Especially if you have a lot of old pipes and pipes in the house, it is good to have such a small "emergency responders" as this repair tape of scotch at home in order just in case, the waiting time until the craftsmen to bridge performs professionally the necessary repairs (without showing off the water supply throughout the house and therefore having to sit quasi in "dry", as with us already a lot). So I've bought this, specifically intended for short-term repairs to pipes or cables repair tape of scotch, hoping that it is capable of Emergency technically also be able to actually seal.
The principle works as follows: The tape should be very firm and wound overlapping around the site to be sealed, welded and thereby itself.
The Test: An old garden hose with a small crack had to serve as a test, and lo and behold, it works, even after repeated use of the tube holds previously sealed. Since neat "water pressure" is on the garden hose in use, I assume that in an emergency, a tube can be patched.
CONCLUSION: A cute, little domestic helper as a hedge for the emergency work and is therefore recommended.
