Checking function of SBS valve
To ensure correct operation of the SBS valve a caffe lungo should be made. During preparation
of the latter, check the difference in speed of delivery between the maximum and minimum
positions.
The difference in dispensing speed is approx. 2.5 times greater (and therefore VERY
obvious!!)
