ᐅ How can you identify drainage pipes embedded in walls or floors?

You’ll probably laugh at me again:

In our hallway, the drain pipe from the upstairs apartment runs inside the wall. It’s not exactly centered. I have a photo of the shell construction here. The entire wall is 3.90 m long (12 feet 10 inches). How long do you think one of those white blocks is?

Problem: I bought a wardrobe, and the middle part needs to be fixed to the wall with anchors. It would be really unfortunate to hit the drain pipe while doing that. I believe the calcium silicate brick is 24 cm wide (9.5 inches). So I guess I have to roughly count the blocks. Or is there another method?

If it’s a metal pipe, a metal detector will find it. If it’s an HT or KG pipe, you can tap on the wall to hear where the hollow pipe is located. However, some experience is needed for this.

I would count. If you have 3.9 m (12.8 ft) / 16 bricks (I tried to count carefully), you get approximately 24.4 cm (9.6 inches). So this should be fine, since there are 24 x 24 cm (9.6 x 9.6 inches) sand-lime bricks available. You probably need to position the wardrobe slightly to one side to avoid blocking the power outlets and network sockets.

By the way, what are all these network sockets next to the wardrobe for?

I would try tapping it.
A 100mm (4 inches) or 150mm (6 inches) PVC pipe is clearly audible inside the wall.

What do you tap with? And would furniture installers be able to do that?

So this should be fine, as 24 x 24 cm (9.4 x 9.4 inches) sandstone bricks exist. You will probably have to place the wardrobe slightly to one side to avoid interfering with the power outlets and network sockets.

By the way, why so many network sockets next to the wardrobe?

On the far left, I would put a nice old chair since the wood stove will be opposite it. Next, the chest of drawers (66 cm (26 inches) wide) with the phone on top and an old mirror (90 cm (35 inches) wide) above it, then the wardrobe (100 cm (39 inches) wide), and finally the cabinet on the far right (100 cm (39 inches) wide). The arrangement will be a bit loosely spaced.

I hope the wardrobe parts won’t necessarily have to be fixed to the outer wall but could maybe be positioned flexibly toward the center?
