The toilet has stopped flushing properly: you have to pump the push button to make it work.
The flush is operated by air pressure. The plastic tube linking the button and the flush may have become loose or damaged.
What you can do
- Take the marble top off from over the toilet cistern. Don’t do this unless you are confident about re-sealing the marble neatly.
- Check to see if the plastic tube has become loose or damaged.
- (The top of the cistern clips on over the top of the cistern body.)
- Fix and/or replace as necessary.
If this doesn’t work
There may be damage or deterioration to part of the flush itself. Consult a plumber.
