If you're having an issue with your toilet bowl overflowing, it can usually happen for two reasons. Firstly there could be a blockage in the drain of the pipe from below or even further down inside the main sewer line which will require investigation by a plumbing expert such as ourselves at Drainage Gloucestershire - call 03 9335 4755 to arrange our professional assistance.

Secondarily, if flushing your WC causes water to rise up over the top and out then this may mean that something is causing too much pressure on either side of the U-bend seal which prevents air entering when flushed allowing waste matter through but preventing liquid coming back into pan area resulting in overflow outside onto bathroom floor etc. In order to best address these issues we suggest calling experienced plumbing professionals who are able access an enquirer position underfloor, so they can inspect pipework configuration properly before recommending fast effective solutions Call us now on 3 9335 4755 -

Step one is to cover any flooring around the toilet with a towel or newspaper. This will help protect it from water that might splash out as you plunge the bowl.

Step two: Take your plunger and ensure its rubber flange fits securely over the hole in your toilet bowl. If needed, adjust by pushing down on edges of flange if too large or stretching it open slightly if too small using both hands (illustrated).

Step three : Put enough water into your blocked sink/toilet drain so that when you use the plunger there's sufficient depth for an effective seal between tool & surface being plunged usually by no more than 2-3 cm deep, but this may vary depending on size of item dropped inside! Ensure all air has been pushed out before attempting again then start plunging vigorously up & down ensuring each push fully seals against rimmed edge before releasing pressure quickly - doing about 8 quick pushes should do trick ! Be sure not to put full force behind plunges otherwise some dirty liquid could be forced back outwards towards yourself & other surfaces nearby which would require cleaning immediately afterwords. Good luck :)

Ifthisdoesn't work, consider calling in a plumber who can assess what kind of issue needs addressing such as simple blockage requiring auger snake device inserted through pipe junction OR further extensive works needed like replacing entire length perished sectional pipes etc they'll also have access specialized tools required diagnose exact problem area so best left professionals handle job properly!
