A leaky compression fitting can cause water damage, increase utility costs, and lead to system failures. Ignoring the issue may result in expensive repairs. Fortunately, fixing a leaking compression fitting is a simple process if you follow the right steps.
To fix a leaky compression fitting, first, identify the leak source, then tighten the fitting slightly. If the leak persists, disassemble the fitting, inspect for damage, and replace faulty components. Proper reinstallation with the correct torque ensures a secure, leak-free connection. If necessary, use plumber’s tape or pipe dope for added sealing.
Understanding the causes of compression fitting leaks will help prevent future issues. Read on to discover why leaks happen and how to fix them properly.
What Causes Leaky Compression Fittings?
Compression fittings can leak due to various reasons, including improper installation, over-tightening, or faulty components. One common cause is misalignment during assembly, leading to an uneven seal. Additionally, overtightening can deform the ferrule, preventing a proper seal and causing leaks. Another reason is worn-out or defective parts, such as cracked ferrules or deteriorated tubing, which fail to create a secure connection. Lastly, using incompatible materials can result in leaks, as different metals expand and contract at varying rates, weakening the seal over time. Identifying the root cause is crucial for an effective and lasting fix.
How Can I Fix It?
To fix a leaky compression fitting, start by identifying the source of the leak. If the fitting is only slightly leaking, tightening it about a quarter turn with a wrench may stop the problem. However, avoid over-tightening, as this can worsen the issue.
If tightening doesn’t work, turn off the water supply and disassemble the fitting. Inspect the ferrule and tubing for any signs of damage or wear. If any components are compromised, replace them with new ones. Before reassembling, clean the fitting thoroughly and ensure proper alignment when reconnecting.
Applying plumber’s tape or pipe dope on the threads can provide extra sealing. Reassemble the fitting, tighten it just enough to create a secure seal, and turn the water back on to check for leaks. If the problem persists, consider replacing the entire fitting to ensure a long-term solution.
Final Thoughts
Fixing a compression fitting leak is straightforward when you understand the causes and proper repair methods. Follow these steps for a secure, leak-free connection.
