An additive dispensing apparatus for a fluid system is disclosed which includes a head having a body portion adapted and configured for fluid communication with the fluid system and having a flow path extending therethrough. A fluid inlet portion of the flow path defines a relatively high pressure region and a fluid outlet portion of the flow path defines a relatively low pressure region. A canister is operatively associated with the body portion and structure is provided for facilitating fluid communication between the fluid inlet portion and the interior of the canister. A collapsible container is disposed within the canister for containing a liquid additive for dispensement into the fluid system and structure is provided for facilitating fluid communication between the collapsible container and the fluid outlet portion, whereby the differential pressure between the interior of the canister and the interior of the collapsible container effectuates a proportional dispensement of liquid additive into the fluid system.
