Irrigation Hose

This is the hose we are using for the drip irrigation, with 16mm diameter, and 0,9mm width for the walls of the hose, this system must be anti-drain self-compensating drip, which we need in the floricultural area, this emisor must be 20cm distance from each other, for each 1.25 liters/h.
This system stars working only when the water pressure is the same in all the hose.
