  • The filter of the timer and hose are both installed correctly.
  • The faucet or hose has a 3/4" NH thread.
  • Water pressure is within the specified range (8-120PSI / 0.5-8Bar).

TIMER VALVE WON'T TURN ON/OFF. RESET THE VALVE:

  1. Attach the timer to a faucet and open the faucet to maximum.
  2. Manually turn the timer on for more than 5 seconds, then turn it off.
  3. Repeat this process more than 5 times until water flows properly.

TIMER DECREASE WATER PRESSURE:

This timer uses a solenoid valve, which technically decreases water pressure. Restmo also offers ball-valve timers that do not decrease water pressure. If unsatisfied with the reduced water pressure, contact Restmo for details on ball-valve timers.
