TROUBLESHOOTING

If the device and pump do not seem to be operating correctly
together by starting and stopping with water usage, first check
that the technical features of the flow controller and the pump
are compatible. Use the table and figures in this manual to
confirm compatibility.
For the Inline CTL flow control to properly operate the pump system,
water must pass through the device every time water is needed. The
water supply to the device can be a municipal / utility water main
line, a stored water volume above the pump, or a suction lift source
like a well where the pump is above the water source or submerged
within. This allows the device to be used with both surface mounted
or submersible well pump product designs. For suction lift or
submersible water system applications the Inline pump flow control's
have a built in check valve, but proper suction line check valve or foot
valve placements are needed to ensure the system holds water for
priming and operation.
Waterhammer or hydraulic vibration: Some installations with high
water flow rates or excessive water turbulence could experience
waterhammer or hydraulic shock vibrations. To mitigate these effects
an additional 2 gallon (or larger as desired) pressurized bladder
expansion tank can be installed in the discharge plumbing upstream
from the pump/control device. The air charge in this bladder tank
should be set to match the system working pressure.
Problem
Bad electrical connection.
Tripped electrical circuit breaker/fuse.
Pump obstructed.
Pump fails to start or restart
No water flow.
Control unit not installed vertically in proper orientation.
Minimum flow of 0.15 gpm not sustained.
Pump works intermittently
Plumbing or check valve leak
System flow continues above 0.15 gpm.
Device contains debris preventing switch closure.
Pump will not shut off
Control unit not installed vertically in proper orientation.
Plumbing or check valve leak

Water System Plumbing Leaks: All water leaks within the plumbing system
should be corrected for optimal performance of the system. If water leaks
cannot be corrected or mitigated, to prevent frequent pump starts, an
additional pressurized bladder expansion tank should be installed with an
internal water draw down capacity capable of supporting the pump start
frequency desired. The air pressure charge of this tank should be set to
roughly the same as the systems working pressure.
Waterwell systems with high static water levels or Systems with high
incoming pressure: Some waterwell applications will be such that
the water level in the well will change dramatically over time or with
use. If that is the case there is an opportunity for the submersible
well pump to create high pressure when the water table is high (also
called a high static water level), but then the pressure will decrease
as the water level dynamically drops in the well. In this case the Inline
Control devices are rated to operate in high pressure installations of
up to 174 PSI. If the water supply pump produces greater than 174
PSI additional pressure mitigation equipment, such as a pressure
regualting valve, may need to be installed on the inlet plumbing line
feeding the Inline Control device to prevent system damage.
Troubleshooting
Probable Causes Corrective Action
Check the electrical connections.
Check electrical circuit breaker panel.
Check pump and suction line for debris.
Check plumbing and water supply.
Correct installation so that the control device is vertical, with all writing on
the product label in the proper upright position.
Increase water use.
Repair or replace faulty plumbing/check valve
Confirm that there is no water demand.
Check plumbing system for leak.
Clear debris from unit or plumbing.
Correct installation so that the control device is vertical, with all writing on
the product label in the proper upright position.
Repair or replace faulty plumbing/check valve
