Plumbing For Large Interior Living Walls
For a living wall measuring over 18 square feet the plumbing and all other necessary equipment is located either outside or on the opposite side of the wall on which the garden will be installed.
Plumbing (one drain line and one cold water line) is installed through the wall to connect the equipment to the garden.
A timer and irrigation valve draw water out on a set schedule, send it to the fertilizer injector to be fertilized and then through cold water line and up to the top row of plants in your garden.
A collection basin or gutter is installed underneath the planters. The collection basin collects the water that drains from the bottom of the planters and directs it through the drain line out to either the equipment or the installed drain.
