What type of sink trap is this? PIC.

Give the poor guy a break. He needed to drop the trap so he could install the tail piece for the dishwasher. Of course, when the dishwasher empties, it'll be hitting a pipe already full of water. Eventually the pipe will fill up with water to the point it can go downhill.

These traps are everywhere in Europe,I have a house in Cyprus I have two of them,one in w/c and kitchen and I have never had any problems.Works just fine!!!

I just love it when a homeowner tells me this

I'm sure you can appreciate the humor I derive from those statements.

Actually DRUM trap and BOTTLE trap are different. The one shown in the picture is a bottle trap. They both are not permitted in Canada. The static water level is below the outlet and sewer gases may escape from outlet to inlet.

I thought this message board was made available so we as home inspectors can learn from each other.I guess I was wrong!!

The picture of the" bottle trap" was actually taken by me,I asked that Nick or Deanna post it because I for some reason was unable.I took this photo of my hotel room vanity it had two wash basins,they each had a bottle trap.
The hotel's name is RIU PALACE it is a five star hotel that is 2-3 years old. It is owned by a Spanish company.The hotel is in Los Cabos, Mexico.

Jeffry and Roy maybe you guys know better about these things than the Mechanical Engineers???

P.s. Have you guys even used a sink with one of the bottle traps,or have you even seen one?

You are right not legal here,I asked a building inspector Friend and they say that they turn a blind eye to them.Reason,when they leave after final inspection homeowners will switch them anyway.Usually are installed in high end homes.

I certainly would not go as far to say that.

There is a reason why these are not allowed in the States. I don't profess to know that reason, all I know is that there are specific requirements for traps, which bottle and drum traps do not meet.

[Mario A. Kyriacou, CHI]

I hate to burst your bubble Jeff but the U.S. or Canada do not hold the monopoly on mechanical design.I know they are not permitted in the U.S. or Canada.
You have to be a little bit open minded.

Burst my bubble? I said "I don't know why." Where's the bubble?

I'm sorry if you took offense to my reply to your statement, but I hear this from homeowners all too often.

Just because you have not noticed any problems, certainly doesn't mean that problems don't exist.

It may be that these work "just fine." I don't know the answer to that either. All I do know is that they are not allowed in my jurisdiction, nor is the flexible tail piece. But both items can be purchased from many local hardware stores.

When the model codes accept them, I will follow. How's that for "open-minded?"

This statement is not open minded.

Bottle traps are used in many parts of the world but are not allowed in the US model codes. The reason why is because they rely on partitions that are hidden inside the trap for their seal. If (when) the partition corrodes away, the trap seal will fail and allow sewer gases to enter the home. Because the internal partitions cannot be seen without taking the trap apart, and it could still look ok to the average person while having failed, the homeowner could think it is still doing its job of keeping the sewer gases out of the home when in fact it is not. They are found a lot on "high-end" homes because they look a lot prettier than a standard trap when you have the under-sink plumbing exposed. Will they work ok? Yes, for a while, but the average homeowner will not know when they are not working ok.

Now THAT'S educating.

I try not to limit my suggestions to "it isn't allowed" or "it doesn't work"--
but this I can, and will use. I always try to inform why it isn't allowed or doesn't work.

Thank you ever so kindly Mr Chew, Sir!

Partitions are now PVC pipe as far as seals are concerned I don't know.
They do look cool don't they?
