Whenever you want to expand your Exo Terra Monsoon High Pressure Irrigation System, there is no getting around the original Y-junctions. Simply connect multiple terrariums to the system or add additional nozzles in existing terrariums. With the Monsoon Y-distributor, any expansion of the existing irrigation system can be easily implemented. And of course, the Y-distributor of the Monsoon irrigation system also serves as a spare part if the distributor should ever be defective.
