Make sure that the valve is level.
Install the valve so that the outside surface of the
finished wall falls between the "min" and "max"
markings.
Flush the hot and cold supplies
The hot supply will flush through the
bottom outlet, and the cold supply will
flush through the top outlet – see the
arrows on the flushing block.
If one outlet is plugged, flush one side.
Turn the water off, then remove the flushing
block. Turn it 90°, and reinstall. Flush the
other side.
