This might seem a bit weird to most people reading this, but drain vents don's seem to be used where I live (Spain). As you might expect, this seems to create a siphon effect in the drains - I think the water is sometimes being sucked out of the traps. Is there something like an anti-siphon valve that can be added neer the traps most affected?
The problem seems to be most pronounced around the toilet and especially after taking a shower.
