Carsten (Kempinger Rohrreinigung Berlin @ YouTube; Kempinger GmbH) is in the mechanical room of a building where there is a blocked broken drain pipe in an awkward location behind some equipment. What appears to be wet wipes or paper towels are visible through the break in the pipe.

He removed a cleanout cover that’s in a segment of the drain pipe running along the wall next to the equipment that’s restricting access to the broken section of pipe. Once the cover is removed, he sends the high-pressure jetting hose up the line. This doesn’t seem to help disrupt the blockage, however. Even reaching the blockage is difficult due to the bends in the pipe.

Although it’s challenging to reach due to the equipment that is in the way, Carsten attempts to feed the jetter through the break in the pipe. Despite directly jetting the wipes or towels, they don’t break up. He fetches a long metal hook, and uses this to pull away some of the wipes or towels. This allows him better access for the jetting hose.

Back at the inspection opening he removed the lid from earlier, some wipes and sewage can be observed flowing past as he continues to jet through the break in the pipe. When sewage begins to back up out of the inspection opening, he does some more jetting from there. Soon enough, it begins to drain properly again. After some more jetting through the cleanout opening, he jets through the broken pipe some more.

With the blockage apparently cleared for the time being, he uses a jetting lance to try to clean up the area. While doing this, he demonstrates how the wet wipes don’t dissolve, even when directly jetted with the lance.

Carsten (Kempinger Rohrreinigung Berlin @ YouTube; Kempinger GmbH) is in a bathroom with a wall-mounted toilet that is draining very slowly. When the toilet is flushed, the water backs up in the bowl, before gradually draining away. He suspects that there’s something blocking it that has to be removed.

He removes the toilet from the wall, and empties the water inside it into a nearby bucket. The obstruction is clearly visible in the drain pipe within the toilet itself, and it appears to be a short-bristled rubber brush of some sort. The resident mentions having used it while cleaning the toilet, but accidentally lost it down the drain at some point, and wasn’t able to retrieve it using her hand. Carsten removes the brush, and disposes of it in a plastic bag.

With the blockage clear, Carsten remounts the toilet onto the wall. An initial test flush shows that it is draining much better than it did when he’d first arrived, although the water does still back up slightly. He does another flush, with some toilet paper, with the resident there to check if it’s flushing normally, and she suggests that it isn’t. He pours some buckets of water down, and does a test flush with a larger amount of toilet paper. It does seem to flush away, so there don’t appear to be any other significant obstructions. The customer seems satisfied that the toilet is flushing as well as it likely can.

Carsten (Kempinger Rohrreinigung Berlin @ YouTube; Kempinger GmbH) is in a bathroom with a toilet that isn’t flushing well. He takes the toilet off of the wall to inspect its drain, as well as the drain pipe it connects to. An inspection with a camera shows that there don’t appear to be any blockages in the toilet or the pipe, but there is some scale buildup in both. A chain attachment on a drain snake is used to try to dislodge some of the buildup from the pipe and the toilet, and what appears to be a bent screwdriver is used to manually help scrape some remaining buildup from the toilet’s drain in order to get it flushing properly.
