How to Temporarily Plug a Leak in Galvanized Pipe
A leaky pipe in your home can cause all kinds of havoc, ranging from rot to major flooding. Leaks can result from faulty installation, freezing and thawing or even just regular wear and tear. In galvanized pipes used in the construction of older homes, the pipes have a tendency to rust from the inside out. Once one leak appears, it is likely that more will follow. Calling a professional plumber to replace the pipe is the best way to permanently fix a leak, but if you need a temporary fix to prevent more damage, you can take a number of steps. Does this Spark an idea?

1
Shut off the water source running to the pipe before attempting to fix a leak. This will stop the leak while you are applying your materials and prevent water from limiting the effectiveness of some adhesives.

2
Isolate the area of the pipe that has the leak. Remember that water can travel along the outside of the pipe before dripping off; be sure to trace the water back to its source to fix the correct place.

If the leak is relatively small, dry the area and apply a few layers of electrician's tape. Wrap the tape about six inches in either direction from the leak to ensure it is sealed properly. This fix is temporary, as the tape is not waterproof and will not prevent a leak from spreading.

Apply plumber's epoxy to the area if the leak is located at a fitting on the pipe. The epoxy comes in two colors. Take an equal size piece of each and knead together until it becomes a uniform color. Push the epoxy into place using your fingers or a putty knife. The epoxy will form a waterproof seal around the area so is a more effective plug for a larger leak or for one at a fitting.

Apply an automotive hose clamp and a piece or hose rubber or sheet cork -- this option is one of the most effective solutions for a leak. Hold the piece of rubber or cork over the leak and attach the clamp to hold it in place. These materials are readily available at most automotive retail stores.
