CL: Looks like a p-trap for zero-gravity zones. Maybe a lazy-p-trap.

[Gunnar Alquist]

That would be one of those new style b-traps (or d-trap, depending on which side you look at it).

[Bruce Ramsey]

Trombone trap

[John Kogel]

Not a trap, not an elbow. It's a C-bow.

That's one of those designer glass sinks that has built-in overflow. It just overflows over the sides of the bowl! :)

[Michael Gregory]

Just goes to show you can't make anything foolproof, the idiots are far to creative.

[Markus Keller]

Sorry I can't comment on the trap, my brain is still trying to recover from the wallpaper.

[Jon Errickson]

I don't know, when you're laying on your back under that sink and dizzy from looking at that wallpaper, it kinda looks like a P-trap.:D

One more question, Is this no-overflow-channel sink allowed? How can we report for home inspection.

[Michael Thomas]

"Sidely Whiplash".

Does the code require overflow channels in sinks? I was recently looking at the study materials for a plumbing license and it didn't mention one and several sinks I've seen don't have them. Could it be a local requirement?

In the sinks I have seen with them they are usually bacteria and mold culture labs. I can't think of a better place to grow mold than a dark, warm, consistently moist cavity like an overflow channel.

I have to say, given the choice between a non-trap like this and the fancy bottle traps they usually sell with these basins, I'd rather the DIY crowd used the bottle trap.

No requirement to have an overflow.

That's why the BC Building Code 2006 does not allow a "Concealed Overflows" for dishwashing and a food preparation.
7.2.2.4.1) A dishwashing sink and a food preparation sink shall not have concealed overflows.
That means an open-channel overflow is allowed.

No requirement to have an overflow.

I do tell clients with small children to either remove the stoppers or monitor the children in the bathrooms... A kid who fills the basin while brushing his teeth can get distracted pretty easy... :-)

Especially dangerous in those upstairs bathrooms...

[Jack Feldmann]

Kitchen sinks don't have overflows.
Laundry wash sinks don't have overflows.

No requirement to have an overflow.


Not only no requirement for overflows in sinks but I have not seen a sink with an overflow which could keep up with a full water flow ... meaning the overflow is basically useless ... I say "basically useless" recognizing that if one were to put too much water in the bowl, have the water off, and then put your hands into the water, the water level will rise and the overflow would likely handle that.

Not only no requirement for overflows in sinks but I have not seen a sink with an overflow which could keep up with a full water flow ... meaning the overflow is basically useless ... Nevertheless, an overflow will help and if the taps are not on full, there will be minimal or no water spillage.
A typical double kitchen sink has built-in overflow protection, the other side.
It takes a lot of water to overfill a laundry tub.
By coincidence, I had a glass bowl sink this PM. Turned the water on full with the stopper down, and had a 3/4 full sink in less than a minute. That is too short of a safety margin in my mind. Ok, I don't like these sinks.

I've seen the bottle traps used on pedistal sinks, but not on anything else.

[Randy Aldering]

It looks like an improperly installed trap.

I have long suspected these overflow channels were a bad joke created by the plumbing industry in collaboration with drain openner manufacturers.

[David Bell]

Looks like a BOOBY trap,,just can't stop lookin at it.

I'd label it "wrong".

[Steven Saville]

Homeowner is probably wondering why he has constant problem of sewer odor in room. (Hope he has a good exhaust fan!)
Obviously does not know the purpose of traps.

[Michael Thomas]

There double trapped, and then there's double trapped. Both from this afternoon's job:

It was a bear of an inspection - 143 pictures of the usual &()%^#%$ REO stuff - but nothing else quite came up to the level of the "trombone trap" or the forming technique for that pier, probably the next best was the collapsing service mast that brought the service drop down onto the roof:
