Its up and running and working well, and when the main 3000 litre rainwater reservoir is over one third full it is gravity fed, so the pump is just for back up. The top blue drum, is connected to the main reservoir, and controlled with a float ball valve, as is the middle tank, the first being a fine mesh filter , and the middle being a fine sand filter.
So I am well pleased, as I think that will be my last big project, having put eight raised beds, and the system since November of last year.
