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 1 out of 5 by from Not Happy Installation was easy except the change in water line size from 3/8 to 1/4 neccessitates a coupling if one is replacing an older model. Also the new heater seems better designed in that some of the outlets that leaked in the older model have been eliminated. However the whole system is now prone to occasional dripping and despite poor response/discussion with your technical staff,water pressure has not changed and there are no blockages etc of any kind. Not sure what this is related to but it is not satisfactory.

Rated 3 out of 5 by from I really like Instant Hot water- have had older models. This one has a flaw though. It sputters hot water on the hand when it is used. The plumber told me that it was because the water is hot, it creates pressure and then when it is opened their is air that is forced through the faucet and so that is why this happens. This is not a good feature. If this did not occur I would strongly recommend it and give it 5 stars.

Rated 5 out of 5 by from Works well Should include quick connect since in my case I was replacing an older unit and fitting had served it’s time.

Rated 1 out of 5 by from Never gets hot enough I ordered this system to replace older model that failed after 4 years. The replacement despite calibration never gets above 175F at MAx and 144 at Min, Specifications call for 160-210 F . I sent the product back and re ordered another unit. Unfortunately new unit seems to have same issues. Used mainly for coffee which needs close to 200F to be of any use. Extremely disappointed. It looks like my H3300 indulge tap will soon be removed and become a soap dispenser ...

Rated 1 out of 5 by from Awful Experience Why sell a product that needs a proprietary quick connect part that cannot be found anywhere? Just charge us a few dollars more and save the hassle of having to try to find it. I guess I am going to have to return my item, I can't get it to work.

Rated 4 out of 5 by from Love the convienence I have been purchasing and installing (licensed plumber in 2 states) your instant hot's since the early 1970's, not only for clients, but in every residence that I have had too. I am at my current address for over 16 yrs. My first unit here lasted almost 13 yrs, but unfortunately the second one only lasted just over 3 yrs., and now I am on my 3rd tank here. I hope that this one lasts as long as the first one or more. Thank you.

Rated 3 out of 5 by from This is noisier than I expected. Noisier than I expected. I did not install so cannot comment on that. It takes forever to get hot water at our kitchen sink so this was a nice addition.

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.
