How to Fix a Leaky Kitchen Sink Faucet
To fix a leaky kitchen sink faucet, you must first identify the cause of the leak. Most faucets are not that expensive, and they usually have two shut-off valves, the hot and the cold. Before you begin, you should first turn off the water in the faucet, either using the valve under the sink, or by shutting the water main. Once you've turned off the water, remove the handles and all decorative parts, such as handles and knobs. Next, unscrew the stem and the packing nut. Replace the stem, if it's damaged.
Turn off the water source
In most cases, the problem is related to the drain. To diagnose the cause of the leak, you should turn off the water source. You can then remove the drainage pipe, clean and replace it. Afterwards, you can seal the valve and connections with plumbing putty. If the drain seal is damaged, a new one may be necessary. It's important to remove any debris that might be sticking to the drain.
Check the valve
Sometimes, the problem might not be visible at first, but if it becomes persistent, you can take steps to solve the problem. Check the valve and the cartridge at the main water valve, as the leak may be coming from the cartridge. Sometimes, mineral buildup can wear away the valve. If the valve is not turning off, it means the leak will continue. Generally, the leak is located at the base of the spout.
Need to cover the drain holes
