If it happened that you found a leak in the pipe, the very first thing you will have to do is to call plumbing.
At a time when you wait for the specialist’s arrival, you will need to stop the loss of water yourself. If water flows from a small crack in the pipe, then it will be possible to eliminate such a crack using a sealant or you can use a rubber gasket and a special tourniquet.
To do this, you will need to put a rubber segment on the pipe, and fix the tourniquet on top or, as it is called plumbing clamps. Such a clamp is easily put on the pipe and it can be well twisted with bolts.
You can still use the usual seal of a simple pencil, which should be inserted into the hole and leave it there. The neck will swell slightly under the influence of water and thereby stop supplying water through the hole in the pipe.
Epoxy glue for tiles has also shown itself very well, it is also used, which is often used to eliminate a small size of leaks. This is what pipe is applied to the surface and allow it to completely dry for 15-20 minutes.
