Leak test: Experiences related to it

Also request our wastewater disposal before the official connection. It costs something around 300€ and was handled by the GU (= shell constructor in our case). Additionally, a camera inspection is even required for us, so be glad you don’t need that as well.

Well, I think that's the most sensible and inverted money ever!

Shortly before pouring the screed, we noticed that a coupling had come loose ... unimaginable ... first time using the sink and then ...

And I’m also glad I did the blower door test, if only for the good feeling.

Blowerdoor doesn’t cost much and reveals defects. I would always do it.

In our area, the city requires an inspection of the wastewater systems every 10 years. However, we are also located in the [Wasserschutzgebiet]. The companies performing the inspections must be certified for this and carry out the inspection according to a specific standard. It cost around €300 and took 2 hours.
