NOTE:
The minimum working pressure refers to the pressure required to operate the valve. Higher pressure
may be required for an effective flush, depending on the bowl and sparge outlet design.
NOTE:
When using the Direct Flush valve from a mains water supply, the pressure may be higher than is
suitable for the design of the sparge or bowl which may cause splashing to occur. In such cases a
pressure reducing valve on the supply may be required to reduce the pressure as necessary.
