Dangers of a Damaged Hose
Damaged hoses are dangerous. New hoses cost as little as $25, and prevent injury.
1. High pressure water forced through a small pin sized hole can be powerful enough to cut concrete or punch a hole in flesh. Do not try covering a puncture with your hand.
2. Taping, clogging, wrapping, or gluing a hole is not going to hold. The pressure will build up, then the patch will bust off, possibly causing severe injury or property damage.
3. A cut or hole in the hose near the end where you connect your wand is extremely dangerous because it's close to your arm when being used. Even without bursting, the high pressure leaking through the puncture can tear through the flesh in your arm.
