I agree to me it is designed to fail. I have had one for a about five years and replaced it once but having to repair leaks about every 1.5 years or so. In the end I designed a leakage tray that drains into the sewerage piping. Just really annoying, expensive system that does not last.

This is a crap house product. Its designed to fail after about a couple of years use. The tank consists of two stainless steel sections bolted together with steel bolts all the way around. The mild steel bolts appear to have a rivet shape top and nut below and these bolts rust all the way to failure. See picture of a unit i deconstructed as evidence.

We bought an Insinkerator boiling water unit in 2006 and it lasted 2 years. In 2009 we installed one in our new house, it also lasted a few years before the plastic tank split again. We were assured by Insinkerator that they now have stainless steel tanks so they will not split, so we installed a replacement unit. On the weekend our safety switch was triggered which left us with no power at 9:30 at night. The cause? you guessed it. I am not buying a fourth one. Something should be done about companies that keep manufacturing a product that does not last long enough to justify its cost.

First tank lasted 3 years, second is 3 years 3 months old and is leaking now too.
Both damaged my cabinets.
I paid for the first replacement but no way will I pay for this one.
I’ll keep you all informed of my progress.

We bought one a many years ago.
It started to leak just out of warranty.
Made of cheap nasty plastic.
Will not be purchasing another one in the near future. (Unless the price was right).

One thing you can say is that they are consistent, I have had 2 units, each lasting 16months, the second one a replacement, failure mode identical on both. Leaking from the boiler unit gasket. The one thing about a consistent failure its easy to diagnose, yet what surprises me is that the warranty bill must be huge and why any company would not want to fix this issue is beyond me. Basically the flanges on both halves of the vessel start to creep under pressure and the gasket looses compression. So either use thicker steel (which is pennies) or add more screws along the gasket perimeter. Phil CEng

I liked its elegant design and was fairly easy to install. However, after a couple of months, it started to leak from the base. I was able to fix it with the help of a couple of tools but it wasn't a permanent solutions. After sometime, it would start leaking again.

The spout always spurted badly which I replaced myself, and even after the new spout it still spurted badly, sometimes burning myself. then it started leaking and after investigation discovered that this unit was designed to only last 2 years, the temperate button on the front of the unit the spindle sheared off, it leaked from the bottom of the unit which is impossible to repair. Sadly this unit is designed to to fail!

This is our second unit, same issue as the first, yes tank leaking after 21/2 years. I think the concept is great but I will be looking for another option as replacement.

Loved it for 4 years then it started leaking. We thought (ie the plumber thought) it was from the cold water connector at the top. Actually I think it might have been from the tank itself. Same issue as others. It leaked cold water into the cupboard when the hot water tap was on. I love hot water taps but will be looking for another product

Just rang Insinkerator as my 5th tank is leaking after only just 2yrs. All the others lasted about 18mth to 2 years. This is obviously a bad product for it to happen so often and to so many people. Insinkerator in 2002 had to withdraw the tanks for leaking and here in 2017 the problem still exists.
My advice to anyone thinking of an Insinkerator hot water system is go elsewhere as you will have nothing but problems.

I had mine fixed within the warranty period as it was leaking from the handle and hot water was constantly dripping from the spout. Then just after the warranty expired the water tank was bulging and finally gave up. Now I got the ZIp which seems to be working fine even after the warranty period.

This tap was great until a few months ago - so about 5 years in - now everytime I turn on the cold side water leaks out of the hot side.

I have had a GN1100C (steaming hot water only) for over 3 years and it is a boon, never caused a problem. There is a bias to negative reviews being reported and the problems reported by others may yet happen but so far I am happy. One factor may be that I have connected it to a timer, so it switches off while we are at work each day and we switch it off when we are away. Also keep the temp a bit below 'Max' and change the filter yearly.

Fitted approx 3 years ago. It does what it says on the tin. Great product that I've recommended to friends.
New taps available now. I'd probably go for the 3in1 given the choice again. Good price too

First unit lasted 20 months, it was replaced with a new unit (GOOD SERVICE) 2nd unit lasted 17 months. That now leaks, getting in touch again. Only last 18 months terrible.

Had one installed Sept 2011 started leaking 2 years later warranty was just out but was given a replacement no cost, it lasted 3 years and is now leaking so up for $ 450 for a new one, I will get in touch with consumer affairs to ask how does this garbage be allowed on the market. How can a company justify a product that only last till just pass its warranty cost a initially $850 plus installing and only last 2 and a half years. Its a pity as I like the convenience of not boiling a jug but simply having instant hot water

Had my first of these about 4 years ago. It leaked within 8 months. Company sent an engineer to replace the unit. He said I had a dud leaky batch and they were replacing them. Had a second replacement after about 18 months (again courtesy of insinkerator). Customer service very good. My 3rd unit is now leaking again!

We have had two of these Insinks both of them leaked the first one 18 months. The second one 13 months having ton look for something better hope we can find something or we will just have a tap that is useless.

We had the same problem first tank leaked just outside warranty & expensive replacement has now started leaking and don't want to go through all the cost again
Look for better replacement before outlaying more $$$$$ and look for more reviews and better warranty
Filters also very expensive and difficult to replace
