The author is completely wicked, makes a penny stub, and even shows us - shame. Looking forward to the zen content analyst comments. But do not rush to conclusions, they will be at the end of the article. Before you scold me, let's get acquainted with the technology of manufacturing sewer plugs.
The arrow in the photo indicates the place where the cork is needed, around this hole will be filled with soil. And in order to prevent stones from entering the sewer, you need to insulate it.
But there is no plug at hand and you can buy it only in the city, and this is 30 km. there and another 30 back... Of course, you can push a rag or bag inside, this is usually done. But there is a more reliable option from the available means.
To do this, we need an ordinary water bottle, a 50 mm piece of pipe, of which there is enough lying under our feet during the installation. We cut the bottle as shown in the photo:
We put it on the sewer pipe
For further actions, I moved to the location of the stub. I will insert the branch pipe into the branch.
I light the burner (you can use a hair dryer) and begin to smoothly heat the plastic tube, gradually rotating.
Due to the fact that the bottle returns to its original state from heating, it shrinks and begins to tightly fit the pipe.
The plug is ready, no need to run somewhere to the store, go to the city. Did it right away, on the spot, without unnecessary movements.
