plumbing like vents

If you do not have a plumbing roof vent here is a low cost way to solve it.     You would do this at every sink location in your house.  

mind you these generally fit the typical plastic found.used in the USA, your plumber will have to cheat a bit but it is not critical  have them use silicone as this is not a pressure fitting.  

these can be bought at true value
