire unit for an 8" rubber hose. That is NOT what I call customer service.

Rated 2 out of 5 by from Oversize Neck Installed in granite counter that had 4 previous similar units. The hole was a standard 1.5" and was never a problem in the past. Unfortunately, the threaded plastic neck of the new unit that goes through the counter was too big for the hole and the metal washer that was supplied. If the neck had been about 1/8" smaller in outside diameter, the job would have taken about 10 minutes or less. The old unit came out very easily. By the time I realized that the new unit was too big for the standard hole, it was too late to remove it. I had to force it through with a block of wood and a hammer. Having done that, I'll probably never be able to remove it without doing serious damage to either the unit or the granite. I had to enlarge the hole in the washer with a file by about 1/8" to go over the threaded outside of the plastic sleeve. That's a waste of valuable.time. Stupid design mistake that should have been caught. Doesn't anyone do a test installation to see if everything fits correctly?

Rated 5 out of 5 by from Love it I use this all the time, as a tea drinker, it makes getting a cup of tea quick and easy. I also use it to soak dishes and heating up water. This is the est thing for a kitchen. It also looks great in the kitchen.

Rated 1 out of 5 by from Product works w/ease but the hot water tastes terrible. This is my 3rd unit in 6 years. Somehow they always start leaking at base of unit. This is the 1st time I find myself unable to drink the water due to offensive smell & taste.

Rated 4 out of 5 by from Review performed after Nozzle was replaced In the end, the system performed just fine. We had an issue out of the box with the nozzle - it sprayed/spurted hot water all over the place regardless of temperature setting. A no cost replacement was quickly supplied.

Rated 5 out of 5 by from Couldn't live without it We have had an Insinkerator hot water dispenser for more than 20 years. When we moved and the new house didn't have one, it was one of the first things we changed. I'm happy again!

Rated 5 out of 5 by from Replacement hot water tank My 10 year old insinkerator started to put particles into water so I bought the newer tank. Removing the old tank and installing the new tank took literally 10 minutes. However, I didn't install the filter which is a new addition since my previous installation as the diagrams were not clear to me. I have an engineering degree and spent over 30 years working in nuclear power plants but the diagram was murky at best so, since our water supply is very clean, I didn't install the filter. Overall, this is a great product and highly recommend it.

Rated 5 out of 5 by from Have to have this I have moved quite often and always install a hot water tank. Sometimes I have installed the hot and cold insinkerator if the refrigerator doesn't have a water dispenser. My recent move had no hot water dispenser so I immediately ordered one. It takes forever for my kitchen sink water to get hot so now I have the hot water dispenser to soak my pots, clean items and always to get a cup of tea!

Will this tank work with the Ready Hot RH-F560-CH Dual Lever Faucet for Hot and Cold Water?

Want to replace tank but don't want to purchase a new faucet.

I'm replacing a SST-FLTR ISE Hot water tank w/f - 201 Filtration L/Dispenser. Can I re-use the same hook up hoses?

Asked by: jsimari
Hi jsimari, This is Belle from InSinkErator Customer Service. The three tubes that are connected on top of the SST FLTR tank are part of your hot water faucet assembly. If you are replacing the SST FLTR with the HWT-F1000S, and you will be using your existing faucet assembly, same tubes will be used. The F201 filter system that comes with the SST-FLTR uses an incoming supply line that is 3/8 inch tube. This is attached to a 3/8 inch incoming supply valve. The F1000S filter system that comes with the HWT-F1000S uses a 1/4 inch suppply tube and requires a 1/4 inch supply valve. If you will be replacing the F201 with the F1000S under this condition, you would need to either change the incoming water valve to a 1/4 inch valve or use a reducer to take it from 3/8 inch to 1/4 inch. If you will replace the tank assembly only, and you will use your existing F201R filter system and your existing faucet assembly, you do not have to change anything. If you have any other questions, you may contact the Answerline at 1-800-558-5700. Thanks.
