Step-by-Step Corrugated Hose Repair

Step 1: Cut Out the Damaged Section

Use a utility knife to slice straight through the center of the leak. Trim away the split and jagged edges until you have two clean, flat hose ends.

Step 2: Create a Male Joint

Take one of the hose ends. Use your utility knife to make a small, 1 cm horizontal slit along the very first rib valley. This allows the end to compress slightly and shrink its outer diameter.

Step 3: Twist and Interlock

Insert the slit end into the other untrimmed hose end. Twist the two sections into each other following the direction of the corrugated ridges. The ridges will act like threads, locking together seamlessly.

Step 4: Wrap and Seal

Once securely interlocked, grab a roll of heavy-duty waterproof tape. Wrap it tightly around the joint, overlapping each layer while pulling it taut to ensure an absolute airtight and watertight seal.

There you have it! A quick, zero-cost fix that saves an old hose from the landfill. Stop ignoring those pesky utility room leaks. Grab a knife and some tape, head over to your broken hose, and get it fixed today! Let's get making!
