🚰 Common Reasons for Dripping Pipe Under Sink
A dripping pipe under sink can result from various issues that often go unnoticed until visible damage occurs. Here are the most common causes, often stemming from wear, tear, or improper installation. Regular checks can prevent these problems.
🔧 Loose Connections
Loose fittings between pipes often cause leaks. Water escapes through the gaps, leading to constant dripping and potential water damage. These connections, whether threaded or compression fittings, can loosen due to vibrations, temperature changes, or general wear and tear. Regular inspection and tightening of these connections can prevent such issues.
💧 Corroded Pipes
Older pipes, especially copper and metal pipes, can corrode over time. Corrosion weakens the structure, causing leakage and potential pipe bursts. This process is accelerated by the presence of minerals in the water, as well as the age of the plumbing system. Replacing corroded sections or the entire piping system may be necessary to avoid further damage.
🧰 Worn-Out Seals
Rubber washers and seals degrade with time, allowing water to seep through, which often happens in kitchen and bathroom sinks. These seals, designed to prevent water from escaping joints and connections, become brittle and lose their elasticity over time. Replacing worn-out washers and seals is a simple fix that can prevent a dripping pipe under sink and avoid persistent leaks.
🔩 Damaged P-Trap
A P-trap prevents sewer gases from entering your home. Misalignment or cracks in the P-trap can lead to leaks and unpleasant odours. The P-trap, a curved pipe under the sink, collects debris and prevents sewer gases from rising. Physical damage or improper installation can compromise its functionality, resulting in leaks and foul smells.
📉 High Water Pressure
Excessive water pressure strains pipes and joints, causing potential leaks, and can even lead to pipe ruptures. High water pressure can cause significant stress on plumbing fixtures, leading to premature wear and tear. Installing a pressure regulator can help maintain optimal water pressure and prevent costly damage.
🛁 How to Fix a Dripping Pipe Under Sink Bathroom
A dripping pipe under sink in the bathroom often occurs due to loose connections, faulty washers, or worn seals. Follow these steps to fix the issue and prevent further water damage. Always begin by shutting off the water supply.
🔨 Step 1: Turn Off Water Supply
Locate the water supply valve under the sink and turn it off. This prevents water from flowing while you work.
🧴 Step 2: Drain Remaining Water
Open the tap to allow any remaining water to drain out. This prevents water spillage during the repair.
🔍 Step 3: Inspect the Pipe for Leaks
Check for visible cracks, loose joints, or worn seals. Identify the exact source of the dripping pipe under sink before proceeding.
🔧 Step 4: Tighten Loose Connections
Use a wrench to secure loose pipe connections. Apply plumber’s tape to reinforce the seal.
🛠️ Step 5: Replace Damaged Washers or Seals
If washers or seals appear worn out, replace them with new ones. Ensure proper installation to prevent future leaks.
🧰 Copper Pipe Under Sink Leaking: How to Fix
Copper pipes are durable but prone to corrosion over time, leading to leaks. Fixing a dripping pipe under sink caused by copper pipes requires basic plumbing tools and techniques.
🔧 Step 1: Shut Off Water Supply
Turn off the water supply and drain any remaining water in the pipe.
🧼 Step 2: Clean the Pipe Surface
Use fine-grit sandpaper to clean the leaking section. Removing dirt and corrosion ensures a better seal.
🔥 Step 3: Apply Flux and Solder
Heat the pipe with a propane torch and apply flux. Melt solder around the joint to seal the leak.
🔩 Step 4: Replace Damaged Sections if Necessary
For severely damaged pipes, replace the affected section. Measure, cut, and solder new pipe sections securely.

🔩 Metal Pipe Under Sink Leaking
Metal pipes, though strong, are susceptible to rust and corrosion, which eventually lead to a dripping pipe under sink. Repairing metal pipes involves temporary and permanent solutions.
🛠️ Quick Fix Options
- Pipe Tape: Wrap plumber’s tape around the leak to create a temporary seal.
- Epoxy Putty: Apply epoxy putty over the leak to harden and seal the damaged area.
- Pipe Clamps: Use pipe clamps to hold damaged sections together temporarily.
🔧 Permanent Solution
If the pipe is severely corroded or damaged, replace it with a new metal or plastic pipe for long-term results. Opting for a complete replacement ensures the integrity of your plumbing system and prevents future leaks. Carefully measure the existing pipe and select a compatible replacement, ensuring a proper seal and preventing recurring issues.
