Duct tape can be used as a temporary solution to fix a leaky hose, but it is not a reliable or permanent fix. While duct tape is quite versatile and can adhere to a variety of surfaces, it is not specifically designed to handle the pressure and conditions that a hose may be subjected to.
Using duct tape on a leaky hose may slow down or stop the leak for a short period, especially if the leak is small. However, with time and exposure to water, pressure, and temperature changes, the duct tape may lose its effectiveness, and the leak could reappear.
For a proper and long-lasting solution, it's best to repair the hose using the appropriate materials and techniques. Depending on the type of hose and the location of the leak, you might use hose clamps, repair kits, or simply replace the damaged section of the hose. If you're unsure how to proceed, it's best to consult with a professional or someone with experience in hose repairs.
