    What is the applicable water pressure of this water purifier? Can I use this water purifier at low water pressure?

    Published on 2019-08-28
    The required inlet pressure of this water purifier is between 2 bar (0.2 MPa) and 4 bar (0.4 MPa).

    If the input water pressure in your house is less than 2 bar (0.2 MPa), you can still use the water purifier, but the filtered water flow may be minimal or the water purifier may be damaged, so we recommend that you should install booster pump to use.

    The information on this page applies to the following models: WP4111/90 , WP4141/90 , WP4161/90 .
