Discharge
Pipe Sizes
xXrhen the pump is some distance from the house or point of water
use, the discharge
pipe size should be increased
to reduce pressure
losses caused
by friction.

Tank
Tank is pre-charged
with 40 pounds
per square inch (PSI) air pres-
sure at the factory.
Your tank requires
an air charge of 30 PSI for
proper
operation;
check
tank pressure
with
tire gauge to deter-
mine if air charge
needs adjustment.
Tank pre-charge
should
be
checked
annually;
see instructions
at right.
In areas where
the temperature
is high for long periods
of time, the
tank pre-charge
pressure
may increase.
This may reduce
the tank
drawdown
(amount
of water
available per cycle). If this occurs,
re-
duce the pre-charge
pressure
to match the pump cut-in setting of
the pressure
switch
(normally
30 PSI).
It is necessary
to flush all air out of the piping
system
mad water
reservoir
portion
of the pre_harged
tank. This is required
on new
installations,
pumps requiring
repriming
and pumps that have been
disassembled
for service.
Do this as follows:
1. Open faucets furthest
from tank and allow pump to operate.
2,
Air in the system will cause a sputtering
flow; allow faucets to
run until you have a steady, air free s_.
3. Open and close faucets repeatedly
until you are sure all air has
been removed.
4. If stream does not become
steady, air may be leaking into the
system; check for leaks in the piping on the suction side of the
pump.
NOTICE:
To prevent
watedogging,
check tank air charge annually.
To Check Tank Air Charge
if drawdown
(amount
of water
available
per cycle) decreases
sig-
nificantly,
check
as follows:
1. To check
air charge in tank, shut off electric
power
to pump,
open faucet near tank, and drain completely.
2. At the air valve in top of tank, check air pressure
with standard
tire gauge. Air pressure
should be the same as the turn on pres-
sure of the pressure
switch
(30 PSI).
3. If the air pressure
is below
30 PSI, add air to the tank. Use an
air compressor
or a portable
air storage
tank.
4. Use soap or liquid detergent
to check
for air leaks around
air
valve. Continuous
bubbling
indicates
a leak. If necessary,
install
new core in air valve. This is the same as those used for auto-
mobile
tubeless
tires.
