Is a siphon necessary in a paved garage?

Hello everyone,

Is a siphon necessary in a paved garage? The water can also seep through the joints. And with a siphon in the middle of the garage, a slope has to be made from every side to the siphon, and without a siphon, paving would be simpler, as a slope towards the garage door would be sufficient (the area in front of the garage is also sloping). Thank you very much

Hello,
as far as I know, you are not allowed to have a drain in the garage at all. Otherwise, in the event of an oil leak, the oil would uncontrollably enter the sewer system.
Which water do you want to let infiltrate? The water that you bring into the garage with the car when it rains?
Otherwise, it probably also depends on your ground and your paving.

By the way, we solved it like this: The screed in the garage has a slight slope towards the garage door. If there should ever be larger amounts of water (which has not been the case so far), it can then run off towards the door. In front of the door, we then have a channel.

Do you mean a drain because a siphon has the function of reducing odors!

Yes, I mean a process with a siphon. Water/snow that comes into the garage with the car A wastewater pipe comes from a sink in the garage. And on this wastewater pipe, a drain could be made in the middle of the garage. I wonder what that would really achieve

Then relax.

Ensure ventilation in the garage (e.g., windows) and, for safety, make sure your pavement has a slight slope towards the garage door.
