Water leaking from a pipe into your home can cause serious damage to your walls, support structures of your home, and even the electrical system. So what should you do to stop the leak, and restore your plumbing? In this article, we’ll discuss a few steps you can take to repair a water leak and protect your home.

What You Need To Do To Protect Your Home


1. Start By Locating The Leak

First, make sure you know where the leak is. The source of a leak may be obvious in a basement or under a cabinet, so it’s easy to fix leaks in these areas yourself. If the pipe is located inside your walls, however, you may not be able to fix it yourself.

2. Turn Off The Water At The Source

Shut off the water supply to your home – then open all of your taps or attach a hose outside and run it until the water stops to drain your plumbing. Doing so will prevent further leaks and water damage.

3. Use Epoxy Putty To Seal Small Leaks

Epoxy putty hardens quickly when applied to copper pipes and plastic pipes alike, creating a barrier that seals small leaks and prevents further damage. Before you apply the epoxy, make sure that the surface of the pipe is clean and dry. If it’s dirty or wet, the epoxy may not bond properly, leading to further leaks.

Note also that this quick fix will stop further damage for a little while, but isn’t a permanent solution – call a plumber as soon as you can to have the leak inspected and get your pipe replaced.

4. Tighten The Pipe Joint (To Fix A Leaking Joint)

Plumbing leaks can occur at pipe joints if the joint is not tight. If it looks like the joint is the problem, tighten it up with a wrench. If a leak still occurs, there may be further damage to the inside of the pipe joint, so it will likely need to be replaced.

5. Cover Larger Leaks With Rubber & Hose Clamps

A larger hole or leak may be fixable with a strip of high-density rubber and hose clamps, which are available at the hardware store. Apply the rubber patch over the leak, and attach the clamps. Then, tighten the clamps to secure the rubber patch tightly over the damaged area.

Again, this is a temporary fix. We do not recommend turning your water back on. This method will simply prevent any further leaks or damage. If you do not replace the damaged pipe, the leak will likely get worse until the patch fails, and you may experience further water damage. Get in touch with a plumber for a more permanent solution.

Call A Professional Plumber To Finish The Job


If you have a large damaged section of pipe, a pipe burst, or heavy water flow from a leaky pipe, you probably can’t fix it on your own. Unless you know how to properly cut and re-attach water pipe, this is a job for a pro.
