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

Shut off the water and use a pipe repair clamp or self‑fusing silicone tape to stop the leak until a plumber arrives. For small pinhole leaks, epoxy putty can work once the pipe is dry. These are temporary fixes only.

Quick steps:

• Turn off the nearest shutoff valve and open a faucet to drain pressure.
• Clean and dry the pipe.
• Apply a repair clamp, silicone tape (stretch tight), or epoxy putty per package directions.
• Avoid duct tape; it will not hold.
