After prolonged use, faucets often develop leaks, leading to water wastage. So, how to repair a leaky hot and cold faucet in the sink? Let’s learn together!
How to Fix a Leaky Hot and Cold Faucet in the Sink
1. If the leak occurs at the joint between the faucet and the pipe, it may be due to a loose nut. In this case, you should use a tool to tighten the nut. It’s also possible that the internal U-shaped sealing ring has aged or been damaged. If so, you should replace the U-shaped sealing ring with a new one.
2. If the leak is at the gap under the faucet stem, it could be due to damage or aging of the triangular sealing ring inside the faucet cap. In this case, you will need to replace the triangular sealing ring with a new one.
3. If the leak occurs at the faucet’s outlet, the internal spindle washer may be damaged or aged. In this situation, you should replace the spindle washer with a new one.
How to Properly Clean and Maintain the Sink
1. When cleaning the sink daily, you should use a sponge or a soft brush. Never use hot water directly for rinsing, nor should you immerse the sink directly in hot water for cleaning, as this can lead to cracking. If you need to pour hot water into the sink, make sure to add some cold water first, as pouring hot water directly can also cause cracking.
2. After prolonged use, the drainage hose under the sink can accumulate a lot of grime. To ensure smooth drainage, it is advisable to regularly detach and clean the drainage hose. This not only effectively prevents the accumulation of dirt but also helps avoid the growth of bacteria and unpleasant odors.
This is a detailed introduction on how to repair a leaky hot and cold faucet in the sink and how to properly clean and maintain the sink. I hope it can help those in need. When your sink faucet leaks, be sure to first identify the specific location and reason for the leak, and then choose an appropriate repair method based on the actual situation.
