Replacing pipes is not a spontaneous decision, and before doing so, you should decide on the performance characteristics of the proposed options, such as reliability, durability, strength, availability and ease of installation. Metal-plastic pipes are an affordable and environmentally friendly material that has found the widest distribution in water supply or heating systems. Due to the simple connection using fittings, even people with minimal specialized qualifications can install them. However, due to the low reliability of this type of connection, especially when using counterfeit fittings, which are present in huge numbers on the market, as well as their fairly high cost, the range of application of this type of pipeline is limited. In our opinion, the best alternative for water supply and heating systems is polypropylene pipes. Our specialists replace pipes with polypropylene ones in the shortest possible time. Their advantages include the highest durability, strength and low cost of not only the pipes themselves, but also the fittings. However, the installation of the pipeline has its own specifics related to the need for precise regulation of the temperature and time of heating the joints depending on the marking of the pipes, the quality of the preparation of the joints, the possibility of the appearance of burrs that reduce the permeability of the pipes. In this regard, for the installation of this type of pipeline, the company “Server-Service” recommends inviting only specialists with the necessary qualifications, which can be confirmed by the quality of previous work.
