A tee valve includes a primary conduit configured to be connected to a water flow conduit. It includes an outflow tube that collects a portion of the water flow and directs it toward a fertilizer feeder along a secondary water flow path. An inflow tube connects to the primary conduit downstream from the outflow pipe to return the secondary water flow to the primary water flow path, with the secondary water flow return water now including a concentration of fertilizer or other water additive. In this fashion, any irrigation system can be used as a combination fertilizer delivery system.
