Temporary solution to stop leakage from a pipe

[Downaski]

Is there any temporary solution for stopping water leakage from a pipe without replacing the whole pipe?

What type of pipe you’re working with? Different materials, like PVC, copper, or steel, sometimes respond better to certain repair methods.

Hi TinyTool! PVC.

Thanks for clarifying. For PVC pipes, here are a few effective temporary fixes:

One effective method is using waterproof or silicone tape. Start by drying the area around the leak to improve adhesion, then tightly wrap the tape around the pipe, stretching it as you go. Overlap each layer to create a strong seal, covering a few inches beyond the leak on both sides. This tape is designed to hold back water and can handle minor leaks quite well.

Another option is epoxy putty, which works well on PVC. The putty comes in a tube or stick form that you can knead to activate. Once it’s softened, press it directly onto the leak, molding it to the shape of the pipe so it completely covers the crack or hole. Allow it to cure as directed (typically 5–10 minutes to set, though full strength takes a few hours). Once hardened, the epoxy forms a watertight seal and is a great choice for slightly larger leaks.

Lastly, there’s the rubber and clamp method, which is especially useful for accessible, larger leaks. Wrap a piece of rubber—like a section from an old hose or glove—over the leaky spot, then secure it with a hose clamp. Tightening the clamp compresses the rubber against the pipe, effectively sealing the leak. This method is simple but surprisingly effective at holding back water until you can make a permanent fix. These solutions should help you manage a PVC leak quickly and effectively!

Thanks TT! How long do you think the epoxy will hold before needing a more permanent solution?
