Using a high flow booster pump “we now are selling Aquatec pumps” I demonstrate how to drain a high pressure aeroponic system. First I close the tank valve, second the reservoir valve and third open the return valve from the system. Once I open the drain line the pump turns on and begins removing the left over nutrients within my system. Once drained, close drain line and open the valves again making sure to close the return valve. I have a one way check valve on the return so if I don’t close the valve nutrients don’t empty from the reservoir into the system.
