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 3 out of 5 by from More difficult than it should be The hose size changed from the previous model to the current one (3/8 to 1/4) which was not mentioned when I ordered on the phone. I would not have bought the filtered one had I known bc the attachment to the cold water line required by the filter necessitated buying an adapter at the hardware store. The instructions are geared toward the non filter units so it did not say to turn off the cold water which caused me to flood the kitchen before getting it turned off. Rookie mistake, but I fix most things in the house and this was not in the instructions although they did say to turn off the hot water supply.. I called the support line twice to get help with the adapter needed in converting hose size from the old to the new and each time the help line was absolutely useless telling me to call a plumber which I finally did. The enclosed hose was very short so I had to also buy a new one.

Rated 1 out of 5 by from Great customer service; terrible product I've had 5 of these in the last 8 years. The product only lasts 12-24 months then dies. There is a warranty but you can only get so many replacement tanks before you have to purchase another one.

Rated 3 out of 5 by from Not long lasting My tank only lasted 4 years. Has been leaking for over a year. I would expect a "stainless steel" product to have lasted longer than 4 years. Not only do I have to purchase a new "stainless steel" tank, but since they changed the tube size I have to purchase new filters. Not happy!

Rated 5 out of 5 by from Replaced 6 year old one easily Previous InSinkErator lasted only 6 years, which is disappointing. I hope this one lasts at least 10 years.

Rated 1 out of 5 by from At best this product is convenient to use. This is my third on demand hot water dispenser. Should have learned my lesson with the first one. Be prepared to replace after 5 years or be prepared to find a kitchen cabinet full of water or worse. First 2 leaked within the 5 to 6 year period. New one only has 1/4 feed while the first 2 had 3/8 feed and better flow. New prefilter much longer and takes up more room in sink cabinet.than the first 2. I doubt that the clear nylon hose from the heater to the expansion tank has been insulated to keep from splitting. This is an issue because the hose is in direct contact with the heater tank and over a period time the hose hardens and splits because of heat. When tank heats up , the water going to the small expansion tank leaks out the crack in the hose. Again I'm not sure if a heat shield has been added but i doubt it. I did notice the new heater has no drain on the tank so I have to assume that was an issue in the past. Overall it's very convenient to use but it's a very expensive ($400) tea kettle whith a very short life expectancy. ,

Rated 4 out of 5 by from This product lived up to its promises. The water is very hot and immediate. We really like the convenience of the instant hot water. The only thing that I would add is you need to run a gallon or so through after installation. This to filter out any of the manufacturing tastes.

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.

do I need to pipe in hot and cold water or just cold only?

why is it sputtering?

hot water is hot but it spits and sputters
Asked by: BKing
This is normal operation. I believe it is from the pressure build up in the system. You will also notice that it drip and sputters periodically even when not in use.
