DANGER! EXPLOSION HAZARD. WHEN THE
WELL TANK HAS BEEN IN SERVICE AND A
CHANGE TO A HIGHER PRE-CHARGE PRESSURE IS NECESSARY
DUE TO A REQUIRED CHANGE IN THE PRESSURE SWITCH
SETTING, FAILURE TO FOLLOW INSTRUCTIONS BELOW CAN
CAUSE A RUPTURE OR EXPLOSION, POSSIBLY CAUSING SERIOUS
OR FATAL PERSONAL INJURY, AND/OR PROPERTY DAMAGE.
 •DO NOT ADJUST OR ADD PRESSURE IF THERE HAS BEEN A
LOSS OF AIR.
 • DO NOT ADJUST THE PRE-CHARGE PRESSURE IF THERE IS
VISIBLE EXTERIOR CORROSION.
 •DO NOT ADJUST THE PRE-CHARGE PRESSURE IF THERE
HAS BEEN A REDUCTION OF THE PUMP CYCLE TIME OR
THE PRE-CHARGE PRESSURE COMPARED TO ITS INITIAL
SETTING. THIS IS BECAUSE REDUCTION IN PUMP CYCLE TIME
CAN RESULT FROM LOSS OF TANK AIR PRESSURE WHICH IN
TURN CAN MEAN THERE MAY BE INTERNAL CORROSION AND
ANY RE-PRESSURIZATION OR ADDITIONAL PRESSURE COULD
RESULT IN RUPTURE OR EXPLOSION.
MAXIMUM WORKING PRESSURE. Every Well-X-Trol
is tested to 150 psig, the maximum working pressure
for the Well-X-Trol line. Should pressures exceed 150 psig, proper
selection and sizing of an ASME Well-X-Trol should be made.
RELIEF VALVE REQUIRED. A relief valve should
be installed which is set to open at excessive
pressures (125 psig or more). This will protect the Well-X-Trol 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-X-Trol to the system piping and have a discharge equal to the
pump’s capacity at 125 psig.
AS IN ALL PLUMBING PRODUCTS AND WATER
STORAGE VESSELS, BACTERIA CAN GROW IN
YOUR WELL TANK, ESPECIALLY DURING TIMES OF NON-USE.
CONSULT YOUR LOCAL PLUMBING OFFICIAL REGARDING ANY
STEPS YOU MAY WISH TO TAKE TO SAFELY DISINFECT YOUR
HOME’S PLUMBING SYSTEM.
A water test must be taken before installation of any
water treatment equipment.
DANGER! EXPLOSION HAZARD. IF YOU
ADJUST THE PRE-CHARGE PRESSURE OR ADD
PRESSURE TO A TANK THAT IS CORRODED OR DAMAGED OR
WITH DIMINISHED INTEGRITY, THE TANK CAN BURST OR EXPLODE,
POSSIBLY CAUSING SERIOUS OR FATAL PERSONAL INJURY AND/
OR PROPERTY DAMAGE.
 •ONLY ADJUST THE PRE-CHARGE AS DESCRIBED IN THIS
MANUAL WHEN THE TANK IS NEW OR WHEN THE INTEGRITY OF
THE TANK AND LACK OF INTERNAL OR EXTERNAL CORROSION
IS CONFIRMED.
 • ONLY QUALIFIED PROFESSIONALS SHOULD CHECK, ADJUST
OR RE-CHARGE THE PRE-CHARGE OF TANKS.
For your safety, the information 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.
Do not install in direct sunlight. Excessive sun heat
may cause distortion or other damage to non-
metallic parts.
Use only lead-free solder and flux for all sweat-
solder connections, as required by state and
federal codes.
ELECTROCUTION AND EXPLOSION HAZARD.
Before work is performed on the tank, turn off the
power to the pump and release all water pressure in the tank and
pumping system.

How a Well Tank Works
1. As the pump fills the tank with water, the air above the
diaphragm is compressed. This increases the pressure in the
tank and causes the pressure switch to turn off the pump.
2. When water is used, it is drawn from the tank and the pressure
inside the tank decreases. The reduced pressure starts the
pump and refills the tank.
The amount of water delivered between pump cycles is called
drawdown. The larger the well tank, the greater the drawdown
capacity, the less the pump needs to run. This saves energy and
money, and extends pump life. Larger tank sizes also increase the
water storage volume to provide more consistent water pressure.

Installation of In-Line Turbulator™
The In-Line Turbulator water circulation device is designed to
circulate the water stored in your diaphragm well tank.
1. Inspect the In-Line Turbulator for any damage that may
have occurred during shipping. Insert the In-Line Turbulator
(Diagram 1) into the system connection of the expansion tank.
The Turbulator can only be inserted with the butt end out as
the locking tabs prevent it from being installed backwards.
2. Palm press the In-Line Turbulator (Diagram 2) until the unit
locking tabs butt up against the system connection.
3. Your diaphragm well tank is now ready to be installed
(Diagram 3).

Pre Installation
The surface on which the Well-X-Trol is installed should be
capable of supporting its operating weight (including the weight
of water). The Well-X-Trol should be installed as close as
possible to the pressure switch. This will reduce the adverse
effects of added friction loss and differences in elevation
between Well-X-Trol and/or water supply main and switch.
Adjacent to pump: This is the location chosen most often. The
Well-X-Trol tank can be used whether pumps are above or
below the surface. In either case, it protects the pump by
reducing surge, dampening pressure spikes, offering a point of
pressure control, and providing minimum run time. This location
also permits all equipment to be placed in an area that’s both
serviceable and secure.
At the end of long pipe runs: The Well-X-Trol tank can be
positioned at the end of a long run of pipe so it can provide rapid
system response and adequate protection. When this location is
chosen, the pressure switch should either be relocated with the
Well-X-Trol tank or the setting should be adjusted to compensate
for any line pressure drop.
DO NOT LOCATE IN AN AREA WHERE
LEAKAGE OF THE TANK OR CONNECTIONS
COULD CAUSE PROPERTY DAMAGE TO THE AREA ADJACENT TO
THE APPLIANCE OR TO LOWER FLOORS.
1. Remove protective air valve cap.
2. Check pre-charge pressure.
3. Release or add air as necessary to set the pre-charge
pressure 2 psig below the pressure switch pump cut-in
setting. (Example, 38 psig precharge for a 40/60 pressure.)
4. Replace protective air valve cap.

Underground Models:
All Well-X-Trol Underground Tanks are designed for direct
burial and must be installed in the vertical position only. To
eliminate danger of freezing, tank should be buried below the
frost line.
The following steps should be taken when installing a Well-X-Trol
Underground Tank:
1. Make sure that the tank will be buried below the frost line and
above the water table.
2. Remove plastic bag and check tank precharge. Factory
precharge is 38 psig. Replace air stem cap securely. Follow
adjusting precharge procedure.
3. Important: Install tank on firm rock-free earth.
4. The water lines from the pump to the tank and switch location
should be the same size to prevent switch cycling.
5. Check the system for performance and inspect for leaks.
6. Important: Backfill hole with sand. Firmly tamp fill to prevent
settling. Failure to do so will shorten tank life.
7. Fill out pressure tank location sticker and affix to power panel
or other visible surface so tank can be easily located at a
later time.
