How to Fix a Leaky Kitchen Faucet: Hot and Cold Water Repair Guide

When the kitchen hot and cold faucet malfunctions and needs repair, it typically requires disassembly first. Let’s learn how to disassemble and repair the kitchen hot and cold faucet.

I. How to Disassemble and Repair the Kitchen Hot and Cold Faucet

1. First, turn off the main water supply valve in your home. Next, remove the red and blue caps located under the faucet handle to expose the screw holes inside. Then, use a screwdriver to remove the screws, allowing the faucet handle to become loose. After that, rotate the faucet handle to take it off. If it’s too tight, you may need to apply some lubricant at the joint.

2. Once the faucet handle is removed, you will see a large brass nut. Use a wrench to unscrew this nut, which will allow you to take out the faucet cartridge. Then, identify the cause of the malfunction and take appropriate repair measures.

II. How to Repair the Faults in the Kitchen Hot and Cold Faucet

1. Carefully check whether the internal copper surface of the cartridge is uneven or whether there are any sand particles accumulated. If so, clean it thoroughly.

2. Remove and inspect the rubber sealing ring on the copper surface for any damage. If it is damaged, replace it with a new one. If you can't find the fault, consider replacing the entire cartridge with a new one and reassemble everything according to the reverse order of disassembly.

3. To effectively avoid issues like water leakage or difficulty turning the faucet, it is advisable to focus on regular maintenance and cleaning. If the ambient temperature is below freezing and you feel abnormalities when touching the faucet handle, pour some warm water over the faucet surface first. Once the temperature of the faucet surface increases, you can start turning the handle. Directly turning the handle in such conditions can lead to a decrease in the lifespan of the faucet cartridge.

The above is a detailed introduction on how to disassemble and repair the kitchen hot and cold faucet. I hope it helps everyone. After disassembling the faucet, it’s essential to find the cause of the malfunction and take appropriate repair measures based on the actual situation.
