What You’ll Need
Before You Start
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.

IMPORTANT GENERAL SAFETY INFORMATION - ADDITIONAL SPECIFIC
SAFETY ALERTS APPEAR IN THE FOLLOWING INSTRUCTIONS.
Failure to utilize a properly sized well tank will result
in excessive strain on the pump and may ultimately
lead to product failure, leaking or flooding or property damage.
For your safety, the information in this manual
must be followed to minimize the rise of electric
shock, property damage or personal injury. Properly ground to
conform with all governing codes and ordinances.
1. If you are installing an entirely new well system, follow Steps II,
III, IV and V. Skip Step I, since you are not removing an existing
tank. However, make sure that the power is turned off before
you hook up the pressure switch to the household wiring. If
you are in any doubt about working with electricity, call a
licensed electrician.
2. If you are replacing a plain steel tank with this Water Worker
diaphragm tank:
a. A diaphragm tank is pressurized with air at the factory (at a
pressure close to that of a car tire). For this reason, it will be
smaller than the plain steel tank, even though both tanks deliver
the same amounts of pressurized water. Because of this, you may
have to adjust the piping to reach the new connections.
b. Install a pressure relief valve at the tank connection to ensure the
safety of the system.
c. If you have a deep well submersible pump, remove all the air
charging devices from the well system (snifter valves, bleeder
orifices, vacuum lines and connection). Then plug the holes
where these devices were located (see your owner’s manual
for location of these devices). These devices are not needed for
pre-charged tanks, and if they are not removed and the holes
plugged, air can get into the well system, cause surges, damage
the system, and impair performance.
d. If you have a jet pump, remove the fittings and plug the
openings where the vacuum or air lines and air volume controls
connect to the pump or piping. If not removed and plugged,
they can allow air into the pipes which can damage the well
system and impair performance.
e. In addition to the above, follow Steps I through V.
3. If you are replacing a diaphragm or bladder style tank with this
Water Worker diaphragm tank:
a. If the two tanks are the same size, follow Steps I through V.
b. If they are different sizes, follow Steps I through V and also adjust
the piping as necessary to accommodate the new size.
4. It is good practice to replace the pressure gauge and the
pressure switch whenever you replace an old tank. Of course,
you can re-use the tank cross assembly if you are replacing a
diaphragm tank with another diaphragm tank (including the tank
cross, pressure gauge, pressure switch, pressure relief valve, pipe
nipple and drain).
a. If you do re-use a tank cross assembly, skip Step II. In this case,
make sure that the tank is installed as closely as possible to the
pressure switch. This will make the system operate as efficiently
as possible.
b. If you replace the tank cross assembly with new parts when
you install the new tank, complete all of the steps in these
instructions, Steps I through V.
RELIEF VALVE REQUIRED.
A relief valve should
be installed which is set to open at excessive
pressures (75 psig or more). This will protect the well tank and other
system components should the pressure switch malfunction and
fail to shut the pump off. The relief valve should be installed at the
connection of the well tank to the system piping and have a discharge
equal to the pump’s capacity at 75 psig. At least once every 3 years
or if discharge is present, a licensed contractor should inspect the
temperature and pressure relief valve and replace if corrosion is
evident or the valve does not function. FAILURE TO INSPECT THIS
VALVE AS DIRECTED COULD RESULT IN UNSAFE TEMPERATURE OR
PRESSURE BUILD-UP WHICH CAN RESULT IN PRODUCT FAILURE,
SERIOUS INJURY OR DEATH AND/OR SEVERE PROPERTY DAMAGE
AND VOID THE PRODUCT WARRANTY.
5. Always make sure that you equip your well system with an
appropriate pressure relief valve. Whether you are re-using a
tank cross assembly or assembling a new one, check to make
sure that the assembly includes a pressure relief valve that is
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 system.
