    Non-galvanized products, in addition, are subject to rust. Deposits inside the pipes is not only impede the flow of water on the upper floors of the building, but also worsen its hygienic properties, negating the "no" to water activities. It is obvious that this problem is widespread, so it was quite interesting to hear from experts and become familiar with practical recommendations to address this negative phenomenon. So, the mechanic energy section of the Moscow branch of CenterTelecom Vladimir Samburu, said: "At the moment the only way to restore the normal operation of pipelines is that they flush. Based on our practices, with a small thickness of sediments of some parts of pipe was washed with a strong jet of water, and for systems "experienced", we use compressed air. The velocity of water-air mixture in the process of cleaning must reach 2 – 3 m / s, the pressure air supply – at least 0.7 MPa at a flow rate of 5 – 6 m 3 per 1 m3 of water. The air is preferably delivered to the network periodically, at intervals of 1 – 3 min. Flowing into the riser air mixture boils and is well removed from the walls all deposits. Purification yields better results if you first before starting work in the tower to enter a small number of large salt crystals in which the flow acts like sandpaper ". Depending on the quality water used and the material from which pipes are made, this procedure should be performed every 4 – 7 years.
