This instructional video could have you £’s in new taps. Often if you have a dripping tap and change the tap washer, the tap will still drip. At this point most people would give up and buy a whole new tap. Wait one minute and watch this video. It teaches you how to re-seat a tap. This means smoothing-off the metal plate that the tap washer presses against to create a seal. In hard water areas the seat can be prone to damage from scale but it can happen to all taps. Nevertheless a tap re-seating tool is a very handy piece of kit and can save you money. You can buy one here.
