If you have a blocked sink in Elmbridge, Gloucestershire then there are several options available to help remove the blockage and restore your water flow. A simple method is to use an appropriate-sized plunger or plughole bend to try and dislodge any materials which may be causing the obstruction. If this doesn't work it could be time for more drastic measures such as using a bottle snake; these devices will allow you to access into pipes further down the drain ducts so that they can clear away stubborn bits of debris stuck behind them. Alternatively, if all else fails why not give boiling water with vinegar a go? This combination should do the trick just measure carefully before pouring! Finally, don't forget regular maintenance schedules - once again removing problems like scale build up which could eventually contribute towards blocking drainage systems in future.
