Hello. Your toilet is leaking through the flush valve. This is a serious issue as it will use a huge amount of water every day. Check to be sure there is not an obstruction in the tank and if you can not find one, call the plumber. J.

Hi, if you remove the cistern lid and flush the toilet, look at the float (back left) to see if this is rising freely when the water fills back up. Once the water has stopped filling, check the fill level lines on the large syphon in the middle of cistern. Your model of toilet has an eco flush which will be lowest line to save water, so not as much water will flush out. There is a long plastic screw on the float (back left) which you can turn to adjust the water level to the higher line on syphon (1.6 gallon flush) and turn it slowley till the water level reaches that mark. flush a couple of times to see it is filling back up to the set amount.

It may be the wax ring expanded and is restricting the flow.
If you did not install the unit FYI ..the wax ring is inserted between the toilet and the waste pipe to prevent leakage. Sometimes it moves out of place when the toilet gets installed and blocks the flow

Unless there is some packing material or protective film that you failed to remove it is more likely to be a problem with your home drainage system than the toilet itself.
It could be debris from removal of the previous toilet, a wad of toilet paper or other stuff partly blocking a pipe.
Before doing anything else get outside and open up the man-hole covers. Throw a bucket full of water down and see how quickly it drains away. - if it runs well then the problem is likely to be a blockage somewhere between the toilet and the drain cover.
I would suggest uninstalling the toilet bowl to make access easier then rodding it through with drain rods - you can usually hire these quite cheaply but they are only about £15 - £20 to buy a set in the UK.
