I’ll tell you from my experience a month ago, I just didn’t go to this page before. We bought a hanging toilet a month ago, and for it we had to buy an installation. They chose German Groe, they speak well of her, they say, reliable, like a tank. All of us brought and put the guys from the store. The seller docked with the masters, they all did. After a couple of days, the regime of continuous flushing stopped turning off, the water pours and pours. I did not see anything good on the networks, but I did not find instructions. I thought that her masters were taken. I had to call the same men, they came a word, and at the moment all corrected. They showed me how to switch everything correctly, but by the way, I did just that. I ask what happened? They laugh, they say that everything is fine, just the drain is clogged. And what can a new drain clog? Something wrong. They left, and I found out from plumber friends that, most likely, the instruction itself was forgotten in the tank! They don’t need it, they know everything by heart, but they did not check the contents of the tank. It turns out that often the instruction is hidden in the tank, but not all of it is removed from there. It then soaks and prevents the overlapping of the hole. Here the water runs. Maybe it's a bike, or maybe this really happens.
