Temporarily Fix a Leaking Water Pipe

Edited by Anonymous, Jerry Rivers, Lynn, Eng and 6 others

Fix a leaky pipe

These predicaments always seem to happen at the worst times. You are home for the holidays, turn on the kitchen faucet, and suddenly you see a stream of water shooting from a "pinhole" leak in the pipe! You know that today it will cost double for a plumber to fix it since it's a holiday. If you could just wait until tomorrow. Fear not my friend. You can be the plumber for a day, and temporarily fix that leaky water pipe yourself. You can also repair it with very little expense. Read on to solve this dilemma easily.

Repairing your leaking water faucet depends on three things:

  • The composition of the water pipe.
  • The location of the leak.
  • The size of the leak.

The most common pipes found in homes are either galvanized steel or polyvinyl chloride (PVC). To learn how to temporarily, and pretty easily, fix the leak of either of these kinds of pipes, follow these the instructions below.

Supplies Needed if you Have a Leak in a Galvanized Steel Pipe:

  • Small can or tube of epoxy for galvanized steel.
  • Small section of pliable rubber.
  • Putty knife.
  • Cloth to wipe the leak area until dry.
  • Two hose clamps that will fit around your pipe and rubber pad.
  • Screwdriver that fits your hose clamps' screw heads.

Steps to Fixing a Leak in a Galvanized Steel Pipe:

  1. 1
    Shut off the water supply to the damaged pipe.
    If there is no shut-off valve, you will have to find the main water shut-off valve outside your home. It will typically be near the street. Often it's in the basement.

  2. 2
    Open all of your faucets to drain the residual water from all of your water pipes.
    This will prevent water from dripping on the area around the leak.

  3. 3
    You must wipe the leaky hole and area completely dry before the next step.
    Was this step helpful? Yes | No | I need help

  4. 4
    Apply only epoxy over the hole that is for repairing galvanized steel.
    Ask for help at the hardware or plumbing supply store if needed. You will need a small putty knife to smooth the epoxy over the hole and area.
    Was this step helpful? Yes | No | I need help

  5. 5
    Press a section of pliable rubber over the leak.
    A remnant of a typical garden hose will suffice if a square of a thin piece of rubber is not available.
    Was this step helpful? Yes | No | I need help

  6. 6
    Set the hose clamps over the rubber piece, on each side of the hole.
    Was this step helpful? Yes | No | I need help

  7. 7
    Screw down the hose clamps until tight.

  8. 8
    Give the epoxy glue the instructed time to dry.
    It will require one or two hours. Once dry, turn the water back on.

If the Leaky Pipe is Polyvinyl Chloride (PVC)

It's just as easy to fix the leak if the pipe is PVC. Cut out the section of pipe around the leak. Then use a couple of fitting joints and replacement PVC pipe. The good news also is that these parts and supplies you need are inexpensive.

Supplies You'll Need If The Leak Is On A PVC Pipe:

  • Measuring tape.
  • Marking pen.
  • Fine tooth saw �" Do not use a hacksaw.
  • Small can of PVC pipe glue.
  • 80-grit sandpaper.
  • Cloth for wiping the pipe dry.
  • Two pipe couplings.
  • PVC primer.
  • PVC solvent cement.
  • Pair of work gloves.

Steps to Fix Your PVC Pipe Leak

  1. 1
    Shut off the water supply valve to the leaky PVC pipe.
    If there is no shut-off valve, shut off the water main valve to your home. It will be located near the street. Often it's in the basement.
    Was this step helpful? Yes | No | I need help

  2. 2
    Open all of your faucets to drain any trapped water from your water pipes.
    This will clear out any water that may drip on the surface around the leak.
    Was this step helpful? Yes | No | I need help

  3. 3
    Measure and mark a one-foot section of the leaky pipe with the hole at its center.
    Cut out the section at the marks.
    Was this step helpful? Yes | No | I need help

  4. 4
    With your sandpaper, sand the two cut edges until they are smooth.
    Was this step helpful? Yes | No | I need help

  5. 5
    Use the cloth to wipe the edges and area inside/outside the two sections of the original pipe to ensure they are completely dry.
    The PVC cement will only stick to dry surfaces.
    Was this step helpful? Yes | No | I need help

  6. 6
    Do not apply the PVC cement yet.
    Place the two coupling parts onto the cut ends of the pipe. This is to check the distance between them for now.
    Was this step helpful? Yes | No | I need help

  7. 7
    Measure the distance between centers of the two couplings.
    This distance will be the length that you cut the new PVC pipe. Take off the fittings for now.
    Was this step helpful? Yes | No | I need help

  8. 8
    Cut the new section of pipe at the measured length.
    Smooth the inside and outside of your cut edges with your sandpaper.
    Was this step helpful? Yes | No | I need help

  9. 9
    Put on your work gloves to prevent the primer and solvent cement from irritating your skin.
    Was this step helpful? Yes | No | I need help

  10. 10
    Apply PVC primer to the inside of one end of one coupling.
    Let it dry for about 10 seconds. Then apply an even layer of the solvent cement to the outside of only one end of the original pipe.

    Was this step helpful? Yes | No | I need help

  11. 11
    Slip the glued end of that fitting over the glued end of the original pipe.
    With pressure, twist the coupling one-quarter turn each way once on the pipe. Your pipe should be at the center of the coupling. Hold all cemented parts about 15 seconds so that they will hold permanently.
    Was this step helpful? Yes | No | I need help

  12. 12
    Perform this same step for the other coupling.
    Was this step helpful? Yes | No | I need help

  13. 13
    Apply the PVC primer to the inside of each coupling now for the new section of pipe.
    Apply the cement to each end of the new pipe section.
    Was this step helpful? Yes | No | I need help

  14. 14
    Insert the new section of pipe into each coupling.
    Twist the new pipe one-quarter turn in each direction, with pressure on each coupling to make sure that it is at the center of both couplings.
    Was this step helpful? Yes | No | I need help

  15. 15
    Allow the PVC solvent cement to set and dry for a few minutes.
    Was this step helpful? Yes | No | I need help

  16. 16
    Turn on your water, and check the replaced pipe at the glued couplings.
    You should have a permanent mend to the pipe. If so, no call to your plumber will be needed for a costly repair

Warning:

  • Be cautious of the PVC primer and solvent cement. The vapors from each will not only cause dizziness, but will endanger your health.
  • Have the area well ventilated while using the primer and cement. Avoid inhaling the vapors.

I have a leaky galvanized pipe that juts into the foundation.

I have a leak near the thread area of a galvanized pipe that juts out to the foundation and outside. When I take a shower or run the sink upstairs, this particular pipe leaks a little water where the threads are present before it curves into the foundation. Currently, I have a little bucket collecting any water that drips near the thread area underneath. This pipe runs from upstairs to downstairs but curves into the foundation. Does that help? (The steel pipe is about 5- 8 inches in diameter) Any suggestions?
