If you have a blocked sink in Worley, Gloucestershire there are several methods that can be used to clear the blockage. Firstly try and use an ordinary household plunger - fill your basin or bath with enough water to cover the lip of the plunger and then plunge vigorously until any remaining air is forced from the plughole this may help unblock it without using more drastic measures such as boiling water or bottle plungers etc. If these steps do not work, you could also try one of two other methods including investing in a mechanized drain snake (or augers') which should scour out most blockages if they're minor; but for tougher ones manual force will need to be employed & assistance form someone experienced with plumbing issues would likely be best called upon here! Lastly pour 1 cup white vinegar mixed with 3 cups hot tap-water evenly down over entire area being careful not catch yourself off guard by too much steam when doing so. This method has been known amongst our customers at Drainage Gloucestershirervices company to work wonders time after time if successful on those hard-to shift raw sewage deposits like fat build-ups but always keep safety first priority whilst trying anything else!
