It became interesting, in what condition after three months the walls of the sewer corners and how clogged it is.
I begin to disassemble. This is done very simply, unscrew the nut connecting our pipes with the sink.
We bend over a homemade siphon in order to drain the liquid that acts as a water seal.
We remove the siphon completely and carry it to the bath for examination.
I expected there would be heavy deposits on the walls of the sewer fittings. But to my surprise, there were practically none. Photos are a vivid confirmation of this.
The photo above shows the pipes that were constantly in the water.
