Frequently installers put the trap so high that water stands in the disposal. Often the dishwasher pumps out into the disposal so there is a constant renewal of electrolyte. I have replaced many disposals but never seen one quite as bad as the one in the article."
The trap on my unit is much lower than the disposal chamber. In fact I had to make a 3-inch extension on the drain tube to reach down to the trap. The elbow which came with the unit was not long enough.
Nevertheless my old unit looks just like the one shown here. I still have it--waiting for spare time to salvage the copper motor windings. Probably $5 worth of copper which I can put with my copper pipe scraps until I can get all of it to the scrap metal yard.

Yeah, but when the Hydramatic plant burned down in 1953 and Pontiacs were shipped with PowerGlides and Oldsmobiles and Cadillacs were shipped with DynaFlows, no one said a word, even though us motor-heads knew the two-speed PowerGlides and Dynaflows were clearly inferior transmissions compared to the three-speed Hydramatics. It is possible that the GM execs used that experience to make their decision on responding to the engine shortage.
You would remember this, O_C, but for the young folks' benefit:

Mine lasted about 11 years as did its predecessor. One really annoying thing is the price inflation. I can remember buying these things for $35-40. Now they are around $100. They seem to have gone up much faster than inflation.
Hard to buy another brand. The dealers around here carry only Emerson or InSinkErator and those are really the same product. My previous and current units are both Badger 5s. At least I didn't have to change the under-sink fitting when I changed over.
I filled out and submitted the registration form that came with my disposal when I bought it and just (two days ago) received a survey form. I will have some fun responding to the survey and will cite this website. I wonder if they will respond.
Just took the survey. I couldn't link to this site since the entire survey was check boxes and radio buttons. No place for freeform comments. But I think they know what's going on. The questions ran something like this:
You replaced the unit you bought in 2001. Why did you replace it? Choices included:
Water ran out the bottom
Water ran down the side
Motor stopped running
They did ask if they could contact me and I left them both phone and email information. I'd love to tell them what I think and refer them to this site.
We were at a tailgate party in Austin Texas. These guys had a "redneck margarita machine." It was a Cooler with a disposal mounted on the bottom of it. The disposal output was piped back to the top of the cooler and there was a petcock on the pipe for filling your glass.
Yes, I had to replace the disposal last year after 16 years in our new house. I picked a middle of road from Home Depot. We were also having problems with the vent for the sink and dishwasher. The metalized plastic curled up from the bottom. Could not find a replacement vent cover so replaced the whole vent wye with stainless cover. When the dishwasher ran all the discharge blew out the vent into the sink. At least it was better than going all over the counter top in spite of the WIFEs rag dam. So this went on for quite some time. I even took it apart to verify that the plug was removed from the disposal and I had plumbed it correctly. We lost track and ceased to notice that it is now working correctly. I have not a clue.
You know I bless test equipment. So I guess by the laying on of hands - me working on it - now works. By the way for a small minimum fee I will bless your equipment. I think it would work better if you hold the phone or computer up to your equipment you want blessed.
Slight correction: Hotpoint appliances weren't made by GE (General Electric) but by GEC (General Electric Corp.), a British conglomerate that went through a few trademark infringement lawsuits with the U.S. GE. GEC also owned Plessey Semiconductor, a good chunk of BAE, Marconi test equipment, several holdings in power generation and distribution and, in 1978, purchased the company I worked for: A.B. Dick. In the early days, Hotpoint Appliances featured prominently in the company newsletter.
Most failures of this nature are due to the dishwasher drain dumping into it, very easy place to plumb it into for this purpose but the worst place for it also. Dishwasher soap is sodium hydroxide or lye if you know it by that name, very alkali and therefore very corrosive. It loves aluminum, which the disposal body is made from and eats it just as fast as it touches it. Move your dishwasher drain else where and the disposal will last a lot longer not forever though but longer. Always run the water through it for a few minutes to flush the grindings on down the road a ways. On a related note if your disposal gets smelly use ice cubes to grind it clean. Cram it full of them and turn it on and keep cramming them into it, rinse well. For your pipes sake run your hot water for about a half hour every now and again.
