Almost everyone faces problems with leaky kitchen faucets and learning the right skills and tools to repair them comes in handy in difficult times. All you need to do is find the correct replacement parts. You will also need the right tools at hand including Allen wrenches, screwdrivers and large slip-joint pliers.
Once you decide to fix the kitchen faucet, first examine from where the faucet is dripping. Once you determine whether the faucet is dripping from the base or end of the spout, turn off the water supply of the faucet using the shutoff valves under the sink. If those are not present, close the main water valve of the house. To relieve water pressure open the faucet in the center position. Also, cover the drain to avoid losing small parts down the drain. Remember the order and position of the parts as you remove them from the faucet. Record a video of the entire process or arrange the parts in order to make the reassembly process easier. Once all the parts are removed, inspect the interior of the valve for degenerated gasket or mineral deposits. Use fine nylon and/or vinegar to clean the parts and remove mineral deposits.
If the water flow is slow, then use a screwdriver to clean the plugged faucet holes. Also you can improve water flow, by unscrewing the aerator and cleaning it thoroughly. Before reassembling the faucet again, slightly open the valve to flush out any debris found during the cleaning process. After reassembling the faucet, gradually open the valves while the faucet is open in the center position. Let the water run from the faucet to remove any air in the pipes.
Another important step in fixing your faucet is finding the correct replacement part. You can find the replacement parts online if you know the model number of your faucet or you can take the faulty part to your local hardware store or buy your company’s repair kit. If you are still unable to find them, contact the faucet manufacturer and ask for guidelines.
Leaks that occur at the base of the spout are caused by worn out O-rings under the spout. Wiggle and pull them up to remove them from the spout for replacement. In a rotary ball faucet, if water is leaking at the base of the handle, then remove the handle and tighten the ring using a spanner. In a cartridge faucet, if water is dripping or there is an issue with mixing hot and cold water, then replace O-rings on the cartridge or the cartridge itself. Ceramic disc faucets contain a disc that controls the flow of water. These faucets are reliable and hardly ever need fixing. However, leaks in ceramic disc faucets are difficult to fix as they can be caused by worn out rubber seals or a broken disc. As locating a cracked disc is difficult, replace the seals initially and if the problem persists remove the ceramic disc and find a replacement from the plumbing supplies store.
