Apologies for the non-technical expressions, I am not a native English speaker.
I have the following embedded water flush:
The problems with that water flush are the following:
- it usually flushes fine (90% of the time)
- sometimes, when full, the blocking mechanism does not work and the water keeps on flowing (1/5 cases of the remaining 10%)
- usually the water influx stops, then after a moment a tiny stream of water sips, with a faint sound of water (4/5 of cases of the remaining 10%)
- sometimes, when the water stopped normally a while ago, there is a small eruption of water flowing for about 2 seconds, and then back to normal.
I pinpointed the problem to "device A" - it moves up and down by approx 3 cm (ca. 1") and seems to be the "stopper" for the water. When something is wrong (the tiny stream of water for instance), I move it up and down and it is back to normal for some time.
The installation is about 8 years old and I suspect that the accumulation of calcium is creating too much friction for "device A" to move freely. The fact that this is not a constant behaviour could be explained by that too (I guess.
My question: is it something I can clean (by immersing in vinegar for instance), or should I plan to change that part (if it is changeable at all).
Bonus question: is this something someone like me (you can guess from the description that I am closer to an art major than a plumber, but I am ready to dig in) can reasonably do without damages to the family peace?
The device brand name is Geberit Aqua Clean
I noticed on the first picture that there is a guest in the water flush, a small spider
