Hi All,
I am helping a friend replace the p trap in the hair washing sinks in her salon. The old traps are rusted and beginning to leak.
She has the European style traps to replace them with that have an internal plastic tube to form the trap so it appears it meets code as it does not use moving parts to prevent gas flowing through and it uses a plastic that will not deteriorate like a metal tube allowing gas through.

In any event, the trap comes with a flanged 1-1/4" tail piece to go from the sink to the trap. The existing setup uses a threaded extension that goes from 1-1/2" to 1-1/4". I have not been able to find any pipe that has a flange end and drops the size from 1-1/2" to 1-1/4". The existing extension goes directly to the drain with a threaded collar going up into the drain holding it in rather than a threaded pipe end with a collar holding it from above.
Is there somewhere I can buy an extension with a flanged end rather than threaded?

My other question is for the drain pipe as it enters the wall. The existing pipe from the trap is slip fitted inside the pipe going into the wall and appears to be sweat soldered together. What is the best way make this connection with new pipe from the trap? I can heat up and remove the existing pipe but is soldering the new chrome pipe into the old drain pipe the best way to go now?

Thanks.

Is the drain concealed inside a cabinet ? If so, then there are many transitional fittings you can use for that purpose. And if you start running out of options, there is always Fernco with fittings of just about any configuration you need.

If you post a clear photo of your situation, I will tell you exactly what to get

I do not see a way to post images here and I do not currently have any place to host pictures to add a link.
I did manage to find the extension I needed searching for flange reducing tailpiece.
The remaining question is about what to do with the drain pipe.
The drain pipe exiting the trap is slip fit inside of the pipe coming out of the wall and soldered in rather than using any type of compression fitting.
The pipe coming out of the wall extends about 2" and appears to have been expanded with a pipe expander to be large enough for the drain from the trap to slip right inside it so unless I am to solder the new pipe back into the old wall drain the old pipe is too large for typical fittings. I hope not to have to replace that connection to the drain to make standard connections work but the area under the sink is fully exposed and in a hair salon where it needs to look good.

Searching a bit more I believe it is probably a solder bushing that threads into the drain pipe in the wall with an extension through the wall to solder into. I may be able to remove it and put in a new connection with a more modern way of connecting the sink drain. I can open the wall on the other side to remove the old fitting, I just need to confirm this is the actual situation and determine what to replace it with.

Now that I found the advanced menu I can post images.

One image shows the extension from the sink using a flanged pipe rather than threaded but I did find a reducing flanged tailpiece to replace it with.
The other shows the soldered connection into the drain pipe in the wall.

Thank you for the visuals...

The pipe coming out of the sink appears to be threaded onto the sink drain. If that is European configuration drain / sink combo and such tail piece cannot be found, then just cut it off 3" bellow the nut, get regular extension piece and connect to it.

However, we do use "Branch T" that has very similar, if not the same, type of connection.

If everything fails, go to rubber Fernco coupling that will fit that size. You can even remove that existing tail piece from the sink and attach Fernco coupling directly over the threads.

The pipe coming out from the wall: Just cut of the chrome piece where it enters the drain pipe and use Fernco fitting. No soldering there.

Fernco fittings come in just about every configuration there is. Just pick the right size. Some are all rubber with 2 s.s. bands, some are shielded. I suggest you use the all rubber once as they have a bit of play.

Hope that helps

I think those Fernco couplings will be the perfect answer as it will still sit close to the wall and the escucheonon plate is a deep dome that should cover it well.

The European bottle trap is a much cleaner look for the exposed plumbing especially in a business like this salon. I had to do a lot of reading in which it was strongly indicated that they were not code compliant in the U.S. but when I read the actual code it appears they are and that either earlier versions were not compliant or there was confusion over the types of bottle traps that were once used in showers.
I have yet to find anyone who states that they are legal but all of the discussion threads I have seen have been quite dated.
