What can I do to stop the siphoning without raising the babies or just watering by hand.
this is how it is,
water butt(stands approx 1.5m tall) pump in the bottom 13mm pipe up over the side of the butt and down and reduces down to 4mm pipe at the pots (all pots have adjustable drippers)
when the timer turns the pump off the water butt is drained completely because the water is siphoning caused by the the pump
