Battery model timer with solenoid valve — $240

Not recommended for use where rough treatment or vandalism is likely.

  • The shower is terminated after the chosen time and that is followed by a “discouraging” waiting period.
  • Shower and waiting times are chosen by the owner up to a maximum of 15 and 30 minutes respectively.
  • Power is supplied by a battery of six AA cells (not included). Good quality alkaline battery is recommended.


Shower and waiting times are chosen by the owner and also the beeper can be disabled, using mini switches mounted on the electronic circuit board inside the control box. These settings cannot be changed except by removing the shower and the box from the wall. The box can be secured to the wall with the screw provided and a plastic seal must be broken to remove that screw.


Similar to the other retrofit models but there is no need to run a power lead in through the wall because the battery is contained in the box.


Push the Start button and the shower will start under the control of hot and cold taps. The progress or Status is indicated by a “traffic” light emitting diode (LED). Every 10 seconds, it flashes green but changes to amber when one minute remains and then red for each of the final 10 seconds. The LED is supported by an optional beeper which will sound twice as a 2 minute warning, once at 1 minute, at 10 seconds and each of the last 5 seconds. The “Finish” light will also flash red for the final 5 seconds. After the shower is terminated, the blue “Wait” light will flash every 10 seconds until waiting time is complete. The “Battery low” light will flash red when it is time to replace the battery. Soon after that, the solenoid valve will open permanently allowing normal, unrestricted showers and the “Battery low” light will continue to flash intermittently.

Note: The shower head is not supplied. You can usually use your existing one with the shower timer or save more with a water saving shower head!
