One of the most common household plumbing issues is a leaky bathroom sink drain. This is not only a nuisance but can also lead to water damage and increased water bills. If you have noticed a constant dripping noise or a wet floor around your bathroom sink, chances are you have a leak. The culprit of this leak is often the jamb nut, a small but important piece of hardware that secures the drain in place.1. Identifying the Problem: The Dripping Bathroom Sink Leak
The jamb nut is a small, round nut that is typically made of plastic or metal. It is located at the bottom of the bathroom sink drain, just above the P-trap. The main function of the jamb nut is to secure the drain in place and prevent any water from leaking out. It is an essential component of the drain system and plays a crucial role in keeping the sink functioning properly.2. Understanding the Jamb Nut and Its Function
There are several reasons why the jamb nut may start leaking. One of the most common causes is wear and tear. Over time, the constant flow of water and exposure to harsh chemicals can cause the nut to become loose or damaged. Another reason may be improper installation, where the nut was not tightened enough or was not aligned correctly. In some cases, the jamb nut may also crack or break due to excessive force or corrosion.3. Reasons for Jamb Nut Leaks
If you have identified the jamb nut as the source of the leak, the good news is that it can be easily fixed. The first step is to turn off the water supply to the sink. Then, using a wrench or pliers, unscrew the jamb nut and remove it from the drain. Check for any cracks, damage, or buildup and clean the nut and the drain thoroughly. If the nut is damaged, you will need to replace it with a new one. If not, you can simply reattach and tighten the nut.4. Steps to Fix a Jamb Nut Leak
If you are not confident in your plumbing skills or if the jamb nut is severely damaged, it is best to call a professional plumber. They will have the necessary tools and expertise to fix the leak and prevent any further damage. Additionally, if you have tried fixing the nut and the leak persists, it may be a sign of a bigger issue with the drain system that requires professional attention.5. When to Call a Plumber
As the saying goes, prevention is better than cure. To avoid dealing with a leaky jamb nut, there are a few preventative measures you can take. Regularly check the nut for any signs of wear and tear and tighten it if necessary. Avoid using harsh chemicals or excessive force when cleaning the sink. Additionally, consider investing in a hair catcher to prevent any clogs and buildup that may cause pressure on the jamb nut.6. Preventing Jamb Nut Leaks
The jamb nut is not the only component of the bathroom sink drain system that can cause leaks. Other common causes include a faulty seal, a cracked drain pipe, or a loose faucet. It is essential to identify the source of the leak accurately to fix it effectively. If you are unsure, it is best to consult a plumber.7. Other Common Causes of Bathroom Sink Leaks
While a leaky jamb nut may seem like a minor issue, it can lead to more significant problems if left unattended. Besides wasting water and increasing your utility bills, it can also cause mold and mildew growth, which can be harmful to your health. It can also lead to structural damage to your bathroom, resulting in costly repairs. Therefore, it is crucial to fix leaks as soon as they are identified.8. Importance of Fixing Leaks
While some leaks, such as a loose jamb nut, can be fixed easily with basic plumbing knowledge, others may require professional services. If you are not experienced in plumbing, it is best to leave the job to a professional to avoid causing more damage. Additionally, a plumber can also provide a thorough inspection of the drain system and identify any other potential issues.9. DIY vs. Professional Plumbing Services
A leaky jamb nut may seem like a minor inconvenience, but it can quickly escalate into a bigger problem. By understanding the function of the jamb nut and knowing how to fix and prevent leaks, you can ensure a functional and leak-free bathroom sink. Remember, if you are unsure or unable to fix the leak, do not hesitate to call a professional for assistance.10. Conclusion: A Leak-Free Bathroom Sink

Once the jamb nut is removed, inspect it for any cracks or damage. If it's damaged, replace it with a new one. Also, check the rubber washers on either side of the jamb nut. If they are worn out or damaged, replace them as well.

Using your hands, roll a small amount of plumber's putty into a long, thin strip. Then, wrap the putty around the drain opening on the bottom of the sink. This will create a watertight seal between the sink and the drain.
Step 6: Reinstall the Jamb Nut
