    Since the author of the topic decided to install the installation in copper, I will only suggest that he should use gaps instead of elbows. Good luck in gaining new experience.

    There should be no solder joints under the floor or in plaster.




    Why shouldn't it? So you do all the installations on the top of the walls and on the floor? I understand industrial and technological installations on the surface.

    The solder connection, to the tin, is not a NASA technology and it sometimes lets go, with little care.
    it is different with silver or phosphor-bronze connections.
    So "mr. Mirrzo" is right.

    Installation done, working, no leaks. Everything is ok. The only drawback is that I gave too much tin and the gravity worked, so there were tin drops on the pipe, but they do not interfere with anything

    I apologize in advance if such a topic was already there.
    I am a layman in this field.
    He wants to connect the existing water pipes in the house with the new plastic ones (new point in the basement). I have a welding machine for plastic pipes at my disposal.
    How should I do it?
    Any advice, links to connectors. Is there such a possibility at all?
    and one more thing: the joint pipes should be about 10m in total (hot + cold water), the cold one should go to the gas stove and to the sink, and from the stove to the bathtub and to 2 sinks.
    Will I do it myself or should I hire a plumber? How much can the plumber's service cost for the execution of about 15m of joints?
    thank you in advance for your answer


    Glued plastic pipe + steel pipe, tow and grease, we twist
    Apparently, in such a connection, the plastic fitting should end with an external thread, i.e. when connecting to a steel pipe, screw it into, for example, a tee, a socket,

    Why, buddy, are you reheating the old cutlet?

Topic summary

The discussion revolves around connecting steel water pipes to plastic ones, specifically focusing on the use of copper as an intermediary. Various methods and tools for soldering and welding plastic pipes are mentioned, including the use of specific brushes for cleaning, soldering paste, and the importance of proper fittings. Participants suggest using brass couplers for connecting steel to copper and emphasize the need for appropriate fittings with internal and external threads. Concerns about the durability and safety of different materials, such as copper and plastic, are raised, with recommendations leaning towards using PP-R (polypropylene random copolymer) for its advantages in water installations. The feasibility of DIY installation versus hiring a plumber is debated, with some advocating for professional help to ensure leak-free connections, especially in concealed areas. The conversation concludes with a successful installation report, highlighting the importance of technique in soldering.
