How to Find Leaks in a Copper Pipe Behind the Walls
Copper pipes don't have the harmful buildup of galvanized steel pipes but they can still leak just like any pipe. Most of the piping system in your home is located in the walls of your home near the water faucets, toilets and other appliances that use water. If one of those pipes has a leak, you may not know until you see the physical evidence of it in the form of water spots. Finding the leak is the first step in fixing it. Does this Spark an idea?

Look on the walls and floor for water spots and dripping water. The first sign of a leaky pipe for most people is a water spot on a wall. However, the location of the spot is not the same location as the leak as the water probably dripped from the leak.

Look at a layout of your home's pipe system in the blueprints, if available. This way you'll know where all the pipes in your home are so you'll have a better idea of which pipe could be leaking.

Knock 1-inch holes in the wall around the leak area to see if you can find the leak. When you find it, mark the area by tying a cloth around the pipe so you don't lose it.
