ET3-M SMART DEMAND URINAL FLUSH VALVE TROUBLESHOOTING YOUR INSTALLATION
Initial Checks
•
•
•
•
•
•
CHECK WATER SUPPLY;
UNPLUG ALL CABLES, (TAKING CARE TO UNSCREW ALL CONNECTIONS FULLY PRIOR TO
DISCONNECTION) LEAVE UNPLUGGED FOR 5 MINUTES (THIS GIVES THE ELECTRONICS A CHANCE TO
RESET) BEFORE RECONNECTING EVERYTHING CAREFULLY IN THE CORRECT ORDER (SEE DIAGRAM
BELOW) WARNING - ELECTRONICS WILL BE DAMAGED IF CONNECTED OR DISCONNECTED
INCORRECTLY;
ENSURE SCREWED COLLAR CONNECTIONS ARE TIGHT (DO NOT OVERTIGHTEN);
IF URINAL HAS BEEN OPERATING CORRECTLY FOR SOME TIME AND HAS SUDDENLY STOPPED – LIKELY
CAUSE IS NO POWER. TO CONFIRM - CHANGE BATTERIES, UNIT SHOULD FLUSH. CHECK MAINS POWER
SUPPLY/HOTPOINT AS FLUSH VALVE MUST BE MAINS POWERED WITH BATTERY BACK-UP; IT IS NOT
DESIGNED TO RUN ON BATTERY ONLY;
IF NEW INSTALLATION - CHECK THAT IT HAS BEEN INSTALLED CORRECTLY, IN ACCORDANCE WITH THE
INSTALLATION MANUAL.
^IN-CEILING INSTALLATIONS – FLUSH VALVE MUST BE INSTALLED VERTICALLY. COPPER PIPE MUST BE
USED BETWEEN SOLENOID AND URINAL; IT MUST BE VERTICAL AND STRAIGHT. CHECK THAT NO FLEXIHOSE HAD BEEN USED AND THERE ARE NO BENDS/KINKS OR HORIZONTAL SECTIONS OF PIPEWORK.
INCORRECT INSTALLATION CAN SLOW/IMPEDE THE FLOW OF WATER FROM THE SOLENOID TO THE
URINAL AND OVER THE SENSOR ACTIVATION ZONE, CAUSING RE-FLUSH ONCE CONFIRMATION TIME IS
COMPLETE. IF PROBLEMS PERSIST – CONSIDER INSTALLATION OF AIR-BREAK VALVE (RECOMMENDED).

STANDARD IN-WALL INSTALLATION METHOD - COMPONANT TESTING
If your in-wall installation is correct, but your flush valve is still not functioning correctly,
carrying out the following tests will determine exactly which component is causing the issue.
All components can be replaced easily and quickly.
NB: When testing – note confirmation times of product and wait 60 seconds between tests.
Rapid repeated testing will cause product to enter Stadium Mode, resulting in intermittent
flushing.
Connection Test - this will confirm if controller is working correctly. It will confirm that there
is power and that the connections are correct - Unplug sensor cable and rub thumb over the
4 metal pins. The red light on the controller will start to flash. Stop rubbing the pins when the
red light stops flashing (up to 20 seconds). The solenoid will be activated, you should hear it
clicking, and the urinal will flush.
Outcome of Connection Testing:
•
•
•
IF NO LIGHTS ON CONTROLLER – CHECK POWER SUPPLY, REPLACE BATTERIES, CHECK CONNECTIONS
ARE CORRECT AND FULLY TIGHTENED (SEE DIAGRAM ON PAGE 1). REPEAT TEST. IF STILL NO LIGHTS,
YOU MAY NEED TO REPLACE THE CONTROLLER;
IF CONTROLLER LIGHTS UP BUT THE UNIT DOES NOT FUNCTION CORRECTLY o WATER CONSTANTLY RUNNING ON CAN MEAN NOT ENOUGH POWER TO SOLENOID ; CHECK
POWER SUPPLY, REPLACE BATTERIES, CHECK ALL CONNECTIONS ARE CORRECT AND FULLY
TIGHTENED (SEE DIAGRAM ON PAGE 1);
o OR THAT DEBRIS FROM WATER CONTAMINATION IS PREVENTING THE SOLENOID FROM
CLOSING. CLEAN SOLENOID, FLUSH PIPEWORK THOROUGHLY AND CHECK WATER PRESSURE
DOES NOT/HAS NOT EXCEEDED 500KPA THEN RE-TEST. IF ISSUE PERSISTS, YOU MAY NEED
TO REPLACE SOLENOID*;
IF CONTROLLER ACTIVATES AND URINAL FLUSHES CORRECTLY – RECONNECT THE SENSOR CABLE TO
REST OF UNIT, WAIT FOR 60 SECONDS BEFORE CARRYING SENSOR TEST (SEE OVER PAGE);
2
Sensor Test – This will confirm that the sensor has been installed correctly. Make sure silicone
is dry before performing flush test - Pour water slowly over the surface of the urinal (must
run over sensor location). If the red light on the controller is flashing, when you stop pouring
water the red light will stay on - there will be a delay, but the urinal should flush.
