Water Delivery Example -
The flow rate is controlled and regulated by the shut off tap provided. Initially we suggest you should set the drippers to deliver around 1 drip every 10 seconds, and monitor the amount of water delivered over a short period. If more is necessary open the tap slightly. If less is needed then the tap can be closed, the tap only requires extremely fine adjustment!

Multiple tanks can be linked into a system to give increased capacity.

The tank should be raised so that the outlet is at the very least the same height as the drippers, for the best results the tank should be raised as high as is practical.
