How to bump into a pipe under pressure to install a ball valve

Installing a ball valve is not the easiest task that an owner can face. It is even more "fun" if you need to make an emergency mounting of this part by cutting it into a pipe under pressure without turning off the water. However, you should not worry ahead of time, since there are old and proven ways to implement such an event..

What you need: ball valve, tie-in clamp, steel thread, fumlenta

Before starting work, it is necessary to clean the pipe from paint in the place of the future installation of the ball valve. Once this is done, we take the welding machine and weld our thread to the pipe. Next, fumlenta or flax is put on it, and then the ball valve itself is placed. This completes the first and simplest stage of work.

Next, you need to open the already installed tap, arm yourself with a battery tool and the widest drill bit that can get through the hole of the open ball valve. All you need to do is drill a hole in the pipe behind the valve for water to enter. The work is very delicate. It is imperative to wear protective glasses on your eyes, gloves made of waterproof material on your hands, and it will be useful to protect the drill with a bag.

After the completion of the work, it remains only to paint the place where the paintwork was removed.

Note: also in the course of work, you can use an adapter specially designed for such operations. It is good because it allows you to embed the crane without using welding. In this case, a rubber gasket is mandatory under the adapter. The rest of the operation is not much different from that described above. The device is fixed with a few bolts and nuts.
