Quick answer: To stop a leaking or burst pipe right now — shut off the water at the main, drain the line by opening the lowest faucet, then make a temporary fix with a pipe repair clamp and a permanent one with a push-to-connect fitting. Most pipe emergencies are something a homeowner can stabilize in minutes with two cheap parts. Here’s the licensed-plumber playbook, plus how to prevent frozen pipes.

Complete guide to emergency pipe repair and winterizing, written by a licensed plumber, with the exact parts for each fix.

Step 1: Shut Off the Water Immediately

Find your main shut-off (where the line enters the house) and close it. Then open the lowest faucet in the house to drain pressure out of the pipes. Know where this valve is before an emergency.

Step 2: Stop the Leak Temporarily

A pipe repair clamp wraps the damaged section and stops a pinhole or split leak in about 60 seconds — enough to restore water while you get the permanent part.

Step 3: Make the Permanent Repair

Cut out the damaged section and join in a new piece with push-to-connect fittings — no torch needed, works on copper, PEX, and CPVC. (For in-wall permanent work, soldered copper is the lower-cost standard — see our SharkBite vs Soldered Copper guide.)

Step 4: Quiet Banging Pipes

If pipes bang when you shut off water (“water hammer”), a water hammer arrestor absorbs the shock and protects your joints from long-term damage.

Step 5: Winterize to Prevent Frozen Pipes

Frozen pipes are the #1 cause of winter bursts. Wrap exposed pipes with pipe insulation, cover outdoor faucets with faucet covers, and consider frost-free spigots for any outdoor lines. On freezing nights, let a faucet drip.

When to Call a Plumber

Call a pro if the leak is inside a wall or slab, you can’t stop the flow after shutting the main, or you smell gas near any work. Stabilize with a clamp first, then call.
