How Water Supply to Buildings.
For domestic purposes the water is generally heated by means of a boiler at the back of a fireplace or by an independent boiler in the kitchen, burning coke or other suitable fuel.
The water supply may be intermittent or constant, usually the latter, whereby the mains are always full of water. By a Constant system is meant a system whereby the mains are constantly under pressure. The drinking water is taken direct from the rising main, and consequently it is only necessary to provide a small storage system sufficient for the hot water supply.. In cases where the water is turned off periodically, the system is known as the intermittent supply. In. this system, large storage tanks are necessary for the water, which is supplied for a short period each day.
( a ) The constant system has the following advantages over the intermittent supply: The mains are always full and an adequate supply of water may be obtained at any time.
( b) The danger of drinking water becoming contaminated is lessened owing to a direct supply) from the main and the avoidance of large .linage cisterns.
( c ) The pipes, constantly under pressure, are less liable to deteriorate. With the intermittent supply, a vacuum may be created causing strain on the pipe joints which may lead to gradual leakage.
( d ) In order to maintain a good fire-fighting service, a constant supply is necessary for the fire hydrants. An abundant supply of water can be obtained in the case of fire.
The chief advantage of the intermittent supply is the saving of water, but the constant system is usually preferred.
3. Put in the correct order:
water, mains, the, always, are, fuel.
the, main, drinking, water, rising, is, taking, the ,from, direct.
danger, of, the, supply, drinking, water, direct, to, a, owing, is, lessened, contaminated, becoming.
the, pressure, pipes, under, are.
a, hydrants, constant, supply, fire, is, necessary, for.
4. Explain how hot water supply to buildings.
5. Complete the sentences:
The chief advantage of the intermittent supply is the...

6. Answer the questions:
May the water supply intermittent or constant?
Are mains always full of water?
What is the a constant system?
Where is the drinking water taken from?
The pipes are under pressure, are not they?

Tank and Cylinder Systems.
A typical system installed in a small house with the well-known "boot boiler". This type of range boiler is economical and thoroughly efficient. Sometimes two boilers are interconnected, one behind the kitchen range and the other in the living-room or elsewhere. This arrangement has the advantage of supplying hot water irrespective of which fire is in use. An independent boiler is nowadays frequently specified in place of the kitchen-range type.
Tank system has such advantages as cheapness and good supply to fitting high up. And cylinder’s advantage is a good supply obtainable at lower fitting.
Fans are usually driven by electric motors, but other power may be utilized where electricity is not available.
With the tank and cylinder systems there are no control of the incoming air; therefore these systems can be only be employed successful where the surrounding are not noisy and windows can be opened admit clean air.
3.Find the Ukrainian equivalents:
- Expansion pipe
- supply cistern
- cold water supply
- branches of fitting
- safety valve
- “boot boiler”
- type of range
