Hooray!!! Now it’s finally done. But it took a little while. It seems that currently the skilled workers in the construction industry have quite a lot on their plates. The screw is now out. The craftsman surprisingly found it fairly quickly and unscrewed it.
My heating installer was quite taken with my story and even tried out three systems right away to be able to offer cleaning as maintenance in the future. So the following systems were used:
- Rotating brush (by Bösch)
- Cleaning balls (MAICO MF-R63)
- Cleaning set (by fd-ds)
We started with the exhaust pipe in the kitchen. The pictures show how it looked.
First, we tried the balls (MF-R75). You insert a ball into the pipe and suck it with a vacuum cleaner from the other side of the pipe. The ball stirs up the dust, which is supposed to be vacuumed off at the end of the pipe by the vacuum cleaner. After 3 runs, the ball was quite dirty. Since the balls are made of foam, we couldn’t get them properly clean anymore.
Despite the 3 cleaning runs, the deposits in the pipe were still clearly visible with the camera.
Perhaps this is because the ball almost covers the entire diameter of the pipe. For this reason, the airflow cannot build up sufficiently to transport the dirt through the pipe.
Next, we tried the rotating brush (by Bösch). The brush is turned by a cordless drill and pushed through the pipe via the flexible shaft. Here too, a vacuum cleaner is supposed to vacuum the stirred-up dust at the other end of the pipe. After cleaning, the dirt was barely visible with the camera (at least in the first 2 meters away from the valve). But cleaning with the cleaning set showed that it was not cleaned sufficiently after all.
It could be that the rotating brush blocks the airflow path too much. As a result, the active brush does not let enough airflow through to transport the dirt along the distance of several meters through the pipe. Thus, it could be that the stirred-up dirt in the pipe deposits again.
We cleaned the same pipe again with the cleaning set (by fd-ds). It works as follows: a pull cable is laid by means of a pulling unit, which is sucked in by a vacuum cleaner. The pipe is cleaned with a cloth on the foam body. This is pulled by the laid pull cable. The cloths on the foam body are changed after each cleaned pipe or after each run.
Despite several cleaning runs with the balls and the rotating brush, the cloths of the cleaning set came out quite dirty from the first pipe, which we used for testing.
All other pipes were done with the cleaning set. Without testing the systems on the first pipe, the entire cleaning took about 2 hours. The cleaning with the cleaning set looked quite simple. That’s why I’m considering whether to sign the maintenance contract or clean my pipes myself in the future.
