ᐅ Vigorous toilet flushing uses little water.

Hello,

I have the above-mentioned wall-hung toilet with a concealed cistern inside the wall. It is a compact bowl.
Why does so little water come out when flushing? Can you help me understand what might be causing this? Everything is newly installed, and the water supply comes from the pump behind it that works throughout the entire house.

I can't say anything specific about your system, but I have a wall-hung toilet with a short bowl that flushes poorly – and to this day, I don’t know whether it’s simply a bad design or if there were mistakes made during installation (maybe a pipe was cut to the wrong length or something...).

For us, it’s not a big issue because this toilet is used almost exclusively for urination...

That’s why we haven’t taken any effective measures so far...

Remove the actuator plate and take out the component inside the flush tank (fill valve). Usually, you can adjust the water volume that the valve allows during the flushing process there.
