The water knot should never be used to join:
- Dyneema webbing
- Any webbing of unequal width
- Rope/cord to webbing

In these cases, the knot is very weak and prone to slipping.

The water knot can untie itself over time with repeated loading and unloading. Make sure the knot is tight and the tails are at least 10cm long each time you use it.

Some climbers duck-tape the tails to keep them neat and to help prevent creeping. If you do this, leave the ends of the webbing in view so you can see them.
