Coincidentally, a connection cable of an outdoor luminaire in the garden was scratched. The outer shell was broken and also the blue neutral wire.
Several times I have wrapped the tape firmly and tightly around the pipe. For testing, I have then sprayed just once with the water hose to the pipe. The water has no chance. It does not penetrate through the belt.
Now I wanted to know whether it also keeps stood pressure.
Cut an old garden hose, so with pressure splashed the water through the interface.
Repair band drum and the water flow.
Behold, no water leakage at the interface. The band holds tight.
For small repairs or minor emergencies ideal and very recommendable.
In major components with defects such as a water pipe in the house I would however he prefers the line repaired professionally. Since I lack confidence despite successful test.
Small and practical tool. From me like 5 star. Function given perfectly.
