Step-by-Step Guide to Repair a Cracked & Leaking Water Pipe
1. Turn Off the Water Supply
Locate the main water shutoff valve and turn it off to stop water flow.
Open nearby faucets to drain remaining water from the pipes.
2. Identify the Leak & Clean the Area
Dry the pipe thoroughly with a clean cloth.
Use sandpaper or steel wool to clean around the crack for better adhesion.
3. Choose the Right Repair Method
For Small Cracks/Holes:
Pipe Repair Clamp/Epoxy Putty:
Wrap a rubber gasket around the crack.
Secure it with a pipe clamp or hose clamp.
Alternatively, apply epoxy putty, molding it over the crack (let it cure as per instructions).
Self-Fusing Silicone Tape:
Stretch and wrap tightly around the crack (overlapping layers).
It bonds to itself, creating a waterproof seal.
For Larger Cracks/Broken Pipes:
Pipe Replacement (Best Permanent Fix):
Cut out the damaged section with a pipe cutter.
Install a new pipe segment using couplings and solder (for copper) or PVC glue (for plastic pipes).
Slip Coupling/SharkBite Fitting (Quick Fix):
For temporary repairs, use a slip coupling (PVC/CPVC) or a SharkBite push-fit fitting (no soldering needed).
4. Pressure Test the Repair
Turn the water back on and check for leaks.
If using epoxy/tape, wait for full curing time before testing.
5. Monitor & Consider Permanent Fix
Temporary fixes (tape, epoxy, clamps) may fail over time.
For long-term reliability, replace the damaged pipe section.
Tools & Materials Needed
Pipe cutter/hacksaw
Sandpaper/steel wool
Rubber gasket & pipe clamp
Epoxy putty or self-fusing tape
Replacement pipe & couplings (for permanent fix)
Wrenches, soldering kit (if applicable)
When to Call a Plumber
If the pipe is in a hard-to-reach area (e.g., inside walls).
For major bursts or pressurized lines (e.g., main supply).
By following these steps, you can effectively stop the leak and prevent further damage. For a lasting solution, pipe replacement is recommended.
