Question: does this have an air switch?
Document: I have installed two of these disposals for customers and they love them. They are the best for island sink were no switch is required.
This was part of a kitchen renovation. We have been happy with this disposal. It only operates with the drain cover securely covering the drain/disposal. There is no risk for fingers to get caught. It is quiet, powerful and no difficulty correctly positioning the cover to activate the switch after the first try.
Because the WasteKing has a mechanical switch this is not an issue.Aesthetics:The ISE certainly looks prettier but unless you have an open cupboard that's, frankly, a little too precious a reason for choosing something as bonegrindingly utilitarian as a garbage disposal--and it will dispose of bone without fuss.
The problem then is when you insert the stopper into the drain and then push it down over the switch the disposer is then sealed and no water can get in to help flush the macerated waste away. Reaching my hand down into the sink instead of a flicking switch to operate the thing is awkward & unfamiliar and will take some time to get accustomed to.
I have been happy with this disposal. It is very safe since it is only operates with the drain cover securely covering the throat of the disposal. There is no risk for fingers to get caught unawares or for shards of food (such as bones) to unexpectently fly out. It is quiet, powerful and I have not had difficulty correctly positioning the cover to activate the switch.
The inside of the plastic plug gets a little funky at times because the ground food scraps splash up into it, but give it a quick scrub with an brush and it's fine. With the kitchen remodel, I had the disposal hooked up to switch anyways in case I ever wanted to convert back to a traditional continuous disposal.
This is a top notch food waste disposal. No problems over the past few months with heavy use. The 1HP was the way to go. Dont go less. If I had to mention con it would be the alignment of the plunger with the switch. It seems to confuse many of the people that use it (I have this in a high end beach rental). You have to align a small notch. Not easy.
I bought this disposer because a LEADING Consumer magazine rated it # 1 for 2012. The disposer is Extremely QUIET, is good @ Grinding, has a Nice Price, and can be wired to operate without a wall mounted on/off switch. I had the disposer installed so I can't attest to the ease of installation. The &#34;Batch&#34; feed will take a good while to get used to however.
)Mechanics:The switching mechanism is mechanical as opposed to the ISE's elegant magnetic switch. I'm not sure which one will prove more reliable but I would bet the WasteKing will outlast the ISE. Lining the drain plug up takes at least 27 seconds of practice but you'll figure it out.Cast-Iron Sinks:Another advantage of the WasteKing is it's functionality in cast-iron sinks.
However I can live with that.I had read much earlier that one person thought that it was difficult to get the drain cover/switch in the proper position to properly operated it. I find this to be no problem. In fact I like it much better than the KitchenAid/Insinkerator batch drain cover/switches that I have been using for more than 40 years. In all my previous homes I have had either KitchenAid or Insinkerator disposers.
Answer: yes
