Step-By-Step Guide: How to Fix a Lead Pipe Leak
Step 1: Locate the Leak
The first step is identifying the source of the leak. Turn off your water supply and dry the pipe using a towel to pinpoint where the water is seeping out.
Step 2: Assess the Damage
Determine whether the leak is a minor issue or part of a larger problem. For small holes or cracks, DIY solutions often suffice. However, extensive damage may require professional intervention.
Step 3: Prepare the Pipe
Once youve located the leak, clean the damaged area using a wire brush or sandpaper. Dirt or debris can make it difficult for sealants or repair materials to adhere properly.
Step 4: Apply Temporary Fixes
- For tiny leaks, wrap pipe repair tape tightly around the area.
- Epoxy putty can also seal small damages effectively; knead the putty and press it firmly onto the leak.
Step 5: Perform Permanent Repairs
