The Flood and Drain fittings include a smaller (inlet) fitting and a larger (outlet) fitting. The inlets and outlets are used to pump nutrient into a tray to flood it, and to let it drain out, with approximately a 4cm flood of water as the outlet fitting (25mm) sits higher.
Once the nutrient level in the tray reaches the height of the outlet screen, the excess nutrient can drain back to a reservoir.
The extention can be adjusted for more height, and extra extentions can be added for a deeper tray.
The tub outlets supplied with these fittings have a 13mm barb (smaller one) and a 19mm barb on the larger one.
