Evolution 200 waste disposer

Is now residing under my sink and can I say what a wonderfully quiet well engineered piece of equipment it is?

I had a Turkey carcass in the freezer and its bones are now history and so quickly and quietly its amazing I will never again have a cheap model installed its worth paying the extra.....

that makes it sound like you'd rather have a rotted turkey in your backyard. one the point is to not have that and two you kinda made it look like you compost turkey..... which we all know is forbidden in compost. (this was a reply to a comment further up the thread.) then plumbing thing's about how few places do it. now knowing the difference it makes i'd do it.
 
I had been noticing my disposer was leaving a small ring of waste at the bottom on a regular basis. Ran for longer periods of time with water and sometimes dish detergent to get it all out. It was bugging me why this started recently. Was thinking about what the problem was and if it was time for a new disposal. Then I thought this is not a batch feed disposal this is a continuous feed. I was loading it all in and then turning it on. WRONG. Started turning it on then feeding it. Results are no more waste ring around the bottom and clean every time. Sometimes we are the creators of our own problems. lol.

Disposers...again

My current home is the first one that's had a disposer, and we don't use it because our line is cracked under the slab and using the disposer seems to clog it up more often. So, I basically don't use it.

I hadn't planned one for the country house because I thought it would be bad for the septic system.

So, disposers and septic systems. What's the verdict?

Thanks,
Sarah
 
This is the first place I've lived that had a garbage disposer.

It's also the first place where I've encountered clogged kitchen drain pipes.

The clogs seem to happen at a hinky spot where the kitchen drain line intersects with a laundry closet drain, a shower drain, and a bathtub drain line before it reaches the main line. Usually the water backs up into the shower stall.

I had been running lots of orange peels through the disposer, until the last clog event flooded the bath and the wood hallway just outside it. I have since sharply curtailed disposer usage, and run only a few sections of orange peels through the disposer. Also got a flood alarm that sits in the shower stall (it is rarely used) to alert of the next clog/flood.

I recognize the problem is with the drain line connection between the old 1941 shower stall and tub, which takes a weird sort of turn. But until I can get that addressed the disposer will see much less food waste.

And yes, grease is very bad for drains. I try to drain that into the trash before washing a fry pan, etc.
 
I had a problem yesterday with my disposal. It was vibrating like crazy when running. Looked in and the moveable "blades" were locked in position inwards and sideways throwing it off balance. Had to take penetrating oil and drip onto the slots then 3-1 oil to loosen them up so that they would turn and swivel. It looked like rust underneath them. This is a n-sink-erater all stainless steel. Got one of them free completely and the other won't move completely in its track. It is a lot more balanced and doesn't vibrate as much. Never had this with all the disposers in different houses I have lived. This is probably why I had an issue last week with it not grinding all that well and leaving waste at the bottom. Question is where did the rust come from?

Stuck Blades In A Disposer

Hi Jon, This usually results from not using the disposer regularly to grind heavy loads of waste that contains things like fruit rinds, bones, peach and cherry pits etc to keep things free.

 

Grease should not go down any drain of course, I recycle grease by saving it in old quart jars and then take it to restaurants where they will let you poor it into their grease collection system. 

 

Used household grease is a valuable resource that should not be discarded, small quantities can also be burned in places like outdoor fire pits.

Thanks John I will start putting more solid waste down. Will start with chicken bones to start the process. Have been putting potato peelings and orange skins down but I guess that has not been enough.

I have seen a few with Sharp blades from the 50s and 60s models. They don't really help though. They normally use them as a center ripper blade. You know when you put in a orange and it rolls around forever.The ripper blades do speed up the process drastically.
Here are some of the best disposers.
Pic one is a G.E. disposal induction motor with the Carboloy cutter.
Pic two is a 1985 Waste King SS5000
Pic 3 is a 1969 ISE 77 disposer.
They all grind great but, the best one I think, would be the G.E. all food has to go through the small holes in the shredder ring and they don't wear. With that Carboloy cutter which is that small square spike down at the left of the pic that you can barley see.
Carboloy is a alloy of tungsten and cobalt.I had a 30 year old used G.E. disposer and that cutter still had a edge to it. I tested it against a unused G.E. disposer and they both ground the same. I guess that is why G.E. stopped making it.
They were expensive and worked to good.

Besides disposers-Carboloy cutters used in other things-large shrwedders-and Tree-brush mulcher shredders mounted on Skid Steers.Feel the Carboloy shrdders should COME BACK in disposers!!!Also some GE Hi speed disposers with the universal motors had the Carboloy shredder.VERY effective!!!Carboloy started out as a cutting edge for machine tools-lathe cutters and cutter element for large milling cutters.Now used today in large wood planers!Makes nice cuts-quiet-you could talk to someone nearby while planing a board.Not so with conventional planer blades.And on these as one edge dulls-just rotate the cutter 90 degrees for a fresh sharp edge-you can do this 4 times total before the blades have to be replaced.Same with the mill cutters.
 
Great Pictures Wes

These were all great disposers, I think from my experience the GE was one of the longest lived of the 3 you posted,

 

The ISE with the fixed impellers would be the fastest grinding, but more prone to jamming [ which is way it reverses every time it starts.

 

And these earlier WKs were great all around performers.

 

I think all commercial disposers still have fixed impellers for fast grinding and durability.

That is one thing that really supersized me John.I have another 1976 ISE 77 thats at my Dads place. It has that fixed ISE grind system on it and its jammed maybe twice but that is it in 15 years. It was new when I put it in in 2007 or so.
I love the fixed hammers they will smash anything very fast. The old Kitchen-aids while better disposers because of under-cutters on it tend to want to bounce things around forever.The old ISE would be perfect if it had undercutting on it.

I have been using a Old 1976 Sink-Master disposer with a induction motor and it does really well for a cheap disposer.I guess it was kinda expensive in 1976 at 90 bucks.
Sinkmaster/Whirlaway has let themselves go really bad ever sense they changed there name to Waste-king.
I found a commercial Bus Boy disposer that I bought brand new I am going to install it here in a few weeks...
The 2 pic in the Busboy commercial I got.
The 3 is the 1976 SinkMaster ..
The 4th is a 2010 Whirlaway it is crap, look at the gap between the flywheel and the grind ring. They have to take huge chunks out of the flywheel to balance it.
That Busboy is smooth has silk and quite for such a large machine.

Choices, choices

ISE Evolution XTR vs ISE Septic Assist

The septic assist has a solution called bio-charge that's supposed to break down fats, grease, protein and starches. I've always been taught that fats and grease just shouldn't go down the drain, so is this a valuable feature?

Also, with a septic tank and room to compost, does it make more sense to compost than use the disposer? It seems to make sense that using a disposer could promote the growth of the biologicals in the septic tank, but will it increase the frequency of needed cleanouts?

And wouldn't grinding a chicken or turkey carcass introduce too much fat into system?

John, you mentioned putting the absorbent mats that come with meat down the disposal. That seems like it would be a definite no in a septic system. Thoughts?

Many thanks,
Sarah
 
ah yes old 50s GEs
and my arch nemi- that word that doesn't exist in my vocabulary.
the old 70's/80's WK ss5000 The HUSH i would die to own a new one of.
what i thought would just be... flipper blades (like the waste king and the ge) but none of them stand up very far (the old insinkerator and that old whirlpool are examples of this and most)
do you have any idea where the whole "sharp blender" thing came from? were any of those 50's ones even remotely similar to that, or were they pretty tame like the waste king?
 
blades
this is the inside of the Maxmatic/wastematic/tweeny whatever name
it's all cast. i know you've said that it's made better when cast that's why i said it over ise
