Always be sure to equip your well system with a proper Pressure
Relief Valve. This should be capable of discharging the full output of
the pump at or below the maximum working pressure of the lowest
rated component in the system. See the owner’s manual for your
pump for output information. This is vital for safe operation of the
well system. THIS PRODUCT COMES WITH A 5 YEAR WARRANTY.

How To Install The Tank

1. Find the fuse or circuit breaker
panel for your house. Turn off the
power to the well pump.

in this manual must be followed
to minimize the risk of electric
shock, property damage or
personal injury. Properly ground
to conform with all governing
codes and ordinances.

2. Open a faucet inside the house
as close to the tank as possible.
Drain the system as much as
possible by letting the water run
until it runs out.

3. Close the ball or gate valve (this
is the valve that controls the
flow of water from the tank into
the plumbing system inside the
house) (Fig. 1)

4. Close the ball or gate valve on
the pump feed line, the pipe
through which the pump draws
water from the well into the
house. (Fig. 2) This stops water
from running back into the well.

5. Drain the pump system.

Place a bucket under the drain

nearest the existing tank. Or, run
a hose from the drain into a
bucket or floor drain. Loosen a
union coupling over the pump
using the pipe wrench and the
adjustable wrench. This will let
air into the system and let the
water run out. Loosen until the
water flows out. Let the water
run out of the system.

If there is no drain near the

tank, open the pipe union closest to the tank using the 12”
adjustable wrench or the 12” pipe wrench. If there are no
union couplings, use a pipe cutter to open the pipe. Insert a
coupling to re-close the system when you are done draining
the system. (Fig. 3)

6. If there are union couplings in
the piping, loosen all three union
couplings close to the tank using
the pipe wrench and adjustable
wrench. Undo completely when
they are loose enough to work by
hand. The pipes will come apart
when the couplings disconnect.

7. Loosen and remove all the bolts
that anchor the pump to the
pump stand using the adjustable
wrench. Remove the pump from
the pump stand of the existing

tank. (Fig. 4) If there is not enough
slack in the wiring to let the pump
rest on the floor, either rest it
on a stool or the new pump, or
disconnect the wiring. Don’t let it
hang in the air.

8. Remove the plastic cap on the air
valve on top of the tank. Check
the air charge in the new tank
using the tire pressure gauge.

Adjust the pre-charge pressure

in the tank to be 1-2 psi below
the pressure switch pump cut-in
setting. First look inside the cap to
the pressure switch to determine
the pump cut-in setting. It should
say “20/40” or “30/50” or the
like. The pressure in the tank
should be adjusted to be 2 psi
below the lower pressure of
these two numbers. That is, the
tank pressure should be set at
about 18 psi if the cap indicates a
setting of 20/40, or set at about
28 if the cap indicates a setting
of 30/50.

If this charge is too high, release

some air by pressing down on
the pin inside the air valve. If the
charge is too low, pump it up
using a bicycle tire pump or air
compressor.

Alternatively, you can adjust

the pressure switch to match
the pressure in the tank. See
instructions on the inside of the
pressure switch cap for how to
do this.

9. Place the pump on the pump
stand of the new tank. (Fig. 5)

Do not insert the bolts yet. (You
will need to move the pump
around to pipe it to the existing
pipes.)

10. Install the new tank.

a. Remove the inlet pipe to the

existing tank. (Fig. 6) Either
re-use the existing inlet assembly,
or purchase a tank installation kit,
which should include: a 3/4” x 4”
or so pipe nipple; a 3/4” fpt x 3/4”
fpt x 3/4” fpt pipe tee; and a 3/4”
fpt standard drain/boiler drain
valve.

b. Apply Teflon® tape to the

threaded male end of this inlet
pipe which inserts into the tank.

c. Insert this inlet pipe into the

female pipe threaded opening at
the end of the new tank. Tighten
hand tight. Then wrench tight
using the pipe wrench and the

12” adjustable wrench. (Fig. 7-8)
Make sure that the pipe to the
supply line ends up in a vertical
position pointing up. Tighten
slowly to make sure you do not

over tighten. (Fig. 8) Do not
loosen the pipe once tightened. If
you do, it is more likely to leak.

d. Move the existing tank out of the

way. Discard.

e. Move the new tank into position

with the inlet assembly attached.

f. If the two tanks are the same size,

then the piping will match up.

If the two tanks are different sizes,

then the piping for the new tank
probably will not match the old. In
this case, adjust the piping to fit.
If pipes are mismatched by only
a small amount, you can force the
pipes to fit or use nipples that are
longer or shorter to make ends
meet.

g. Match up the union couplings.

If you do have a Pressure Relief

Valve in the system, go on to
Step 12.

If you do not:
a. Remove the boiler drain from the

inlet valve now on the tank. Make
the pipe tee/nipple assembly.
Wrap Teflon® tape around one
of the male threaded ends of
the nipple. Insert it in one of the
female threaded openings in the
3/4” fpt x 3/4” fpt x 3/4” fpt
pipe tee. Tighten hand tight, then
wrench tight.

b. Install the pipe tee / nipple

assembly. (Fig. 13) Apply Teflon®
tape to the male thread at the
other end of the nipple (which is
now half inside the pipe tee). Insert
the pipe tee / nipple assembly
in the female threaded opening
on the tank inlet assembly from
which you removed the boiler
drain. Tighten hand tight, then
wrench tight.

an adequate drain must be
installed if leaking and flooding
could cause property damage to
the area adjacent to the appliance
or to lower floors of the structure.

c. Install the pressure relief valve.

Apply Teflon® tape to the male
threaded end of the valve.

Insert the pressure relief valve in

the female threaded opening on
the side of the pipe tee. Tighten
hand tight, then wrench tight.

(Fig. 14)

d. Insert the standard drain in the

female threaded opening of the end
of the pipe pee/nipple/pressure
relief valve assembly. Tighten hand

tight, then wrench tight. (Fig. 15)

13. Watch for any leaks in the system.
Turn the power back on. The
pump will start and fill the tank.
Turn on a faucet as far above the
pump as possible. This will let air
leave the system as it fills with
water. As soon as water comes
out of the faucet you just turned
on, turn it off. The pump will
now build pressure in the system
until that pressure reaches the
pump cut-out setting. If you
see a leak, turn off the power
immediately and tighten or re-do

the connection that is leaking. It should take 30 seconds to 1
minute for the pump to prime.

If the pump does not fill the tank, turn the system off and
check the manufacturer’s instructions for priming the pump.
Turn on a faucet nearby to see that the system is operating
properly.
