What is the most commonly used patch in pipe repairs?

The most commonly used patch in pipe repairs is the EWARP patch. EWARP, which stands for Emergency Water Activated Repair Patch, is designed specifically for quickly and effectively repairing leaks in pipes. This type of patch is made from materials that can respond to water activation, allowing for an immediate solution in emergency situations when quick and reliable repairs are necessary.

Despite the presence of other patch types, such as metal, rubber, and jubilee, EWARP patches are favored in many scenarios due to their ease of use and quick application process. They can conform to the pipe's shape and create a strong seal, which is critical during emergency repairs where time and integrity of the repair are essential to prevent further damage.
