Can I fix a leaking pipe myself using epoxy putty or tape?

Yes, you can use epoxy putty or pipe repair tape to stop a small plumbing leak, but treat it as a short-term patch until a permanent repair is made. Most leaks start from corrosion, loosened fittings, or hairline cracks, and surface patches rarely address the root cause. Epoxy needs clean, de-pressurized pipe to cure, and tape works best on smooth, pinhole leaks; if pressure remains, the patch can slip. On Raleigh-area service calls, we often find quick patches fail because water seeped under the repair. A pro fix usually involves replacing the damaged section or rebuilding the joint.

Use these signals to guide your decision:

• Reasonable to patch: slow drip on accessible, non-rusted pipe.
• Call a plumber now: active spray, slab/foundation leak, severe corrosion, or hot line that won’t depressurize.
• Never use for gas lines; evacuate if you smell gas and call your utility.

Shut off the water main before any DIY attempt to reduce damage and risk.
