A personal water and additive apparatus includes a first container; a manifold having a water passageway and an additive passageway, the water passageway and additive passageway intersecting to form a single mixing passageway; a first tube connecting the first container to the water passageway of the manifold, the combination of the first tube and the water passageway defining a water channel; a second container; a second tube connecting the second container to the additive passageway of the manifold, the combination of the second tube and the additive passageway defining an additive channel; an outlet tube having one end connected to the mixing passageway of the manifold; a check valve disposed in the water channel; and a flow regulator that controls flow in at least one of the water passageway and the additive passageway.
