to place pitcher or other pump over
suction pipe to the we'll. The sue
ton lift should not exceed twenty
feet or the pump will not operate
satisfactorily, if at all. 1t should also
be remembered that water flowing
| through a pipe meets with consider
able resistance due to friction, which
increases as the velocity of the water
and the length Of the pipe increase
and as the diameter of the pipe d.
minishes. Elbows and bends in the
pipe greatly increase the friction.
Pump manufacturers give informa-
ton in regard to this FRACTIONAL loss,
which should always be considered in
arranging pumping system in the
kitchen or elsewhere.
An elevated water supply tank may
be placed in the attic, on the roof, on
the windmill tower, on special tower
or on the silo.> 1t must be high enough
to give the desired pressure at points
where the water is used. The tank
| may be Of wood or galvanized metal.
Its size will depend on the amount of
water used daily in the house. A 250
to, 500 gallon tank is sufficient for the
average family, although some have a
much larger tank, so that a supply suf-
ficient to last several days may be
maintained. A larger tank is also nec-
essary where water is supplied to the
house and barns.
The simplest system of this kind is
one with the tank in the attic or on the
roof, supplying water to the kitchen
only. When the expense can be af-
forded a hot water tank connected
with the range may be placed in the
kitchen and the water plumbing be ex-
tended to a bathroom.
The pump for this system must be
force pump, which not only raises wa
ter to its own level by suction, but
forces it to greater heights, according
to the power applied. The pump may
be placed over the we'll or in any other
convenient spot as long as the suction
lift does not exceed twenty feet. A
three way valve on such a pump per-
mits the operator to direct the water
to the tank or through the pump spout,
as desired. The pump may be operated
by hand, but where much water is to
be pumped to a considerable height
windmill, small gas engine or an
electric motor will save much time and
exertion. If the location Of the pump,
which should be convenient to the en-
CINE, necessitates long suction line
the size Of the pipe should be increased
and all unnecessary bends or fittings
avoided in order to lessen the friction.
The great objection to an elevated
tank system is that in the colder eli
mates there is danger of the water in
the tank freezing. This is particularly
Objectionable when the tank is located
In the attic, where considerable dam
age may be caused if it should burst.
1t Is also necessary to provide an es-
pecially strong support for the tank.
Another objection is that if located in
the attic the tank is likely to catch
considerable filth. It should in such
cases be easily accessible for more or
less frequent cleaning. It is we'll also
to cover the tank to prevent, as far as
possible, the entrance of dirt and
vermin, and when placed on a tower
outside it should be covered to pre-
vent the breeding of mosquitoes.
The great advantages of this sys-
tenn are it's cheapness and simplicity.
All that is needed are force pump, a
storage tank, pipe from the pump to
the tank, a pipe from the tank to the
point at which water is used and &C.
companying fixtures. The tank should
have an overflow pipe, particularly if
located in the attic
