We have system setup with c. 75m of drip pipe (spec : [Link: rainbird.com]).

At the programmer end we get c. 2 bar pressure, 12L per minute flow.

I stuck the pressure meter on the end of the 75m run and ran the system for a few minutes and seems we are getting 1 bar of pressure at the end of the run.

The problem is that the ground doesn't seem to be getting wet, even after a pro longed 3 hour run. The ground is wet directly under the drip locations with a small c. 10cm puddle, but not along the whole length of the pipe.

Dose this sound right and if not what can be done to improve the system ?
