In the Mouth of Your Disposal...

Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

Help Support :

At home I’ve got two old WasteKings, a 1989 and a 1969. The newer one is a Thermador branded one! I call it “all roads lead to the King”.

And I dropped my brand new iPhone in the sink, right under the faucet! Thankful for water resistant iPhones!
 
When my drain plumbing was replaced a few months ago the plumbers put in a Moen half Hp disposer-Its a tough little thing shreds banana peels without any problems.Sounds like you may have stopped the WP disposer before it was done shredding-hope it doesn't get jammed.
 
I looked in the WP, it had a couple small bit of bone rolling around, I’ve noticed most tend to struggle with those smaller bits of hard material, I usually just let it deal with it over the next few uses. And yes, if you leave much of anything in there, it can easily jam up on that fixed impeller, then you have to reach in while it’s off and rotate the turntable backwards a little bit and it’ll usually start right up. But I do try and avoid that happening!

The Moen disposer is built like the WK on the left side of this sink, but the slightly smaller unit. I’ll be honest and say it probably performs just like the 1HP one in the video, even on larger and more challenging items like bones and rinds. I’ve also found the vintage style WK machines, the older 1/2 HP unit does just as well as the newer 3/4.
 
Moen does have a 1 hp disposer-like the WK models-we can safely say these are all built by Aneheim Engineering-but in China.They are good machines despite that-they shred well and fast!The PM motor has more torque for its size than an induction one-no start windings or switches to cause the motor to stall or overheat-the rotor in the DC PM ones can overheat-but in disposer duty they are fine.The stators of the PM DC motors are perm magnets.

Hi Reggie thanks for posting, that is a fun demonstration.

 

We had a WP disposer like yours in our house from 1972-1976, then I put in the upgraded WP batch-feed sound insulated version of the one you have with Auto-Reverse, it would only reverse if it jammed while trying to start or if it jammed while operating which did not happen often. I kept this WP till 1994 when I installed a custom made Maytag FB-5 [ MT never made an FB-5, to get one I had to combine a FB-10 with the shorted FC-5, I needed a shorter disposer to fit our plumbing ]

 

Your demonstration was cool, those little permanent magnet motor disposers are fun but I just don't like the durability of them to say nothing of the plastic sink flange. They also do not grind the waste as finely or uniformly as the WP does.

 

I have in our collection a lot of cool older disposers you would probably love.

 

Here is a lot of disposers and appliance motors I loaded on the truck for recycling two weeks ago, see if you can identify them all, LOL  As you can see they are almost all mid level to basic ISEs.

 

We change out many disposers every week as disposers are required here in DC.

Looks like mostly ISE badgers, YUCK! I do like the better ISE models though, a friend of mine has the TOL Evolution Excel, it is sort of the the modern version of the good old Waste King Universal.
 
I think almost all modern disposers could use smaller holes and undercutters. Not many disposals can do what the old Waste Kings can!
