Basement: Laundry room / Shaft still up to date?

Whether or not an Aquastop is installed on the washing machine doesn’t help much if something in the machine is leaking or a water pipe becomes leaky. Therefore, I also think there should be a way to easily get the water out of the basement. And a pump sump is already an advantage in that regard.

I don’t quite understand how the individual heights work for you. You write that the city’s wastewater sewer is higher than the basement. What do you mean by that? Higher than the basement floor, quite possible, or is the house situated in a depression? As I said, there are a few things I don’t fully understand at the moment.

So, just wrote that down like that. How about running the wastewater pipe from this pump sump up into the kitchen or bathroom and then connecting it to the sewer there? That way you would get above the backwater level, and it wouldn’t be so expensive. However, you would, of course, have to hide it visually.

The basement floor is below the level of the city's sewage shaft. The property is actually perfectly flat. According to information from the general contractor, apparently 80% of the builders no longer want a shaft in the technical room/laundry room. Regarding the sump pit: Is this a reservoir for wastewater that is then pumped to a higher level by a pump and then discharged into the city's sewage shaft? Another question: How do I protect my basement in case of flooding/heavy rain and water flowing back from the sewage shaft into the house?

Hi,

take a look at this video, maybe it answers your questions?
It's from the Stadtwerke Wuppertal regarding protection against basement flooding, etc.
