Kitchen hot and cold water leakage method: 1, remove the handle, see the faucet parts. Use a large carp pliers or an adjustable wrench to remove the packing nuts, and be careful not to leave scratches on the metal. Rotate the spool or shaft in the same direction as you rotate when you open the faucet to turn them off. Remove the screws that hold the washers. If necessary, use osmotic lubricants to loosen the screws. Check the screws and spool, if there is damage to replace the new one. Close the water supply and remove the small screws above or behind the faucet handle to remove the handle that is fixed to the main body of the faucet. Some screws are hidden under metal buttons, plastic buttons or plastic sheets, and these buttons or plastic pieces are caught or screwed into the handle. As long as you open the button, you will see the handle screw on the top. If necessary, use some osmotic lubricants like the WD-40 to loosen the screws. 2, with a completely the same new gasket replaced the old washer. The new washers, which are almost perfectly matched to the old washers, generally allow the faucet to drip no more. You should also note that the old washer has a bevel or flat and is replaced with the same new washer. Only the gasket designed for cold water will swell violently when there is hot water to block the outlet, making the hot water flow slow. Some washers can work in hot and cold water, but you have to make sure that the gasket you buy for replacement is exactly the same as the original one. 3, the new washer fixed to the spool, and then the components of the faucet re-installed. Rotate the spool clockwise. After the spool is in place, reload the packing nut. Be careful not to let the wrench leave scratches on the metal. Reinstall the handle and replace the button or disc. Reopen water supply and check for leaks.
