Drainage Gloucestershire is an experienced professional blocked sink company in Great Witcombe, Gloucestershire. Our team of experts can quickly unblock your bathroom sinks and other sinks efficiently with the aid of suitable equipment including plungers, drain rods or an S bend inserted into the plug hole to dislodge any blockages. In some cases boiling water may be sufficient but sometimes harsher chemicals such as soda crystals and baking vinegar will need to be used depending on what has been causing the blockage in question. We suggest starting by pouring approximately one cup bicarbonate soda down followed by two cups of white distilled vinegar; allow this mix react for 2-3 minutes before flushing through with hot water from its closest possible source (boiling kettle works well). If these methods do not work then it would advise consulting our Blocked Sink specialists who have more advanced available techniques at their disposal that are tailored toward each situation specifically!
