A defective plumbing joint is one of the most common causes of leaks in the home. Whether it’s a dripping faucet, a leaking siphon or a poorly sealed fitting, replacing or repairing a joint is a relatively simple operation if done properly. In this article, we explain step-by-step how to diagnose and solve this problem effectively.
Why do plumbing joints deteriorate?
Gaskets, usually made of rubber, silicone or fiber, play a key role in ensuring the tightness of fittings. However, they wear out over time due to factors such as :
- Prolonged exposure to water and chemicals
- High water pressure
- Overtightening during installation
- The natural degradation of materials
When a seal becomes defective, it can cause leaks which, if left unrepaired, can lead to further damage.
Identifying a faulty seal
Signs of a defective seal include:
- A visible leak at a fitting or tap
- Regular drips under a sink or basin
- Loss of water pressure
- Unusual noises in the pipes
To confirm the problem, disassemble the suspect part and inspect the seal. A cracked, flattened or worn seal must be replaced.
Replacing a plumbing joint: step-by-step
Step 1: Turn off the water supply
Before working on the system, turn off the water supply to prevent any leakage. Open the nearest tap or valve to drain any remaining water from the system.
Step 2: Dismantle the part in question
Using a wrench or pair of pliers, carefully disassemble the fitting, the valve or the component containing the seal. Take care not to damage threads or other components.
Step 3: Remove the old gasket
Remove the defective seal and inspect its location. Thoroughly clean the area to remove any residues of lime scale, dirt or old sealant.
Step 4: Install the new gasket
Choose a gasket of the right size and material. Place it correctly in its slot, making sure it’s properly aligned.
Step 5: Reassemble and test
Carefully retighten to avoid overtightening. Turn the water back on and test the installation for leaks.
Tips for lasting repairs
- Use Teflon tape on the threads to reinforce the seal.
- Opt for high-quality gaskets, which offer greater durability in the face of wear and tear.
- When tightening, use your hands to prime and finish gently with a tool to avoid distorting the joint.
When to call in a professional?
If the leak persists after the seal has been replaced, or if the installation seems complex, it’s best to call in a plumber. Some systems, such as concealed pipes or main valves, require specific knowledge to avoid further damage.
