ᐅ Ikea siphon ventilation/drainage problem. It causes unpleasant odors.

Hello IKEA fans,
I’m usually a big IKEA user, but I’ve run into a problem with the Atlant siphon:

Under the kitchen sink, I wanted to create space for three separate bins for waste sorting, so I built the entire Atlant siphon system very compactly. However, when someone on a lower floor, for example, flushes the toilet or drains the shower, a vacuum pulls the water out of the siphon, causing bad odors to spread throughout the kitchen. It doesn’t happen all the time, but quite often. We live in a three-unit building, and we are on the ground floor and basement level. It could also be a neighbor above us who drains their bathtub, which “sucks dry” the siphon. The smell gets slightly better then but still somewhat unusual.

Maybe you have a tip? I understand IKEA no longer offers a service hotline like before. What did I do wrong? What do you think? I’d appreciate it if someone could share their expertise. Best regards, toll_dreist

Hello,

it seems the landlord solved the problem of poor ventilation at your expense. A trap does not need to be vented. If the trap is emptied because somewhere else is being "flushed" or "closed off," this is due to the wastewater pipe not being properly vented (the vent is usually located on the roof or on the upper side of an exterior wall). You had to vent separately because the building’s venting system was not working.

I suspect that the plumber and the landlord know each other, which is why the plumber did not tell you the truth.

Learn this: when you hire contractors for a rental property, always choose ones who are independent of the landlord.
