I would like to express my gratitude to Yaroslav Vladimirovich Trotsky, director of Kremensky V. K., and his team for promptly shutting off the water in my house on Vatutina Street. Now I am very far from my home, but after learning about the burst of water supply, I called the director and despite the very difficult time, the work was done. Thank you. With respect, Fedorchenko A. Ya.
