red summer I would love you when there was no

00:00:04

dust, no heat, no mosquitoes and yes flies,

00:00:07

Sergeich Pushkin wrote this a long time ago, if

00:00:09

he lived now, he would definitely have added

00:00:13

mosquitoes and flies,

00:00:16

these utilities are already without

00:00:20

rhyme, of course, but still on topic I would like

00:00:22

to add words that he also knew because it’s

00:00:25

incomprehensibly hot, people are sweating,

00:00:28

they all turn off the hot water, we had

00:00:30

prophylaxis, what kind of prophylaxis, that you can’t

00:00:33

make prophylaxis twice as long

00:00:35

and then not turn off the water for two years, and what is

00:00:37

needed every year? I lost my hand

00:00:40

on this topic, in short, we decided

00:00:42

to find out this question: who

00:00:44

is turning off the water for us and why and sent our

00:00:46

best killer correspondents

00:00:48

to make a story about it, look

00:01:17

why I’m doing this, think man

00:01:23

option 1, the heat station decided to cheat, the

00:01:28

water will be turned off and the money will be counted

00:01:32

no man, you are wrong, to be

00:01:36

convinced of this, just look into the basement

00:01:38

of your house through these pipes, water

00:01:41

flows into the apartments, how much the house

00:01:44

consumes, the general house meter counts, it is

00:01:47

impossible to wind it up, the

00:01:50

flow of water passes and turns the impeller

00:01:53

connected to the magnet

00:01:56

from the outside, 2 magnets spin and rotate the

00:01:59

gear system,

00:02:01

and the dial shows the quantities of

00:02:04

water passed through

00:02:06

now and the meter is not moving,

00:02:09

which means the water is not flowing and you won’t have to pay

00:02:13

[music]

00:02:15

version number two,

00:02:17

maybe the water is poorly purified and it’s

00:02:21

clogging the pipes

00:02:26

no man, you’re wrong again

00:02:30

[music]

00:02:31

at the treatment plant the water passes through

00:02:33

filters at the bottom of a one

00:02:36

and a half meter tank a layer of sand and coal,

00:02:39

it retains all unnecessary impurities and

00:02:43

passes water

00:02:44

like in ordinary household filters,

00:02:48

then the water is sent to membrane

00:02:50

filters;

00:02:51

these are many thin tubes through which

00:02:55

even the smallest dirt will not slip through,

00:03:00

then option number three saves, because

00:03:05

if you turn off the water for the entire population of

00:03:07

the planet at least for one day it’s

00:03:10

scary to imagine how much water will be

00:03:12

saved

00:03:16

no man this is the wrong answer the

00:03:19

amount of water on earth is invariably

00:03:23

not no which can be pumped out to a drop q the

00:03:26

water evaporates and returns in the form of

00:03:29

rain less and and does not become

00:03:32

then option number four is a conspiracy and

00:03:36

they deliberately spoil pipes for a man

00:03:40

this time you are right as right, why

00:03:45

deliberately spoil the pipes and then swallow and

00:03:48

all summer it turns out there is a reason to

00:03:51

do just that and this is not a

00:03:54

conspiracy at all, how does this happen? valves

00:03:57

shut off the water supply in a

00:04:00

huge area,

00:04:02

then turn on the pump that pumps

00:04:05

water into the pipes when the operating

00:04:07

pressure is several times higher,

00:04:12

after some time the instruments record a

00:04:14

drop in pressure,

00:04:16

this means that on a selected section of

00:04:19

the pipeline there has been a rupture somewhere,

00:04:23

why is this necessary?

00:04:28

Let's look at the example of

00:04:30

bicycle tubes.

00:04:39

it will give out air bubbles

00:04:44

with the pipeline, almost the same story,

00:04:47

somewhere on the site there is definitely a

00:04:50

section of oil tank that can

00:04:53

break through, for example in winter when it is

00:04:55

difficult to live without hot water,

00:04:59

besides, the soil will freeze so much that it

00:05:02

will be very difficult to dig it, which is why in

00:05:05

the summer they go to deliberate a

00:05:07

breakthrough in the section, but how can we now find the

00:05:11

leak, because it is underground, to find the

00:05:14

leak you will need an acoustic

00:05:16

leak detector, these two sensors need to be

00:05:19

installed on pipe section 1 at one

00:05:23

end of the second at the other so that the place of the

00:05:25

suspected leak is between

00:05:28

them, the sensors fix and transmit an

00:05:31

acoustic signal, turn on the sensor and the

00:05:35

leak detector this signal processes and

00:05:37

provides information at what distance the

00:05:41

sensors need to dig, the exact location is

00:05:44

determined using a locator and a

00:05:47

measuring wheel, the

00:05:49

ultrasonic locator sees where

00:05:52

the pipe is laid underground and the wheel

00:05:55

determines the required distance, the

00:05:57

area is fenced off for passers-by and onlookers,

00:06:01

this is no place for you, wait, but if a

00:06:04

pipe bursts here, then where did the water go,

00:06:07

why does it

00:06:11

end up underground around the branch? pipes with hot

00:06:14

water are laid at an angle and

00:06:17

are located in a concrete gutter; as

00:06:20

soon as the water breaks through the pipe, the

00:06:23

nearest well flows out through the gutter; these wells are

00:06:27

covered with hatches with letters, etc. what

00:06:30

does the heating network mean,

00:06:32

by the way, this hatch

00:06:35

[music]

00:06:37

let's check

00:06:38

[music]

00:06:40

but all the water from

00:06:42

the well needs to be pumped out using a

00:06:46

submersible pump

00:06:50

and we can start digging

00:06:53

asphalt here, excuse me by the

00:07:06

way, if the pipes were completely renewed,

00:07:09

they would only

00:07:12

turn off the water in weak areas not for two weeks, it’s

00:07:15

six months

00:07:16

[music]

00:07:20

but here it is, a broken pipe, a

00:07:24

damaged piece, workers cut it out with a

00:07:27

gas cutter,

00:07:30

oxygen is supplied through one hose, and in another way, acetylene

00:07:33

gas burns and a cutting flame is formed

00:07:37

that easily copes with steel

00:07:42

by the way, pipes, although the rest are too

00:07:45

strong water friction and the walls also

00:07:47

wear out,

00:07:49

so they also require an annual

00:07:52

check

00:07:53

[music]

00:07:57

but now steel pipes are gradually

00:08:00

being replaced with

00:08:02

polyurethane foam; they are much stronger than

00:08:04

their steel predecessors and the

00:08:07

friction force in them is less, so soon the water

00:08:11

will no longer be turned off at all

00:08:13

[music]

00:08:17

and we just have to weld a new one

00:08:20

this time the pipe is already using electric welding,

00:08:25

so if you are asked why they turn off

00:08:29

the water in the summer, the answer is the following: at this time,

00:08:32

workers pump water into the pipes under

00:08:35

pressure so that the pipeline

00:08:38

ruptures somewhere, this will be the weakest and

00:08:41

potentially dangerous section of the pipe, they

00:08:44

find it and change the weak link

00:08:49

by the way man, they have already given you hot water,

00:08:54

the water has begun, the open is over, but there was

00:08:58

no need to worry so much,

00:09:08

but in India it is so hot that,

00:09:11

on the contrary, they don’t insulate warm pipes,

00:09:14

but insulate cold pipes, or rather, they don’t even

00:09:17

insulate, but insulate the heat so that the water does

00:09:20

not heat up inside these understand the pipes

00:09:22

and let the hot water flow, it won’t

00:09:24

cool down anyway, by the way, interestingly in India, they

00:09:27

probably turn off the cold water in the summer

00:09:32
