Hello everyone,
As a non-professional in plumbing, I have a question whether anyone is familiar with this or knows a solution for the following problem.
I recently bought new bathroom furniture including a sink at a furniture store, and these items were delivered by their company. The in-house technicians installed everything, including the water connection for the sink. Unfortunately, the technician/installer had significant difficulties attaching the drain to the sink because he couldn’t properly fit the parts together and didn’t know how to do it – supposedly it’s a new type of drain.
Now, when the temperature rises, there is a bad smell coming from the sink drain. The sink has NO overflow, and as far as I can tell, there is no proper trap installed. (Previously, we had a different sink with a trap, and there were no issues with unpleasant odors.) You can also clearly hear noises coming from the pipe when a neighbor one floor above drains water from their sink and it rushes through the pipe.
I have the impression that the connection between the sink and the drain pipe inside the wall is not sealed by water (as in a trap), allowing noises from the pipe to travel through the connection pipe from the sink drain into the bathroom.
I’m attaching two pictures to at least illustrate the situation from the outside.
Can anyone tell me what is missing or what might have been installed incorrectly, if this can be determined from the pictures at all?
Thanks and best regards,
Gregor

EveundGerd5 Aug 2015 20:00This problem is well known to us. We had the same issues with the bathroom furniture in the shower room.
The plumber and heating technician involved in our house construction was very helpful.
He gave the decisive advice. The installers from the furniture store were clueless and didn't even try.
We custom-built the entire drain and cut out the lower drawer at that spot.
We had no other option.

Hello
The elongated horizontal component will serve as an overflow.
No trap is installed here.
For a surface-mounted trap beneath the walk-in washbasin, the height difference of the connections will not be sufficient.
I would solve this with a PVC trap in 1 1/4" x 40 mm (1 1/2 inches x 1 5/8 inches) and a space-saving bend.

Hello again,
Yes, a drawer with a cutout would also work. However, it will likely cost time, money, and space, if there is even enough room available.
Since I don’t really know the gap between the drawer and the wall, with reservations:
Use a 40 mm (1.5 inch) HT elbow pipe at 87° to the left or right,
install a 1 1/4" x 40 mm (1.5 inch) PVC trap between the wall and the drawer,
and connect the drain to the trap using a space-saving 1 1/4" elbow.
Done.
