Running several drip lines together, at about 6 to 8 litres per minute. Is this enough flow rate for it to work properly?

Drip systems with less than 8 litre per minute water flow may require an EZ-FLO Flo-Disc in order to inject solution into the drip system. There are three “Flo” discs provided for these conditions.

EZ-FLO can operate at about 2 litres per minute as a minimum.
