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 5 out of 5 by from Works so far This works great so far. My past experience with these things is that they break down just after the warranty expires, however when you call insinkerator they will offer you good discount on a purchase of a new one (20-40% depending on who you get. Also buy with a credit card that gives you extended warranty protection. I haven’t found another brand and really can’t live without one, so I guess I’m stuck with this.

Rated 5 out of 5 by from Love instant hot water. We are in the era of instant everything, Now I have instant hot water. Makes tea making easy along with so many other things. But, be careful. The water will come out extremely hot. Sometimes if you are not paying attention, it may swoop down to the bottom of your glass and over the other side which, depending on the temperature you have the unit set at, could burn you. Its your choice on the temperature you set it at. No fault on the units design. This unit was installed buy the builder so I can not vouch for the ease of installation or delivery of the unit other than to say it was in when we closed.

Rated 4 out of 5 by from I like the product This is my second inSinkErator system. This one has a very poor nozzle! It squirts water in all directions! My old one was wonderful with a very steady stream of water. My new one has been disappointing!

Rated 3 out of 5 by from tank leaks This is my third unit. All have developed tank leaks. I replaced the first two by buying a new one only replacing the tank. I don't see or can find a place to just buy a tank. I love the use and ease, but they have become very expensive. In reading reviews appears the tanks are the weak ling in the system. They should offer a replacement tank.If I can not find a place to replace the tank I will not spend another $300.00 dollars to just replace the tank. I guess it is back to the tea pot or microwave.

Rated 5 out of 5 by from Instant Hot Water on Demand So far so good for this product. After replacing another brand of this type, my plumber selected this, and I have no complaints. Perfect for a tea drinker or chef who needs hot water fast, it is easy to use and delivers.

Rated 5 out of 5 by from Easy to install. I bought the unit to replace the existing unit. It lasted 5 years. I was happy with 5 years and replaced it with model that replaced that dispenser. It was a matter of unhooking the old one and replacing it with the new one. No tools needed.

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.
