It is almost impossible to find a cast-iron toilet cistern in our time. The only stronghold of these "prehistoric" plumbing products were ordinary, secondary schools, of which there are a lot throughout the country.
Pay attention to all this "entourage" and this is a working toilet in high school. In the photo, as you can see, different stages of the life of the receiver of human waste are collected, I want to dwell on them in more detail:
- Under the number one the toilet seat is indicated, which was very common in the days of the Soviets - "concrete lining". The fact is that the toilet bowls were strengthened during construction with the help of wooden taffeta, I talked about ithere, over time, it rotted due to high humidity and the "white friend" loosened strongly, which led to breakdowns. Plumbers, in order to solve this problem, poured concrete into the lower part, this solution was very reliable for those times.
- By digit two the toilet is indicated without a rim, but this is a classic. At one time, in the 80s, I do not remember that my school had these elements of comfort. But it is worth noting that it is present on the neighboring one.
- Under third number, the drain pipe is already plastic, but as I know at the first stages of plumbing installation, drain pipes were used from iron, they quickly fell into disrepair. Because after draining the water was in a damp state and under the constant influence of oxygen from the air. Therefore, the transition to plastic in the 90s, to these "devices" has become a common occurrence.
- Under the number five, you see a modern remake, iron pipes could not tolerate a period of 10-15-20 years for cold water and hot water supply and they were changed at the same frequency. For polypropylene and flexible liners.
- And the oldest in the photo (4) we see a cast iron tank that has probably outlived everyone in this room, even a toilet bowl with a shelf. By the way, I wrote about these earlier here.
Why was the toilet cistern raised high up?
Initially, you need to understand why such a system was used at all:
- The cast-iron tank, as we can see, is durable, has been hanging for forty years. In the photo above, we figured out how he survived everyone. A plumber with hands can always fix it. You need a wire, a float and an accordion. Which can always be found on sale or in the rubble of the workshop.
- It is almost impossible to break the cast iron under the ceiling, it is now either the button is turned out, or the lid will be broken in public toilets at the faience brethren.
- It is impossible to steal such a tank, it is usually nailed with dowels, which was important in the 90s. The only thing is if modern "metalworkers" drag him to "ferrous metal".
And the most important advantage of such a water tank, raised to the ceiling. According to Bernouli's law and Torricelli's formula. The higher the liquid column, the higher the flow rate at the lowest point. Thus, he washes away absolutely everything in his path, laid out by a person. At the same time, the water consumption is the smallest than that of modern toilets. The cast-iron cistern under the toilet ceiling is the most elaborate element of the time!
