How to replace the toilet cassette 

We replace an old toilet cassette with a new one. The first problem to overcome, in my specific case, was to bring the water to the upper-side part of the new cassette, since the old one has the water inlet in the lower part. It is a very old cassette and it shows as soon as I open it! For this purpose, I purchased a galvanized copper pipe that bends easily with the hands, and a tap to enter the wall. You will certainly need some plumber's Teflon tape, to wrap on the threads to avoid unpleasant water leaks.
