Hello everyone,
our plumber didn’t want to install an exhaust duct from the guest bathroom leading outside, so it was installed behind the drywall with a special fitting. I was told it would be airtight because air could only flow in one direction.
Unfortunately, it still sometimes smells in the guest bathroom due to air pressure or something similar. I’m considering sealing the ventilation pipe completely, but what would happen then? Would it just cause gurgling noises when flushing, or is it better not to close the ventilation pipe?
Thanks in advance.

That is likely not an exhaust vent but the ventilation system. This can be done using a vent cap instead of routing it outside. However, it is necessary; otherwise, the water will not drain properly.
If necessary, check the ventilation valve to ensure it is functioning correctly.

Thank you for your reply. Yes, it will be the ventilation. Of course, it is behind the drywall partition, but I will install an access panel and check. Do I understand correctly that if the ventilation valve is working properly, there should be no unpleasant odor, or can it still occur?
