Sink Drain - Why holes in sides?
 

I just installed a sink drain.

The drain has two retangular holes (about 1" by 1") in it just below
the top surface
of the sink and above the underside surface of the sink (above the
undersink gasket)

What are the purpose of these holes? Seems like they just provide a
cavity between
the outersurface of the drain and the inner surface of the hole in the
sink where the
drain fits. Drain water must accumulate in this cavity, I would think?

There should be an "overflow" slot in the sink up near the top edge.
The water that goes through the overflow has to be able to get into the drain
pipe, even if you have the plug in the basin, so it comes in the sides.

That would be the over flow. Some sinks have them some do not. Your
drain (actually the part called the tailstock) should have rectangular
holes in it just below the stopper to allow the water that runs into
the overflow to drain out.

Thanks, this sink does not have an overflow slot, so they serve no
purpose on
it. I guess any water that gets into these holes (gets caught in the
cavity) will have to just evaporate out. This is a guest bathroom
sink that
is not used often

I could try filling the cavity, but I would have to take the plug
assembly out
again.

Well it sounds like you have a sink with an overflow that has a
tailstock that has no provision for that. So whoever put it in that way
made a mistake. If it's not used very often it's probably not a
problem. It would take water trapped in there a long time to evaporate.
I have kids and this would definately be a problem.

You won't see my reply, but.

Did you use plumber's putty around the top of the drain and the nut
tightened enough?

Probably the place where you hook up a dishwasher. Sounds like the
wrong tailpiece

But seems that would be a vent hole, not holes.... IDK, but something
ain't right.

Mike, I'm faced with the same thing. I have a custom sink bowl (no overflow)
and the water is running out through that slot in the drain pipe. From what I
have read on this site, some come with the slot and some don't. You need to
replace the drain pipe with one that does not have that extra slot/hole for
the overflow. I wish I had known this before. Practice, practice,
practice..... Thanks for everyone's posts.

I did have a small defect under the bowl where drain pipe gets tight. That's
where it was leaking. I looked at my other sinks they are bigger underneath
and overflow drains into those pipes. I will look for new drain pipes without
holes on sides. Other people had problems with this same vanity sink combo.
They used putty and silicone.

Wow are you folks at HomeMoaners having all kinds of trouble. The OP
had a new drain with holes, now you have a faucet with holes and a
new sink that doesn't have a drain hole. Wow, are you all smoking
the same stuff?



I had leaking and everything was tight.
I did have a small defect under the bowl where drain pipe gets tight. That's

and overflow drains into those pipes.

Every sink I've had, the overflow was integrated into the sink and there
was only the one drain connection at the bottom. Other types might exist,
but so far it seems HomeMoaners are the only folks finding them, buying
drain pipes with "holes on the sides", etc.

Probably a good idea.

Pros use plumbers putty, hacks use silicone.

Every slow draining sink I've seen, the problem was never the sink, it
was a clogged drain, incorrect plumbing, etc. The sink just has a
standard size hole in the bottom, now can it be the cause of slow
draining?
in the bottom

A vessel sink vs a standard sink use differnt tail pipe drains. A
vessel sink doesn't have an overflow. HomeMoaner may have bought the
wrong part? No, not possible.

IDK, but if you have a sink that has just one drain hole, like most
and you're buying a drain assembly, you would think if the pipe had extra
holes you'd figure out WTF was going on before buying it and
putting it in. But, heh, that's just the way I do things.

I suspect many of the posts there are just fake spam, designed to try
to build traffic for the website. It's hard to believe people could
be that dumb. Also, if you notice, most times it's a one hit wonder.
They ask some inane question and are then never heard from again.

Those two holes in a sink are called drain holes. And those drain holes are used for water overflow in a sink.
