Как спасти водопровод зимой? Греющий кабель внутри трубы

One of the most common problems in winter is the water supply to the house, especially if the building is on stilts or a columnar foundation. The water supply pipe is typically buried below the frost line and does not freeze. However, the vertical section where it enters the house is a vulnerable spot. I implemented a reliable heating system with a heating cable installed inside the pipe. This ensures the cable is reliably protected from rodents, mechanical damage, and other factors. The cost is extremely low if you build it yourself.
