Water Supply Problems 
Water Supply System. 
I am enclosing a sketch of a water sys¬ 
tem I wish to arrange. The main point 
of my case is to know if I can draw 
water a distance of .300 feet through 
level pipe to pump and then lift it 30 
feet. It would be the best plan of course 
to place the pump nearer the well, but 
as this would mean putting in a cellar, 
etc., I do not wish to do so. as I have the 
system all going as illustrated, except 
that I am drawing from a well about 10 
feet from pump. This well, however, is 
very unsatisfactory, as the water is full 
of iron and very hard, and in Summer is 
almost dry. The well I wish to draw 
from has been supplying water since 
1720, is clear and soft and has analysed 
absolutely pure. A l^-inch pipe with a 
the top as suggested by It. A. D. While 
the water would syphon out, provided the 
pipe reached the bottom of the tank, if 
arranged with the discharge coming in 
over the top, it will give less trouble to 
lead from the bottom where all the water 
in the tank will be directly over the top 
of the pipe at all times. 
This system could still be used if the 
pump was not perfectly tight by putting 
a gate valve of generous proportions, so 
that the discharge of the pump would not 
be interfered with, between the pump 
and the lowest point from which it is 
desired to draw water. This can be 
opened while filling the tank, then closed 
point and strainer was driven 10 feet 
below bottom of well, so all water drawn 
enters at this point, though the water 
level is usually about 15 or 18 feet be¬ 
low ground level. In the driest weather 
I have drawn several barrels of water at 
a time, so it is a well worth connecting 
with the power system. As it is near en¬ 
trance to pasture I would like to retain 
a non-freezing force pump on the same 
pipe, which I now use to furnish water 
for cattle. The pipe to house would join 
just below’ cylinder of force pump. Do 
you think these conditions would be 
right? 
As shown in diagram, pump used is a 
rotary cam pump, 13 gallons per minute 
at 120 revolutions per minute. Suction 
pipe is 1^4-inch, 300 feet from pump to 
well. Delivery pipe one inch, 30 feet 
above pump to tank. n. a. d. 
Middleboro, Mass. 
The small rotary pump, when of good 
make and in good condition, is capable of 
the usual suction lift, i.e., about 25 feet, 
and is capable of a total lift, suction and 
discharge, the pipe below’ and above the 
pump, of around 75 feet. This of course 
means vertical length of pipe, and w'here 
the pipe is well laid with few bends and 
of good size, as is the case here, it should 
handle this water system without trouble. 
The addition of a foot-valve at the lower 
end of the pipe in the well would be a 
great advantage, almost a necessity un¬ 
less the pump was primed every time it 
was used. It would not be feasible 
though to have both pumps on the same 
suction line in the well; they should be 
independent of each other. This will 
not require more than 15 extra feet of 
pipe, which even at the present prices of 
pipe will increase the cost only about $2. 
If the outdoor pump is fitted with a 
two-way cock below the curb it can be 
connected by an underground pipe line 
with the watering trough and W’ater dis¬ 
charged through this pipe to the trough 
direct, or out of the spout above ground, 
at the will of the operator. A small vent 
drilled through the pipe between the cyl¬ 
inder and curb and below the frost line 
will of course make this a non-freezing 
pump, as the water remaining in the 
pump above this vent will discharge 
through it w’hen the pump is left after 
use. 
If the rotary pump and foot-valve are 
tight, permitting no leakage, the 30 feet 
of pipe above the rotary pump can be 
used for a service pipe of the house sys¬ 
tem as well as to fill the tank, resulting 
in the saving of considerable pipe. If 
this were done it would be necessary to 
have this supply pipe enter the tank at 
the bottom, as shown, instead of over 
until time to fill the tank again. This 
would also provide an easy means of 
priming the pump, if priming became ne¬ 
cessary, opening the gate valve permit¬ 
ting the water remaining in the tank to 
flow into the pump and prime it. 
R. ll. S. 
Air Obstruction in Water Pipes. 
R. II. S. says on page 1089: “A com¬ 
mon mistake in laying water pipe is the 
use of too small pipe.” No truth could 
have been stated in fewer words. For 
more than 50 years my grandfather con¬ 
veyed water from a spring to his house, 
a distance of 17 rods, through white pine 
logs bored out 3*4 inches, with a descent 
of only three feet. During all that time 
the water never stopped running except 
when purposely stopped to clean the 
spring. There was no trouble whatever. 
Logs, when constantly kept wet, and the 
pores filled with water, will last a great 
many years. When these logs began to 
leak my father (who had succeeded to the 
place) took them up and laid down lead 
pipe %-inch bore. It was a sorrowful 
mistake. Every little while—sometimes 
every two or three months—the water 
would stop running. Investigation 
showed every time that the stoppage was 
caused by nothing but air collecting in 
the pipe. ‘‘Only this and nothing more.” 
He usually got it out with an air pump. 
Had lie put down logs bored like the ones 
he took out, it would have saved him a 
great deal of trouble. 
When I succeeded to the farm, I laid 
a %-inch lead pipe to a spring to the 
west of the house about 20 rods distant, 
with a descent of five or six feet. Even 
with much greater fall the water was 
frequently stopped by air gathering in 
the pipe. My method of getting it out 
was as follows: I took off the strainer 
in the spring, fitted a piece of pipe 10 
feet long into the end of the pipe there, 
fastened it up perpendicularly, put a 
funnel in the upper end, and with a step 
ladder, and dipper, poured water into it, 
thereby increasing the pressure in the 
pipe going to the house, by the increased 
height of the fall. This increased pres¬ 
sure never failed of starting the obstruc¬ 
tion and it would soon move out and run 
for a time all right. In the course of 
time the hill which was the source from 
whence the spring was fed, and had been 
all woods, was cleared, and the spring 
dried up. j. w. ingiiam.

Pres. Wilson Urges You to Use 
Government Farming Records 
America must make up for the world’s 
food shortage,” said the President in his 
speech before the U. S. Chamber of Com¬ 
merce, ‘‘and the methods of our farmers 
must feed on the scientific information in 
the U. S. Department of Agriculture.” 
Millions of dollars have been 
spent by the government in experiment¬ 
ing and investigating the methods by 
which the soil can be made to yield more 
money to the farmer and stock raiser.
