Required tools and materials.
Soldering plastic pipes is a simple process, since the main property of plastic, in addition to strength and durability, is a low melting point. It is enough to have an ordinary electric soldering iron and you can connect two elements without special equipment.
The sequence of this type of work is as follows: 
- The electric soldering iron is heated for 5 minutes to a temperature of about 260 degrees;
- Apply the soldering iron to the edge of the pipe, heat it to the desired state and quickly press it for gluing;
- It is enough to wait 5-8 minutes for the plastic to cool down and get a strong product.
This method is very useful when it is necessary to replace or repair the plumbing or sewerage that was damaged. It is enough to cut off the damaged area with a special knife and solder a new one.
Any start of work is accompanied by the acquisition of the necessary tools and supplies needed to implement the solution of the task.
The main tool, without which you can not do - is the above-mentioned soldering iron, which is connected to the mains. Buying such equipment is not a cheap pleasure, so you can rent or borrow. Do not forget to read the instructions that will give you information on which connector and the temperature you need to warm up. Do not forget also about the safety precautions when using an electrical appliance.
In addition to the soldering iron you will need: 
- Special sharp knife or saw( hacksaw) for cutting plastic;
- Measuring instruments( caliper, roulette), as well as a marker or pencil;
- Heat-resistant mittens to protect hands from burns;
- Liquid for degreasing surfaces( gasoline, white spirit, etc.)
Phased work.
Before you begin the process of soldering, carefully inspect the location in which you will work, the availability of the location of the pipes, as well as the availability of all the necessary tools. Do not forget to cut off the water in the aqueduct as well.
The next stage is the preparation of the pipeline section, which includes pipe cleaning, fitting and mating of structural elements.
Let's consider in more detail the process of preparation and soldering of plastic pipes: 
- Pipes should be dried dry and cut at a place requiring replacement;
- With the help of nazhdachki or knife, clean the trimmed edges;
- Be sure to make measurements to determine the diameter and thickness of the pipe wall, they influence the choice of the required temperature;
- Using a soldering device with a special nozzle of suitable diameter, melt the resulting cuts and gently join them together, fix this position for a while, or rather until the resulting weld has completely cooled down. In this case the hands must be in mittens;
- The quality of the seam is easy to determine by the small uniform convexity that formed around the entire circumference of the pipe.
After 30 minutes, you can safely start using the water pipe.
Additional recommendations.
To ensure that the process of soldering plastic pipes is successful, especially if you are doing it for the first time, we advise you to follow these simple recommendations: 
- Try to observe the correct sequence of work;
- All necessary parts should be kept at arm's length so that you can take the right one at any time;
- Have an extension cord available, in order to connect a soldering iron to it, if necessary;
- Observe the temperature and time modes, this will ensure the quality of the work done.
