# 15 How to fix a leaking sink mixer
This video explains how to effectively change a flick mixer tap (these can be found in showers, kitchens, all sorts) which involves changing the cartridge. With reputable brands, replacement cartridges are easy to find however with others you may need to take it to a plumbing supplier to see if they can match it.
First turn off the water to the tap either by an isolating tap, or the main water supply. Turn the tap off clockwise, and make sure water is off. Look for button and cap, take it off. Use Allen key to take top of tap off. Now get shifter and unscrew the top anticlockwise. Pull cartridge out – they are all different. Put new cartridge in and screw in tight. Put locking, cover and head back on. Use Allen key to screw back up and turn the water back on.
