This document discusses different types of valves and pipes used in water supply systems. It describes ball valves that control the entry of water into storage tanks and ensure water supply stops when the desired water level is reached. Air valves are also discussed, which allow air to escape from pipes and prevent backflow of water into main lines. Both direct and indirect cold water supply systems are covered, with indirect systems using storage tanks to stabilize pressure and ensure supply during disruptions. Common pipe materials like galvanized steel, PVC, UPVC, polyethylene and copper are listed along with their advantages such as durability and ease of installation.

2.  7.1-Describe the type of valves and pipes, and the
country where they are used.
1.8-Discuss the system directly and indirectly in
the supply system, cold water
1.9 Discuss the benefits of supply-
direct and indirect cold water.
1:10-Music chart in the water supply
system for developing countries.

4.  PAIR AT HOME IN THE PIPELINE.
FUNCTION:
To stop the flow of water when there
are repairs the water mains.
Sufficient
water pressure to control the remote users.
Discard the dirty water in the main pipe.

6.  INSTALL THE WATER
SUPPLY PIPE AT HOME AS THE LOW PRESS
URE:
Distribution pipes of the water storage tank.
Low pressure heating system.
WHEN THE VALVE IS OPENED: there will be
no obstacles in the water.

8.  PAIR OF STORAGE TANK IN THE
WATER TANK AND SPRAY.
FUNCTION:
Controlling the entry of water into the tank.
Water
supply will stop automatically when the desire
d water level has been obtained.
BALL VALVES OPERATED IN
NATURE buoys.

10.  AIR TRAVEL USED FOR ONLY ONE WAY.
IMPEDE FLOW BACK INTO THE
WATER MAIN CHANNEL.
IF THE PAIR OFF, THE WATER WILL
BE OUT.
THE PAIR IN: hot
water pipes, pumps and piping branch near fix
ture.

12.  DETERMINED BY TYPE
OF PIPE AND FITNESS OF PURPOSE.
PIPES OF INTEREST:
Durable.
CAN HOLD HIGH TEKAANAN.
THE EASY INSTALL.
SAFE USE.

13. 1. Galvanized steel pipe (GL)
2. Pipe PVC (polyvinyl chloride)
3. Upvc Pipes (Unplasticied Polivinyl Chloride)
4. Pipe PE (Polyethylene)
5. Copper Pipes

15.  Known also as a system without a tank.
All sanitary fittings are supplied with cold
water directly from the main pipe through a
pipe service.

18.  Known also as systems that use storage tanks.
Water from the kitchen sink tap is
supplied directly from the service pipe.
Water bath, toilet and basin water supplied fro
m storage tanks.

19.  In this system, water from the
main pipe through the service pipe will be
transferred tothe storage tank water first.
Storage
tank, water distribution pipes into the distribut
ion pipes to the rules of gravity.
The purpose of holding tanks is to solve
the problem of water supply in the event
ofdisruptions in the water.

23. KELEBIHAN KEKURANGAN
 Kurang risiko
pencemaran air.
 Tidak semua tempat
pengeluaran akan
mendapat air jika
berlakunya gangguan
bekalan air.
 Tekanan air adalah
tinggi.
 Boleh menyebabkan
berlakunya gegaran air
disebabkan tekanan yang
tinggi.
 Pemasangan dan
penyelenggaraan mudah.
 Tekanan air rendah pada
waktu punca.

24. KELEBIHAN KEKURANGAN
 Tekanan air stabil di
semua punca pengeluaran
air.
 Tangki simpanan perlu
diselenggarakan.
 Tangki simpanan
berkapasiti tinggi untuk
menyimpan air yang
mencukupi semasa
gangguan bekalan air.
 Mempunyai risiko
pencemaran air daripada
tangki simpanan air.
 Dapat mangelakkan
berlakunya gegaran air
kerana tekanan tidak
terlalu tinggi.
 Pemasangan dan
penyelenggaraan sukar.
