Electricity/Water/Sewer lines under garage

The blue pipe is the water line.

The suppliers will want a site plan anyway. We had three on-site appointments until we found a solution. It was a bit more complicated for us as well.

With us, it will now be done as originally planned - directly under the garage into the house. There will be no inspection shaft or anything like that. The builder and the water supervisor agreed that this is OK because, as has already written, the pipe will be laid in an additional PVC pipe. If something breaks, it will simply be replaced.

Interesting.
I have a similar situation. However, I will lay the pipe at the side about 1m from the garage.

Just a dumb question because it fits here right now.

In the past, the water pipe was a cast pipe or then a galvanized steel pipe. In my house, built in '64, a galvanized steel pipe comes into the basement.

I've read quite often now that nowadays the pipes are laid in protective conduits to be able to replace them later. For that, I would need a flexible pipe, otherwise I won't be able to get it through later. Usually, the protective conduit is not perfectly straight; I often have to go up through the floor slab.

What material are the water pipes usually made of that come into the house from the water supplier?

Usually, HD-PE pipes with double walls for drinking water arrive from the supplier.
Through your house entry, these could later also be replaced. Depending on the diameter, they are more or less flexible.

Inside the house, mostly metal-plastic pipes like Geberit Mepla are used.
You don’t have to put anything in empty conduits.
In Switzerland or Austria, the pipes are sometimes installed as a hose-in-pipe system. This allows them to be replaced quite easily. In Germany, I believe this is not even permitted.
In general, modern water pipes last almost forever as long as they are not semi-dry for years...
