Multi-utility house introduction for house with basement

We had a requirement from the [Stadtwerke] that we had to follow.

Yes, it was the same with us. The gas supplier prescribed one. The others didn't care.

The suppliers don't care about us. We are not getting any gas. What does the wall penetration of the disposal line look like at your place? Just a normal KG pipe?

Although [KG 2000] yes. Only floor drain in the boiler room and all drains in the [KG] are equipped with a non-return valve.

Is the KG pipe sealed to the outside in any way? For example, with a ring space seal? This was recommended to me today over the phone.

We also build basements with WU concrete. My Sanimann offered the standard ring space seal (TW, electricity, data, various cables) from Hauff. Delivery and installation 250 gross.

Is this an alternative for you to the expensive MSE?
