Step 10 · Test the Joint for Leaks

After all joints have been soldered and have completely cooled, you can test your work. Ensure all faucets are closed. Slowly turn the main water supply back on. Listen for the sound of rushing water filling the pipes. Once they are full, carefully inspect each solder joint for any drips or leaks. Use a dry paper towel to wipe around each joint; even the smallest leak will show up as a wet spot on the paper. If a leak is found, the water must be shut off, the pipe drained, and the faulty joint must be disassembled, re-cleaned, and re-soldered.
