So apparently the trend is to NOT connect dishwasher drain lines to garbage disposals anymore, as the better garbage disposals have no connection?
So, in a single bowl sink where I have to attach a new garbage disposal, I presume I use one of those special drain tail pieces with the dishwasher connector on it? I’m guessing EL off the garbage disposal, attach to top of drain tail piece, which attaches to trap. Is that correct? Is there some place the dishwasher drain has to connect, vis-a-vis the trap and the garbage disposal? Is there any risk of water running back into the garbage disposal.
Course I gotta put a receptical in to replace the hardwired line, along with the dishwasher T…

Of the dozens of BadgerII, 1/2hp disposers I have installed in rental units, every one had a stub for a dishwasher discharge line connection.
However, as it left the factory, the inlet is plugged. The installer needs to remove this knock-out piece. A moderare rap with a hammer and cold chisel and it's out.
The one I like (used to be called a "Bone-Crusher" now has a new name) has no stub at all. And I noticed at the local appliance store (where I finally got a home theatre receiver) that all but one or two of the ones they sold (GE, I think) did not have a stub for a dishwasher drain). Only the very cheapest ones did.Well, like I said, the one I like does not.So, how do I connect the dishwasher drain on a single bowl sink with a garbage disposal that does not have a stub?
Use a T connector. Treat it like you were hooking up a double tub sink.
I missed the original post, but to hook up a dishwasher you should run the discharge hose through a air-gap fitting on top of your sink, then you run the discharge to a connection in the sink drain before the trap, I don't know if you plan to run it to code, but this covers most codes. If you are not trying to adhere to a code you can hook it up to the garbage disposer; [There are millions of them hooked up this way and they work fine]. Either way you will still need the air gap. Luck
Say what???
I've put in at least six disposals this year ranging from an el cheapo for a rental house up to the top of the line model in a very upscale house. Every one of them connects to the dishwasher drain line via an air gap on the sink deck.
I once (repeat, ONCE) put one in without removing the knockout. That little mistake showed up pretty quick when I tested the plumbing - lol.
The one I like is now the WasteKing 3/4HP Special Edition. Very quite and mostly stainless steel. Here is a link:http://www.plumbingworld.com/disposer.html#faqNo dishwasher connection. And most of the ones I'm seeing in Columbus don't have a connection.An air gap is probably the best choice, but I find them to be noisy and I don't like them, especially for this particular application as the kitchen and living room are one space. I believe there is an alternative involving creating a high point in the dishwasher drain line that is above the discharge point. But I've got to look that up.
You can get by with connecting the dish washer without a air gap, but this is a code violation, If you want to do it with a high loop its your call. {For years that was the way they were hooked up]. You don't have to look it up. Whatever floats your boat. Luck.
attach to top of drain tail piece, which attaches to trap
That would seem like the logical place. You would not want to drain through the disposal (or hang the disposal off the drain fittings).
I'm trying to recollect where it was that I actually saw a sink-mounted air gap. I want to say it may have been a HD Expo store.
Just goes to show how different places can be, I guess.
