A toilet that was previously functioning correctly now has a weak flush about 60% of the time. It is a modern toilet that came with a newly built flat I moved into three years ago. It does not have a handle but has a circular area in the lid which has two silver button type things within the circle that you press to flush. I am not sure how to take off the lid as if you try to take it off the lid does not come off but sticks to the toilet
Thanks
