What Is the Best Way to Seal a Leaking Pipe Temporarily?

Shut off the water, then seal the leak with epoxy putty or a rubber patch secured by hose clamps on a clean, dry pipe. These are short-term fixes until a plumber replaces the damaged section.

Quick steps:

• Turn off the main or fixture valve and relieve pressure by opening a faucet.
• Dry and clean the pipe around the leak.
• For pinholes: knead and press epoxy putty over the spot.
• For cracks: wrap a piece of rubber (old hose) and tighten 2 hose clamps.
• Avoid using near open flames.
