Garbage Disposal - On/Off switch
Comments (8)Thanks everyone - that's what i thought. My kids are actually well behaved in the kitchen as well. I have 2 little girls and b/c we have a galley that opens up into a dining area, they mostly stay in there anyway b/c I'm always yelling "get out of my space!" when I'm cooking or cleaning. And b/c our cabinets are old and hard to open, they tend to stay away from these as well. I just wanted to comfort my hubby. I think he's still traumatized by my 4 year old cutting her thumb on an open can and needing stitches (oddly he's a doctor and yet literally almost passed out watching her thumb bleed and yes, we've since got a can opener that doesn't leave sharp edges!). Thanks!...See Morepush button or electric disposal starter
Comments (1)Your GC is probably talking about an "air switch". It's a switch that sits on the counter that activates the garbage disposal (GD) by pushing it in once to start, and then again to stop. While it's usually used for GDs, it can be used for anything that is plugged in. The countertop button is connected to a plug under the counter by a tube. When the button is pushed, a puff of air toggles the power on/off. The GD is plugged into the air switch's plug. No, you probably don't need a new GD just to use an air switch, but if your GD is hardwired into your house's electrical system (i.e., it's not plugged into an outlet), then you will need to have it re-wired to add a plug. However, how old is your GD? If it's quite old, you might want to get a new one now. Today's GDs are more powerful, quieter, and can handle more "garbage" than they used to. This is especially true if you have a "Badger" GD...the builder-grade GDs that most builders install (InSinkErator makes them.) InSinkErator makes much better GDs in their Evolution line. Here's a picture of our air switch under the sink: Our GD is plugged into it. You can see the air switch on the counter to the right of our faucet: Here is a link that might be useful: InSinkErator Evolution Series...See MoreWhere is your garbage disposal switch?
Comments (21)Houzz convinced me to get an airswitch and they are apparently pretty uncommon, my electrician and plumber were both surprised to see one, @snappity - actually airswitches are now commonplace. They can be bought anywhere, in quite a lot of finishes, and I rarely see disposal wall switches in any kitchen renovations today. This thread is 12 years old, so even 12 years ago, the airswitch was commonly used. I like a batch feed disposal which has no switch at all. A couple comments on this thread mentioned them, but the batch feed disposal is truly less common....See MoreGarbage Disposal and Dish Washer off Switched outlet?
Comments (6)The bigger issue here is whether your existing circuit can handle the dishwasher alone, must less the disposer and dishwasher at the same time. And is there anything else (electrical outlets, lights, other appliances) already on the same circuit as well? Check first. What amperage is your circuit rated for? If it runs to a fusebox with Edison-type fuses (same size screw threads as a common light bulb), be sure it's of the original, intended amperage and not a larger one someone installed along the way. Modern electric code, as well as most manufacturers, specify separate circuits for the dishwasher and disposer. I've seen them frequently on the same circuit in older houses, and you may be fine if you only run the disposer when the dishwasher's not running. But dishwashers typically use about 1400 watts or 12 amps (mostly for the heating element, which both heats the water and dries the dishes at the end), and disposers draw about 8 amps. You'll need a 15 amp circuit to run them alone, and a 20 amp circuit for both run together (though since the disposer is run only briefly, it may not trip your 15A circuit breaker or fuse even if run simultaneously with the D/W). Devices permanently attached to electricity are not supposed to draw more than 80% of the circuit's maximum rated power, so a dishwasher that drew 14 amps would specify connection to a 20 amp circuit. Another issue - knob and tube wiring is inherently safe, perhaps more so than modern combined cables since the hot and neutral wires are run apart from each other, but it doesn't include a ground cable which your dishwasher and disposer should have. It seems possible, and easy, to add a ground wire to existing K&T installations but I don't know if this is allowed by code. Installing new knob and tube circuits is no longer allowed, but extending existing knob-and-tube wiring is specifically allowed by the National Electric Code. Many electricians don't seem to know this, and some, especially young ones who haven't worked on older homes, aren't familiar with K&T in general and are freaked out by the thought of electrical junctions made outside a metal box. Insinkerator sells a "cover control" disposer, as well as an inexpensive batch feed adapter that fits any of their Evolution disposers, as well as an air switch. The air switch seems like a good idea, but run this by someone in the Wiring forum here, or an electrician to make sure what you're doing is safe and at least relatively legal. The break-off-the-tabs solution, in and of itself, should work, but there are other issues here that should be considered....See Moreearthpal
