Most of the one's I have run across do not have an overflow. Mainly used for disposal, dumping out drinks, etc, not for washing so overflow not really an issue. Also, most are stainless which do not lend themselves to an overflow drain.

Why are there holes in the side of the drain pipe of a sink?
They are there so that the water that flows out the overflow skupper runs down and into the drain. When the drain pipe is mounted they end up sealed into the area between the inner and outer bowls of the sink.
Is an overflow drain for a tub and the clean out drain for tub the same?
Usually. Going through the overflow drain gets you straight into the drain without having to make the sharp bend in the tub drain. There could be a trap that comes apart in the drain underneath if it is accessible.
Why does your garbage disposal back into the dishwasher?
The sink drain is blocked somewhere after the disposal. take apart and clean or renew sink drain.
Can you connect sink waste vertically into horizontal pipe that exits rear of toilet at side of proposed new sink location.?
You can, I'm not sure that I would. Probably doesn't pass code for one thing. If that is not an issue, that is the main stack. Down to the sewer, up to the roof vent. If you attach a sink drain there, when the toilet is flushed, it will pull venting from wherever it can. Most will still come down from the roof, but being as close as it is, it will also pull from the sink drain and cause a gurgling from the sink. The other consideration is the sink itself. Make sure it has an overflow vent in the rim of the sink. If the one you use doesn't the drain will need a vent of its own, otherwise the sink drain will be trying to pull against a vacuum. Another thought. They make what is called a Saddle Clamp to do what you are talking about. A half piece of pipe with a female connection in the side of it. Made of PVC and held on with two clamps that go around the existing pipe.

How do you install overflow drain in non over-flow sink?
The overflow is built into the sink, it is not part of the drain. If there is no overflow, you can not add it.
Is the sink overflow made to prevent the sink from overflowing even if the drain stopper is down and the water if fully on?
In my experience, I would say no. Several reasons can prevent the overflow from working. Since the overflow of the sink is rarely used it has a tendency to be blocked at the lower portion where the sink joins the drain pipe. During normal use and over years the holes in the sink drain at the point where the overflow and drain pipe meets has a tendency to clog making the overflow drain slowly. You can notice this when your sink drains with a "gulping" sound. You can test the overflow drain and see how obstructed it is, but do it slowly and do not turn on the faucets on full.
Can you use a lavatory drain designed for sinks with overflow holes if your sink does not have overflow holes?
Yes, they work in either.
What is the stink coming up from the overflow drain in bathroom sink?
If you have a stink coming up from the overflow drain in your bathroom sink, you have some garbage down there that you should not have. You probably have a lot of hair clogging the drain. It is probably slow draining. You need to clean it out and get rid of the gunk.

How Trap and the trap should be vented?
The trap and drain in most sinks gets it's venting from the overflow tube in the sink or in the case of a double kitchen sink, one side gets it from the other. One problem is with most cultured marble and cast sinks. Most of these do not have an overflow feature and may drain slow.
What should be done when running the garbage disposal causes backup and overflow in the tub and bathroom sink?
Have a plumber snake out the drain. You have some sort of blockage.
Why are there holes in the drainpipe of the sink?
Sink drains have holes on the sides to mate with the overflow drain above the drain flange. While most water goes down the top, some may overflow and go behind and though a channel in the wall of the sink. Then that water goes through one of the holes on the side of the drain and goes down. When you are installing it, you should try to align the holes with the overflow channel. You might have to compensate for rotation as you tighten the flange. In other words, you might want to partially block it to where any rotation will cause the pipe to rotate into the correct position. This can be inconvenient when you are attaching the drain kit to a sink that has no overflow holes. In that case, the holes in the pipe serve no purpose, and you have to make sure things are sealed well so it won't leak between the rubber flange and the holes on the side. There may also be a single, threaded hole further down. That is for the lever for the popup valve for the drain. The lever pushes the drain plug up and/or pulls it down.
Why does the shower overflow when I use the bathroom sink?
You have a partial blockage downstream of where the shower drain & the sink drain join into one pipe. You could try a thin plumber's snake, or add some drain cleaner, some bleach, or vinegar. About a liter of vinegar is the safest and should work well enough. Davis (davisbigelow.blogspot.com)

Can the Tub Overflow drain leak?
Yes, the gasket between the overflow pipe and the tub can go bad, or it can leak around where the pipe is attached to the drain.
