2 bar equals roughly 30 PSI, which is pretty low for a sprinkler system, coupled with the 12 LPM that equals slightly more than 3 GPM, which is also pretty low for any sprinkler system.

That might well seem to be your main problem.


It's a matter of pressure and flow and I believe you're exceeding the limit of the pump and well delivery.

I think what you might need to do is break the drip line into 2 or more zones for it to be effective in watering.


I have 60 PSI and 7 GPM at the beach, and even then to get good coverage, I needed 4 zones running impulse heads, misting heads, and a drip line.
