Question: Just had Insinkerator installed and plumber left with all printed material.  I would like a copy of warranty.  Any ideas?
Document: We have 3 of these garberators installed in our house. They are built solid, and appear to have a great on site warranty. The installation is extremely easy, as long as you go to home depot and pick up in the elbows and plumbing material to cover every angle. Once your done, you basically just return the rest of the items you didn't need.
I've had the InSinkErator Evolution Essential for about a month and its certainly as quiet as they advertise. When its on and the rubber stopper is placed in the drain, there's a slight hum and that's it. It's fast and thorough on &#34;normal&#34; material. Can't say how easy it is to install because I'm incompetent when it comes to handywork, so I got a plumber to put it in.
Quiet sums it up. That could be a problem I suppose. I left the sink once and left the disposal running. I had already turned off 5 water. Fortunately, my wife heard something. It was very easy to install. ..much easier to install than the one I installed 13 years ago. It was also an Insinkerator...not this same model but an earlier version. Love them!! !
Just like clock work. Ordered this disposal, it arrived in four days and was installed with one tool and a flashlight in 40 minutes. Literally cost one-third of what buying one in town and having a plumber install. Hooray Amazon.com and thanks to customer service at In-sink-erator for recommending this model to replace our old one. Really, really quiet, too.
I have installed 3/4-hp disposals in three kitchen projects in the past 20 years, and I highly recommend spending the extra bucks. I have never had one of these units jam, and they are great for disposing of items like chicken bones that would otherwise smell up your trash.
I replaced an old 22 year insinkerator that quit working and made noise like a jet engine. The new installed quickly and cannot be heard running. Happy Happy Happy!
It is really quiet and I like it so far and I don't know how long is the warranty of it. I heard it 8 yrs but I was too busy to read the warranty. So far so good.Thanks.
This disposer has been a good one. The only problems I have had was a wobble once..ran some ice through it and it took care of it. Then a came a little loose once,  this could have been my fault, not sure. The thing I like is that it is very quiet compared to our last one and that it has a 6 year in home warranty. We have had ours for about 3 1/2 years. Pretty good disposer.
From start to finish, it took 15 minutes. It was like changing out a very heavy light bulb.It's far quieter that the Badger, and with a 6 year in house warranty, I know I'll never have to touch it again (well, at least for six years). It's worth the extra money (as opposed to the baseline Badger) to get something that actually works, and the install is a breeze. Very well thought out for all users. Doesn't take technical expertise.
My plumber suggested that I buy this unit. Let me tell you, compared to the cheapies that I have had in rental houses, and apartments, this thing is like a Bentley. I can not believe how quiet this machine is. It seemed to me like my old one was constantly being plunged out by me at 11 PM and then getting mad because my wife put some egg shells or noodles down the thing. Now?
Answer: yes
