Although I have not exactly this type Unterspülkasten but 2 different predecessors. Unfortunately, I have been advised by my then this building material suppliers due to the best price. Had I already knew what a poor quality I would have expected me me of course decided otherwise. In short: With both UP-boxes already were numerous defects in everyday transportation on in my family house. There would be, etc. repeatedly broken mounts the actuator plates, stiff actuations, worn out diversions, defective bellows, defective drain bell, constant hunting, etc. Added to this are horrendous prices of spare parts and no Kulanzv manufacturer. I'd love to replace it with another brand, but as they fully installed and be tiled the effort is still too big to me ...
CONCLUSION: Do not buy !! Prefer to invest a little more and buy a reasonable concealed cistern another company!
