Cause
Batteries not installed
correctly.
Batteries are depleted.
Damage or corrosion of the
battery terminals.
High pressures may lead to
an increase in noise.
Damaged renewable seat.
Partially closed inlet stop.
Inlet stop may be open too
much.
Inlet stop may not be open
enough.
Supply line may be blocked
or under sized.
Not enough water pressure
and/or flow rate.
The Regulating Screw may
require adjustment.
Bypass slot partially or
completely obstructed.

obstructed or damaged.
MMO button not working
correctly.
Solenoid not connected to
controller or damaged.

Check that the four "AA" Alkaline batteries are positioned properly in the
battery holder. Use the +/- signs on the batteries and the +/- signs on the
battery holder for correct positioning.
Replace with four new "AA" Alkaline batteries (see "Battery Replacement
(see Figure 15)" on
page
19).
Check for damage or corrosion of the battery terminals in the battery holder.
Replace battery holder and batteries if necessary.
While the TECK Flushometer will operate up to 125 PSI, the preferred
operating range is between 35 to 65 PSI.
1. Lower the flow rate by reducing the flowing pressure upstream of the
flushometer by adjusting the screw stop. Close the stop completely and
re-open 1 turn. Then adjust the screw to stop the noise.
2. Other options include installing a Pressure Reducing Valve (PRV), or ball
valve upstream to the flushometer.
On flushometers that have been installed for a number of years, check the
renewable seat for wear and replace if necessary.
Open inlet stop
Close the stop completely and re-open 1 turn. Adjust the stop to meet the
required flush volume specification.
Operation of flushometer with inlet stop BELOW ONE TURN
W
OPEN may cause EXCESSIVE NOISE. The lowest open setting for the
inlet stop may vary depending on the installation.
OPEN inlet stop fully.
CHECK supply line for size or obstruction, partially closed gate or other
supply line valve, corroded or under size water piping.
CHECK water pressure and flow rate.
Water supply may be restricted upstream. Open any devices being used to
restrict pressure and/or flow rate to the flushometer (PRV, ball valves, supply
stops).
Adjust by slowly turning the regulating screw LEFT (counter-clockwise)
(except on models that have a fixed volume). See section "Flush Volume
Adjustment/Réglage Du Volume De Chasse" on
adjusting.
1. Clean bypass slot.
2. Replace cap/solenoid & regulating screw assembly if required.
See section "Cap/Solenoid & Regulating Screw Assembly Maintenance
(see Figure 18)" on
page 21
for instructions.
1. Check for damage and alignment of the diaphragm.
2. Replace Diaphragm/Guide Assembly if required.
See section "Diaphragm/Guide Assembly and Seat Maintenance (see
Figure 19)" on
page 22
for instructions.
1. Clean MMO button assembly.
2. Replace MMO button assembly if required.
See section "MMO Button Maintenance (see Figure 20)" on
instructions.
1. Verify wiring is connected correctly. The solenoid is connected black to
black, red to red with the electronic compartment.
2. Replace cap/solenoid & regulating screw assembly if required.
See section "Cap/Solenoid & Regulating Screw Assembly Maintenance
(see Figure 18)" on
page 21
for instructions.
Verify sensing range of the flushometer and adjust if required.
See section "Setup Mode Adjustments (see Figures 10-11) / Réglages du
mode d'installation (voir la Figures 10-11)" on
See section "Inadvertent Flushing" on
angle adjustment.
