Does anyone have any advice, im not sure if it a faulty toilet? or cistern? As the toilet is struggling to flush i have tried adjusting the flush setting and testing on minimum and maximum, and seeting the water level. But i never come across a toilet that struggles to flush and splash the soilet seat.


update:

they company are sending a new cistern hope fixes the issue

Pathetic flush!! Is it a new WC? It maybe a poor casting or the cistern may have a limited flush, some are down to about 2.5Ltr now!!

yeh brand new cistern and back to wall pan, this is 6 litres of water as well. My old closed coupled flush was a lot more powerful

Looks like a faulty WC. Speak to the installer or supplier.
