Æ 7.02 – Water Debit

Espresso machine technicians often measure water debit in units of millilitres per 30 seconds (ml/30 sec). To measure your own machine’s water debit, simply place a pitcher under the group head, turn on the pump, and start a stopwatch. After exactly 30 seconds, stop the pump and weigh the amount of water that has flowed into the pitcher. Ideally, take several readings and calculate an average.
