How to connect PP pipes without welding and make a collapsible water pipe for a garden

In the summer, to care for plants in the yard, in the country house or in the garden, water is needed, which is best supplied using a summer water supply. In autumn, it can be easily dismantled until next year. Moreover, for its installation, we can quite do without welding. This will save us money and time. Any adult who has never dealt with polypropylene pipes before will cope with such work.

Tools: gas wrench, source of thermal energy, cold water.

The process of connecting polypropylene pipes and fittings without welding

We heat the steel plugs on a gas stove or in the flame of a gas burner, if the work takes place outside, for 1-2 minutes.

We grab a plug with an internal thread with a gas wrench, put it on a piece of wood and press the end of the pipe into the plug strictly vertically, periodically turning until the end of the pipe rests against the bottom of the plug.

Then we cool the plug together with the pipe under running cold water for a few seconds and twist the plug with a gas wrench from the end of the pipe. As a result, we get a fairly high-quality thread on the pipe.

Next, using a heated second plug with an external thread, we thread in a corner at 45 degrees, pushing it onto the plug to the end and holding it in this position for some time. After that, we cool the connection under a stream of cold water and unscrew the plug from the corner with a gas wrench.

We wipe the threads on the pipe and the corner with a napkin and connect them along the thread until the shoulder on the pipe, formed during the formation of the thread, rests against the end of the corner. The connection is strong and tight. However, if necessary, the connection is easy to disassemble when it is no longer needed.

According to the already proven scheme, we form a thread at the other end of the pipe, which also turned out to be embossed and of good quality. We form the thread in the branch of the tee, as in the corner, with a plug with an external thread. It remains only to screw the end of the threaded pipe into the branch of the tee and tighten.

If there is no need for any branch, then a round rubber nickel can be installed in it and tightened with a plug.
