Successfully Patch A Leaking Metal Pipe

A leaking pipe outside of your home can cause flooding in your yard and may increase your water bill considerably. Learn how to temporarily repair the pipe with the following steps. The patched pipe will no longer leak and will make it possible for you to use your plumbing until you can have the problem fixed by a plumber.

Materials

  • soapy cloth
  • scrub brush
  • water hose
  • towel
  • metal file
  • plumbing putty
  • putty knife
  • plumbing tape
  • bucket of water
  • disposable gloves

Inspect The Pipe And Clean And Sand It

Turn on the water supply and go outside. Inspect the pipe to determine where it is leaking from. After you find the damaged area, turn off the water supply. Clean the damaged surface with a scrub brush and soapy water. Rinse the pipe off well with a water hose and dry the metal surface with a towel. Sand the damaged area with a metal file. Use firm pressure as you move the file back and forth. Sanding the pipe will roughen up the metal surface and make it easier for the plumbing putty to adhere.

Apply Putty And Tape

Put on a pair of disposable gloves to keep your hands protected from the putty. Mold a small amount of putty between your fingers until it is soft and pliable. Press the putty onto the cracked portion of the pipe until it adheres. Smooth out the surface of the putty with a putty knife. Wait a couple hours for the putty to harden.

Submerge a roll of plumbing tape in a bucket of water for several seconds. The water will activate the epoxy in the tape so that it will bond with the pipe. Gently squeeze the roll of tape to eliminate excess water. Unroll the tape and wrap it evenly over the putty covered section of the pipe. Press your fingers into the surface of the tape to help it bond to the metal. Wait for the tape to dry. 

Turn On The Water

Turn on the water supply and inspect the pipe to make sure that it is no longer leaking. The plumbing putty and tape will last for several days and prevent the damaged portion of the tape from becoming worse. Then set up an appointment with a plumber to have the pipe repaired or replaced. Keep an extra supply plumbing putty and tape in your home in case a different pipe becomes damaged in the future.
