To troubleshoot a copper sink leak at base, you must first isolate the source of the problem. You may be able to identify the source of the water by locating the source of the water. For instance, a leak can occur at the spout, on the base, or at the mounting nuts. Remove the spout and clean it with a clean, lint-free cloth. If you still see water in the bowl, you might have to replace these parts.


Tighten the handle


Usually, the leak starts when the faucet is turned off. In such cases, you may have to tighten the handle of the faucet or adjust it after using it. A small drip can add up over time and cost you more money in water bills. Additionally, a constant drip can stain the sink. These signs indicate that you need to replace the kitchen faucet. If you"re unable to find a replacement part, you can try some other methods to solve the problem.

Replace the valve


The most effective way to fix a Kitchen Faucet leak at base is to replace the valve. You can either replace it completely or replace it by simply tightening or loosening the packing nut. However, if this doesn"t work, you can try grinding the metal valve seat. Be sure to use a specialized tool for this job. This method can lead to more expensive repairs, so it"s always better to seek professional help to fix a faulty kitchen faucet.


Turn off the cold water line


To determine whether you need to replace the valves in your faucet, try shutting off the water supply to the sink. You can try turning off the cold water supply first, but if the leak still persists, you can turn off the cold water line to find out if it is the source of the leak. Once you have ruled out the source of the leak, you can go on to the next step. If the faucet is still leaking, you should replace the valve.

Replace the valves and o-rings


The next step in fixing the kitchen faucet leak at base is to remove the valve and its retaining nut. You can also check the spout by placing a paper towel or a cup underneath it. It is possible that the leak has occurred in the ceramic disk. Then, you must replace the valves and o-rings. Once the o-rings are replaced, you can move on to sealing the base plate.


Check the O-rings


You can also check the O-rings in your faucet by disassembling it. Firstly, unplug the water supply. Once the valve is disconnected, check the spout by rotating back and forth. Afterwards, you can inspect the o-rings. If you suspect the O-rings are the cause of the leak, lubricate them with a food-grade petroleum jelly.
