Unpowered Wicking Valve
Published on by Bernie Omodei, Owner at Measured Irrigation for Measured Irrigation
Let me show you why the Unpowered Wicking Valve is preferable to any Smart Wi-Fi Irrigation Controller.
No solenoid valve required
No wiring required
No power required
Dripper discharge is independent of dripper flow rate
Assuming that all the drippers are identical, the amount of water discharged by each dripper during the irrigation event is the same for 4 L/H drippers as 2 L/H drippers
The gap between the upper and lower float determines the dripper discharge.
Set to any volume between 200 millilitres and 2 litres.
NPC dripper discharge is independent of the water supply pressure
Responds to onsite evaporation and rainfall
The irrigation frequency increases significantly during a heat wave
When it rains, water enters the container and delays the start of the next irrigation
Only one zone required for PC drippers
With a smart wi-fi irrigation controller, multiple zones are usually required for PC drippers so the pressure is within the pressure compensating range. However, with the Unpowered Wicking Valve, there is no restriction on the pressure range and so a single zone can be used
