I used this IBC tote lid for my dual IBC tank setup, and it works great. One tank is used for irrigation, while the other is a backup for dry periods. The lid’s vent holes allowed me to easily attach both an air escape fitting and an overflow fitting, which directs excess water into the backup tank when the main tank is full.This setup has been a game-changer, as I no longer need to switch hoses around when pumping water from my house rain barrel system into the IBC tanks. It’s been a convenient and reliable solution for managing my water storage.
