Our tap is dripping and is driving me crazy! Am going to try and repair it myself but am struggling to figure out what kind of washer I should use and I'm a bit nervous of taking it apart until I have a plan of action. Suspect I need a ceramic cartridge as the taps are quarter turn Ones. Unfortunately I don't know what brand our tap is or how to get the right type of cartridge. Can someone help? Have attached pic of tap😃 Sorry I'm terrible at DIY but am desperate to sort this out x
