A dripping faucet or leaking pipe can quickly turn from a nuisance to a costly plumbing headache. Before calling a pro like The Relining Company, try these surprisingly simple repair leaking pipe solutions to stop leaks in their tracks and avoid damage.

Snap-on a SharkBite

For small leaks in copper and PEX pipes, SharkBite connectors offer a push-fit solution. Just cut out the damaged section of pipe and deburr the edges. Select an appropriate-sized SharkBite coupling, lube the pipe ends, then push them firmly into each end of the connector. An internal o-ring seals the joint without requiring torches, solvents, or clamps. Voila – the leak stops.

Tighten up Compression Fittings

If tightening the packing nut on a compression elbow or T-joint doesn’t stop a drip, the nylon or rubber gasket inside probably needs replacing. Just unscrew the nut completely, pull out the old gasket, stretch a new one over the pipe, and re-tighten the nut. The leak should cease once the gasket sets. This method works on supply lines to faucets, valves, and under-sink appliances too.

Use Epoxy Putty Sticks

These handy moldable putties turn from soft to rock hard in minutes, creating a durable seal. Just roll a putty stick between your hands to activate, then wrap firmly over the problem area and smooth edges. Once cured, it adheres to almost any material – metal, plastic, fibreglass, wood, laminate, etc. It’s great for sealing leaks in pipe joints, threaded fittings, and around valve stems until you can replace the worn washers or gaskets.

Try Self-Fusing Silicone Tape

For temporary leaks in hoses, this specialized tape bonds only to itself, not to other materials. Just stretch and wrap it around leaking hose couplings to compress the seal. It flexes rather than cracks as the hose moves. Unroll more tape for a wider seal if needed. While not a permanent solution, it can buy you time until you can replace deteriorated washers or worn hoses.

DIY Pipe Clamps and Caps

Snap-style pipe repair clamps offer an instant seal for pinhole leaks in water pipes and supply lines. Clean and dry the pipe. Lube the inner gasket with silicone. Position the stainless steel clamp over the leak, then tighten the screw until the gasket seals tightly. Leaks gone. For capped ends of pipes, press-fit plastic caps insert firmly in place for a quick no-leak solution.

Whip Up Homemade Pipe Repair Putty

In a pinch, basic DIY materials can temporarily stop leaks. Mix cornstarch and white glue to create an adhesive putty. Work it into any cracks or punctures, smoothing with your fingers. You can also mix sawdust or shredded paper with flour and water into a thick paste to plug holes in pipes or seals. These solutions harden quickly to stop leaks fast before permanent repairs.

Know Your Limits

While effective for minor drips, DIY fixes have their limitations in durability and pressure tolerance. Call a licensed plumber immediately for any leaking gas lines, sewer pipes, or large-volume water leaks, as these require professional repair. If leaks persist despite your best efforts, don’t delay – it’s time to pick up the phone.


Armed with the right materials and techniques, many common pipe leaks can be quickly repaired by handy homeowners as a temporary solution or to prevent further damage until professional service is available. So before breaking out your wallet, reach for your toolbox – you may be surprised what solutions are within your DIY grasp.
