A housing has an upper end, a lower end, and an opening extending between the upper and lower ends, the housing being sealingly attachable to an inflatable device. A check valve has a body member with an upper end, a lower end, an outer surface sized and shaped to be selectively matingly received in the opening of the housing, and an inner surface defining a passageway. The check valve is coupled to the housing by a first tether. A cap has an upper end, a lower end, and an outer surface sized and shaped to be selectively matingly received in the passageway of the check valve. The cap is coupled to the housing by a second tether. |