Outcome of Sensor Testing:
•
•
IF NO LIGHTS ON CONTROLLER OR UNIT DOES NOT FLUSH, CHECK THAT SENSOR HAS BEEN INSTALLED
CORRECTLY I.E. THAT THE ‘CERAMIC SIDE’ IS AGAINST THE URINAL CERAMIC AND THAT THE SILICONE
HAS NOT SPREAD TO SENSING SURFACE. (SEE DRAWING BELOW);
IF SENSOR INSTALLATION IS CORRECT - CHECK SENSOR CABLE CONNECTION IS FULLY TIGHTENED.
REPEAT TEST. IF UNIT STILL DOES NOT FLUSH, YOU MAY NEED TO REPLACE THE SENSOR.
^ALTERNATIVE INSTALLATION METHOD - VALVE MOUNTED IN-CEILING
The requirements of this method of installation should have been discussed prior to
purchase. Enviro-Tech recommends that an air-break valve be installed and the use of a
single straight copper pipe between the solenoid outlet and the urinal, no horizontal
sections or flexi-pipe. (See installation manual for further details). If you are experiencing
problems with activation, ensure that your installation is correct.
This product is pre-set to deliver 0.8l per flush at 350kPA, any adjustments to flow should be
made on the flow valve, next to the inlet on the solenoid. Do not attempt to make any
adjustments to the controller.
Function of individual components can tested by following the component testing
instructions for the in-wall installation method, detailed on Page 2.
Next Steps:
If testing has confirmed that a component is not functioning, call us or e-mail us to discuss
(see our contact info over page). If you have multiple flush valves on site – see the Advanced
Troubleshooting Section on Page 4.

If you would like a little extra guidance or have any questions, then do get in touch. We will
ask for photos of the installation, your photos must at least show - the solenoid, controller,
all connections and outlet pipework to the urinal. Photos can be e-mailed to the address
above.
ADVANCED TROUBLESHOOTING
If you believe that you have a faulty part and you have more than one urinal flush valve on
site, it is easy to confirm component fault by swapping out parts with a second urinal that you
know to be working. Start with the controller, if the same issue occurs with the replacement
controller – look again at your installation to confirm it is correct. Other parts can also be
swapped out to confirm exactly which component is causing the issue.
NEW INSATLLATIONS ONLY:
IF •
•
•
•
YOUR PRE-INSTALLATION COMPONENT CHECK (SEE MANUAL) AND ALL THE TESTING DETAILED IN THIS
TROUBLESHOOTING GUIDE HAS CONFIRMED THAT ALL COMPONENTS ARE FUNCTIONING CORRECTLY;
YOU HAVE CONFIRMED THAT WATER IS CORRECTLY CONNECTED TO THE URINAL;
YOU HAVE CONFIRMED THAT THE SENSOR IS ATTACHED TO THE URINAL AS PER THE INSTALLATION
MANUAL;
THE URINAL FLUSHES WHEN YOU HAVE PERFORMED THE THUMB TEST BUT NOT WHEN ALL COMPONENTS
ARE CORRECTLY INSTALLED AND ATTACHED TO THE URINAL CERAMIC;
THIS MEANS –
The Urinal Ceramic is thicker than the standard product set-up allows for. This is unusual but
can be resolved. We provide the following guidance to assist BUT we strongly recommend
that you speak to us first. Delicate electronics can be damaged without correct care and would
not be covered by your product warranty.
ADJUSTMENT
CONTROLLER EXTERNAL VIEW
Carefully remove front cover by inserting small flat edge screwdriver into hole on the side
of the controller.
4
CONTROLLER INTERNAL VIEW
There is a protective layer of sealant over all the internal components. Taking care, break
the sealant covering the adjustment screw – see drawing below. Use a small cross head
screwdriver and a gentle ¼ turn clockwise to increase the sensor distance. NB. Excessive
force will cause the grub screw to snap.
PRODUCT WARRANTY
Your Flush valve has a 12-month parts only warranty.* In the unlikely event of component
failure and once fault is confirmed, Enviro-Tech will send the replacement part for fitting by
your installer/plumber. Please note that replacing a part will rectify any genuine product fault.
If the replacement part does not fix the issue - you will need to re-check the installation and
consider what external factors are causing the problem.
*Damage to solenoid caused by debris due to inadequately flushed lines or excessive water pressure, is not
covered by the product warranty. Damage to components caused by incorrect connections is also not covered
by the warranty. For full warranty conditions, see the Warranty page of our websites.
