Most frequent questions

  • Can the Quooker be connected to softened water? Installation

    You may connect the Quooker to softened water as long as the water supplied to the Quooker meets the below criteria:

    Water Supplied to the Quooker must be potable within the limits of the Ireland drinking water regulations. Your supplier would be able to confirm that.

    Minimum water pressure of 2 bar (ideally 2.5 – 3 bar)

    Ph value of the water of between 6.5 and 9.5 with no excessive salt.

    Alternatively, you can fit the Quooker to the hard water supply and either periodically service the Quooker system or fit our Quooker Scale Control to it.

    For further information on maintaining your Quooker and dealing with limescale, please see the relevant FAQ "What maintenance does a Quooker require?" under the "Maintenance" section.
  • The inlet combination valve (pressure release valve) is releasing water. Troubleshooting

    It is normal for the inlet combination valve to release drips of water while the tank is heating water. This is expansion water released from the tank to regulate the pressure inside the tank.

    If the Quooker has been fitted recently and the valve is releasing a continuous flow or spurts of water, please check the incoming water pressure. The ideal incoming water pressure for the Quooker is 2-3 bar. If the pressure is too high, the valve will release more water in order to keep the pressure inside the tank at a safe level. A pressure reducing valve can be fitted to reduce the pressure to 2-3 bar.

    If the Quooker has been fitted for a while and the valve has recently started running continuously (rather than dripping), some debris or scale may be caught inside the valve. Please try flushing the valve through as follows:

    Switch off the tank by pressing the Q-shaped button on top. Run the boiling tap for a few minutes until the water runs cold. Place a container under the valve and turn the large red cap (10 bar valve) or large grey cap (8 bar valve) anti-clockwise until you hear a click. Water will be released from the valve in a quick gush. Repeat this several times before switching the Quooker back on.

    If this does not resolve the issue, please contact our service department via or 0207 9233355 (select option 3 for Service). Please have your Quooker's serial number ready – it is located at the side of the tank near the top.
