The pump draws up to 21 litres every minute and many domestic taps cannot supply that consistently. A quick check: time how long your tap takes to fill a 10 litre bucket. If it takes longer than about 29 seconds, the tap is delivering less than 21 LPM and you should feed the machine from a buffer tank or water-storage tank.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat size buffer tank do I need?\u003c\/summary\u003e\n\u003cdiv class=\"a\"\u003e\n\u003cp\u003eIt depends on how much water your supply delivers. The tank only has to cover the shortfall between your supply and the 21 LPM the pump draws. For example, if your tap delivers 12 LPM, the shortfall is 9 LPM, so a 250 litre tank gives you roughly 28 minutes of continuous spraying before it runs dry, and it refills whenever you release the trigger.
