How to Fix a Leaking Pipe: 3 Quick Ways

Finding & Turning Off your Home's Water Shut-Off Valve | Roto-Rooter

When a pipe starts to leak, that can mean big problems for homeowners. A leaking pipe might not be visible immediately, leading to significant damage in the form of rotting wood and mold growth. That's not to mention the higher utility bills since your water will run nonstop.

As soon as you notice a leak, acting fast is key. Your first step should always be to turn off the water supply valve. Then, you can use an epoxy putty, apply pipe repair tape, or install a pipe repair clamp to stop the leaking pipe. Whether you're waiting for a plumber or want a temporary fix, here's how to fix a leaking pipe so it doesn't damage your home.

Step 1 – Turn Off the Water Supply to the Leaking Pipe

Before you attempt any repairs, always shut off the water. Turning off the water prevents more damage and allows you to work on a dry surface.

• Find the nearest shutoff valve to the leaking pipe, if available.
• If there isn’t one nearby, shut off the home’s main water supply.
• Open nearby faucets to drain the line and relieve pressure.

Step 2 – Identify the Source and Type of Pipe Leak

Once the water is off, locate the leak and determine its cause. Common sources of leaking pipes include:

• Pinhole leaks caused by corrosion
• Loose joints or fittings
• Cracks due to freezing or high pressure

Wipe the pipe dry and look for moisture returning. For hard-to-spot leaks, try these three clever ways to check for plumbing leaks.

3 Quick and Easy Ways to Fix a Leaking Pipe (Temporary and Semi-Permanent)

If you're wondering, "How do I fix a leaking pipe?" we have you covered. These quick methods can buy you time until a plumber arrives.

Use Epoxy Putty for Small Cracks or Pinhole Leaks

Epoxy putty is ideal for sealing minor damage on copper, PVC, or galvanized pipes. Here are the instructions on how to fix a pipe leak with this material:

1. Clean and dry the pipe around the leak.
2. Knead the putty until the color is uniform.
3. Press it firmly over the hole or crack and smooth the edges.
4. Let it cure according to the manufacturer’s directions.

Once cured, the putty creates a watertight bond.

Apply Pipe Repair Tape 

If you're wondering how to stop a leaking pipe at a joint or awkward pipe angle, try pipe repair or silicone tape:

1. Dry the area thoroughly.
2. Wrap the tape tightly around the pipe, overlapping with each layer.
3. Start a few inches before the leak and continue past it for full coverage.

The tape compresses and seals as you wrap, making it effective for low-pressure leaks.

Install a Pipe Repair Clamp or Coupling

When you want to fix a pipe leak that's larger or involves hairline cracks, use a pipe clamp or flexible coupling.

1. Clean and dry the pipe.
2. Place the rubber gasket over the leak.
3. Tighten the clamp around the pipe using a screwdriver or wrench.

In many cases, these solutions can hold for weeks or even months, especially on PVC or copper lines. They're one of the more common leaks you can fix yourself.

When to Call a Plumber to Repair a Leaking Pipe

Not every pipe leak is safe to DIY. It’s time to call a licensed plumber if:

• The pipe is corroded or cracked in multiple places.
• Water pressure caused the pipe to burst.
• The same section keeps leaking despite repairs.
• You can’t identify the source of the leak.

Professional plumbers can diagnose deeper issues, replace damaged pipe sections, and test pressure levels. They can also help prevent leaks in your basement that might cause serious damage to your washer, dryer, and other appliances.
