An adequate and we'll arranged wa
ter supply system contributes TO the
comfort and well being OF the family
to a greater measure than any other
form of household convenience. Such
system not only lightens the burden
of household drudgery. but adds i'm
measurably to the contentment OF
those who enjoy its service. when
there is added to the convenience OF
such a plant that of system OF sew
age disposal, the equipment OF the
suburban or country res !dence be-
comes as complete as can be obtained
where city water supply and sewer
service is available. That plants OF
this kind are in general use is
matter of, common knowledge and that
they are successful in service is at
tested by the number of companies
engaged in their manufacture.
A water-supply plant for the aver
age home need not be elaborate nor
expensive in order to be convenient
and efficient The water may be taken
from any suitable source OF supply
and the plant may be made to suit the
available conditions no matter what
they may be.
The water-supply plant shown In
! the drawing Is that known as the
pressure-tank system. 1t is simple in
| construction, not at all difficult to OPP
crate, and contains all Of the essen
| tails necessary to the demands of the
ACREAGE home. The picture includes
the pipes and fixtures for stationary
wash tubs in the basement, for bath
room and kitchen sink, and also the
waste pipes connecting with the house
drain. These features are included
| to show the possibilities of con-
venient and efficient system for the
average isolated home.
The source of water supply In this
case is rain-water cistern sunk be-
low the level of the basement floor,
the top of which extends above the
level of the floor. The water Is
pumped from the cistern by common
tank pump and forced into the press
ure-tank, as is clearly shown in the
drawing, where it furnishes the sup.
ply of water as desired. The tank
in this case, Is All upright cylinder
made perfectly tight and constructed
to withstand the necessary pressure
required to perform its service. II
may be galvanized as a precautiou
against rust, but this Is not abso
lutely necessary.
The pipe which conveys the water
the bottom and as the water enters
the contained air Is compressed into
the decreasing space above its surface
The pressure developed by the com
pressed air furnishes the force by
which the water Is driven out of the
pipes as the supply is demanded. This
Is a principle of physics known as
Boyle's law II the air In the tank
when empty of water, Is compressed
until it occupies one-half Of its orig
inal volume, then the pressure will be
| /
this case will be about 15 pounds tc
the square inch. The higher the water
rises in the tank, the greater will BIZ
the pressure developed. This may b.
as high as 1875 pounds to the square
inch, II occasion requires, but 4.
pounds pressure is generally sufilcien
for all the requirements usually de
manded in a house plant. These
pressures are easily attained with
for2e pump such as shown in tn,
drawing.
A glass gauge G., on the side o
the tank, Is intended to show tn,
height Of the water in the tank a
any time. and the pressure gauge w
shows the pressure sustained by tn,
water. The supply pipe rising from
