Hi,

I have a copper sink in the bathroom and because it doesn't have an
overflow, the water drains very slowly. It is not too much of a problem,
because as the sink begins to fill, it drains more quickly due to
gravity, but as it drains down, the rate slows down dramatically.

But my kitchen sink (as most kitchen sinks) also doesn't have an
overflow, but doesn't have the same problem. How come? Is it because
kitchen sinks have a larger drain?

Thanks!

Hi,
Today no sink has overflow(I think it is against code) You better make
sure your plumbing vent stack is in good working order(no obstruction).

I think it's against code to *not* have an overflow.

My kitchen sink is going to jail!

Hi,

Today no sink has overflow (I think it is against code) ...

Most, but not all, bathroom sinks still come with an overflow port. At
least that's how it is here in the U.S. An easy way to check this is to
look for bathroom sinks on Home Depot and Lowes websites and look at the
"Specifications" for each sink.

I don't know of any code that prohibits overflow ports in sinks, and I can't
think of any reason why any such code would be written.

Yes they do. I just bought a Kohler and it and every one in the store had an
overflow somewhere, usually hard to see until you look close. Not sure what
you're thinkng of, but it's not an overflow for the sink.
Besides, the problem here isn't the lack or presence of a sink overflow:
Normally they just feed into the drain below the stopped level. There is
supposed to be a vent stack for it somewhere, possibly buried in a wall or
sticking out the roof or both. No, I'm not talking about air traps to stop
banging.

I think it's against code to *not* have an overflow.

I concur.

Where is the overflow on vessel sinks?

In the drain tail pipe....

Then it's hardly an "overflow", no?

but it you close the drain.. then what?

The sink overflows. ;-)

Some vessel sinks can have an overflow tail pipe drain.. not mine.
They are made...

My point was that an overflow can hardly be a code requirement.

but it you close the drain.. then what?

I haven't been able to find anything definitive on that, either. A
couple of websites wherein someone claimed that it used to be code but
isn't any longer, or that it's still code but no one enforces it
anymore, partly due to the proliferation of non-compliant vessel sinks.

I did hear many years back something about it being required, but
apparently I'm either wrong, or, as my friend who is never wrong once
declared "I wasn't wrong, I was just informed with old information."

I hope we can all at least agree that it couldn't possibly be "against
code" to have an overflow as Tony opined.

As far as HeyBub's non-compliant kitchen sink, I assume that it's either
a double with a spillover bar, or that whatever guidelines used to be in
place automatically assumed such a sink in the kitchen.

One thing I hadn't noticed about our little group prior to this issue is
that although we have several NEC junkies, we apparently don't have any
UPC junkies.
