Rated 5 out of 5 by from Can't live without this Boiling water in a pot is not for me so when our instant hot insinkerator died we immediately had to purchase a new one. The design is a bit different but everything else is the same. The only reason I gave it a good instead of an excellent on ease of installation is because the area under our sink is very small and crowded and it makes it extremely difficult to install the insinkerator without having to disconnect the garbage disposal first and then install and put the garbage disposal back together. It's fine if you're familiar with how to do it, but that installation was not for a beginner. I had to hire a plumber to install it. But I couldn't live with boiling water on the stove etc., this has been a life saver on many occasions. Plus it's extremely sleek and modern looking.

Rated 5 out of 5 by from Bought the exact same replacement unit after 6 years of daily service, probably 8 times a day. Great product! I thought It would last longer than it did though. It leaked within the unit and I ordered the exact replacement from Lowe's. No issues through out that 6 years of service.

Rated 1 out of 5 by from It's been a nightmare A previous insinkerator dispenser was in the home when we bought it and worked for 7 years. When It failed, I ordered a new product from Amazon and had a plumber install it. After working while the plumber was there, it began dripping for the next two days. It then proceeded to work flawlessly for 10 days at which time the volume of output declined precipitously. Too late to return, we then called on the 3 year in home warranty service. They came out with a new faucet, but were unable to remove the newly installed one. Currently waiting for the plumber to come and remove the old (new) faucet so the warranty people can return and install the replacement. Will this nightmare ever end?

Rated 5 out of 5 by from Replacement for another hot water dispenser After a lot of research, I chose the Involve H-Wave InSinkErator to replace my old hot water dispenser. Since this was a different manufacture, I was concerned the installation would not be simple. Not only was it simple, I only had to buy one pipe connector to connect the unit to my existing water line. We’ve had the InSinkErator installed for several weeks and it delivers instant hot water for our tea and coffee.

Rated 4 out of 5 by from Mostly perfect This Hot Water dispenser was bought to replace a counter top model to free up some space. While it definitely did that, the only negative, if you can even call it that, is that you can hear the heating of the water throughout the day, while the counter top model we had just kept it at a specific temp without any noise involved. Once you get used to it though, it is not an issue.

Rated 5 out of 5 by from Why didn't we get this sooner!!! Why didn't we get this sooner. It is so handy to have hot water on demand. Perfect for tea and certain cooking activities. It was really easy to install and temperature adjustments are easy and quick. We use it daily.

Rated 5 out of 5 by from Useful and look good Clearly the professional plumber had not install this type before many times, he said the hole side does not fit. I looked at the manual, it has two side, the smaller larger side can be done by removing the smaller size hole. I helped him to install.

Leaking from bottom of the unit

Can't tell exactly where leak is coming from but would like assistance in identifying and correcting the problem.
Asked by: DandY
Unfortunately this has been a recurring problem for me. If it is out of warranty you will need to replace the tank. Be sure keep a bucket underneath for the next time it starts leaking. You may also consider placing a leak detector alarm under the tank. They are fairly inexpensive and may notify you of the leak before serious damage occurs.

Do you sell replaccement parts for the H-Wave SS?

My plumber cut off the quick connect from the blue hose. Do you sell a replacement blue hose as it came originally in the box (with the quick connector installed)? Also, do you sell a replacement ferule and nut for the copper line, where it connects to my existing cold water? Thanks.
Asked by: Drymouth
Customer service will sell or replace the quick connect blue hose. Local hardware (or chain, or plumber supply) store sell the 3/8" ferrule and nut. suggest getting a spare set of the ferrule/nut, these are cheap and sometimes leak if not installed or tightened correctly.

My Involve H-Wave system did not get installed with a replaceable filter. Does it need one?

Asked by: DennisO
A filter helps keep debris out

Very slow dispensing hot water

I have a new H-wave and the water comes out very slowly it also drips a little while it heats up.
Asked by: Bj414
The water does not come out as fast as your main faucet but it should not come out too slow either and it should not drip

Does the new stainless steel tank mean it is compatable with a Kinetico RO system and we do not need additional filters?

Which finish is closest to Brizo stainless steel faucets?
Asked by: Reenierose
I would have to say brushed nickel
