Step IV: Install the new tank.

1. Install the new tank. Place it where the old tank was or stand

it in a position so that you can make the pipes meet the

tank cross. If necessary, place the tank on garden bricks or

cinder blocks to make sure that it stands at the right height.

Connect the tank to the pump

supply lines using piping to ﬁt.

Follow all applicable local and

state codes and ordinances. Note:

Do not place the tank where it or

the controls on it will freeze. This

can damage the system.

2. Screw the pipe unions hand tight

ﬁrst, then tighten wrench tight

using the pipe wrench.

3. Re-install the wires in the pressure

switch. Attach the leads to the

connections as you marked them.

(Fig. 16)

4. Replace the cover to the pressure

switch. Check to make sure that

the standard drain/boiler drain

valve is closed. (Fig. 17)

5. Remove the plastic cap on the air

valve on top of the tank. Check

the air charge in the tank using the

tire pressure gauge.

Adjust the precharge pressure in

the tank to be 1 to 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 of these two numbers. That

is, the tank pressure should be set

at about 18 psi if the cap indicates

a cut-in setting of 20/40, or set

at about 28 if the cap indicates a

setting of 30/50.

The table, "Exhibit A", indicates

the air charge in the tank when the

tank is shipped from the factory.

Release or add air to adjust the

pressure properly. If the 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 cap to the pressure switch

for how to do this.

Step V: Turn the power back on. The pump

will fill the tank. The system is now ready

to use.

1. Open the gate valve to let water

ﬂow back into the tank. This is the

valve that you closed in Step I.3

{See Step I.3 for a photo of the

gate valve} (Fig. 18)

2. Turn on the faucet that is the

highest in the house and farthest

from the tank. This will allow air to

exit the system as water enters.

3. Turn the power back on. The pump

will start and ﬁll the tank. Watch

for any leaks in the system. If you

do see a leak, turn the power off

immediately and repair the leak at

the joint. It should take 30 seconds

to a minute for the pump to prime

if it is a jet pump. If the pump does

not ﬁll the tank and shut off in one

minute or so, check the pressure

gauge. If the gauge is moving,

let the pump continue to run. If

the gauge is not moving, turn the

power off. This means that the

pressure switch is either installed

improperly or is defective. Check

the manufacturer’s instructions.

Replace it if necessary and test

the system again to see that it is

installed properly.

4. Turn a faucet on nearby to

check that the system is working

correctly.
