After a sudden break in the water pipe, YDROSTOP immediately stops the water supply. In the event of systematic water loss (small leaks, open taps...), YDROSTOP shuts off the water supply after a preset time.

  1. Shut off the water supply immediately in the event of a pipe break
  2. Shut off the water supply in case of a leak in the pipe, according to the preset time
  3. Prevents unnecessary water consumption

Did you know that a short weekend is enough to let 80,000 liters of water (or the contents of a private swimming pool) flow through your house in the event of a pipe break?

The operation of YDROSTOP is based on the pressure difference that passes over the unit.

  • If the YDROSTOP detects too great a pressure difference, YDROSTOP immediately shuts off the water supply.
  • With normal water consumption, there is a small pressure difference and the timer mechanism is activated.
  • In case of prolonged water consumption and exceeding the set time (15 min. to 120 min.), YDROSTOP shuts off the water supply.
  • To reopen/reset YDROSTOP, close the open tap, repair the leak or crack, open the tap again after repairing the leak or crack.
  • Pressure can then build up again in the pipeline, as soon as the inlet and outlet pressures of YDROSTOP are equal, the YDROSTOP can reopen and function again
