I found I had a rusted section of pipe in a hard to reach place. My house is over 50 years old and has a lot of metal plumbing (as opposed to PVC). I couldn't remove the pipe without removing the entire tub, so I sat down, had a beer, and voila!

You won't need many tools, so let's get started.

Step 1: Materials and Tools

The bare essentials are the following:
1. Aluminum can.
2. Something to cut thin aluminum.
3. Metal vent hose clamps.
4. Flat head screwdriver

I recommend:
1. Some sort of bathroom (silicone
etc.) caulk.

You can buy aluminum that comes rolled up with adhesive on one side, but:

1. I didn't need that much.
2. The adhesive might come unglued when wet.
3. The aluminum is much thicker, usually for auto body work or small plane repair.

Step 2: Prepare Aluminum

The very first thing to do is:

Drink the contents of your can! (This might be the first project where you drink BEFORE you start.)

Once the can is empty and clean, proceed to cut the top and bottom off. Then, cut the can down the middle.

My multi-tool was perfect: the blade handled the big cuts and the scissors handle the split very easily.

Step 3: Size the Aluminum Around the Broken Pipe

Wrap the aluminum and trim excess if necessary. I had to cut off a 1/4" on one side to get it to fit.

Step 4: Apply Caulk to Aluminum

I applied silicone caulk on the aluminum that would be on the sides of my ruptured pipe. It serves two purposes:

1. It helps hold the sheet in place while fastening.
2. Once dry, it will help keep water from leaking out the sides of the aluminum.
