You make different sorts of leaky pipe. Different diameters and different flow rates at different pressures.
I recently bought some 20mm pipe from the UK for use in a gravity fed system which runs at 0.2 bar pressure. What I was supplied worked too well, 0.6 litres/minutes/metre. At that rate it owerwhelms the supply after about 6 or 8 meters of pipe.
What I'm looking for is leaky pipe that gives about 0.05 litres/minute/metre. And I'm sure that there are a lot of gravity feed irrigators out there that would use it.
Do you make it? If so where can I buy it?
Thanks
