How to Repair Leaky Pipes Quickly

Tighten a threaded joint with a pipe wrench if the leak is there. If that doesn't stop the leak, it may at least slow the leak until the joint can be replaced. (Note: Some older plumbing may require brazing - a kind of welding. If the pipe has no threads, or you see signs of welding, leave this technique to the professionals.)

Plug a very small hole by sticking the tip of a sharp pencil in it. Break off the tip in the hole and cover the hole with duct tape, wrapping it in several layers.

Alternatively, apply epoxy putty specially formulated for leaks caused by cracks or small holes.

Fix larger holes by clamping a piece of hose around the pipe. With a knife, cut a length of hose at least 2 inches longer than the hole. (Rubber hose or even an old piece of garden hose will do.) You will also need three hose clamps. Slit the hose lengthwise and fit it around the pipe, then clamp the hose in place using a hose clamp at each end and one in the middle.

Discontinue use of the leaking plumbing or catch the spillage with a bucket until proper repairs can be made.
