So, all set up yesterday and works perfectly.750gph pump through 3/4" filter into 15m 3/4" pipe to 27m 1/2" pipe with 2lph non compensated drippers as no elevation change.Only thing i noticed on the wiring diagram is i had to jumper the +ve on the timer from input to switch as the juice does not flow through the timer and i joined negative from pump with timer negative for tidyness.I couldn't wait for the solenoid and yes it did syphon so i put a dripper in the pump line just above the water line in the butt to act as a syphon break and works perfectly!All hidden under an up turned bucket for waterproofing :-)Happy days.

Thanks Richard, i tested the pump running ¾" up the garden to ½" back down the garden and had good flow at the end.My only concern is that when all the drippers are in place the pump wont provide the pressure to drip as its centrifugal and will just sit there spinning?
hi Ross, thanks.I like the bilge pump idea for the butt due to the debris it will suck in. I was going to put a 3/4" filter after it before the rest of the system to stop the muck getting down the line.I've since found my water px gauge so will do a measurement and see what the pump can put out at the end of the run. Might determine what emitters I have to use.
Hi,Do you know how far the pump will pump?I was thinking of running a pipe around my garden and just using drippers/soakers at my fruit trees.It's about 30m length though.
