ABSTRACT:
An air bleeder valve for a waterbed mattress comprises a hollow tubular body sized to fit snugly into the fill spout of a waterbed mattress, a flap valve at one end of the body, and a porous, non-water absorbing water barrier in the tubular body for preventing water from splashing out of the mattress when bleeding air from the mattress.
