Abstract

An air massage system for a bathtub comprises a blower, an air distributor and the water jets. The air distributor connects the blower to the jets, and the jets are adapted to deliver air under pressure to the cavity defined by the bathtub. The jets include water check valves to prevent the water in the bathtub from entering the air distributor. The air distributor comprises at least one water relief valve for preventing water from reaching the blower, when inoperative, in the event of failure of any one of the water check valves. The air distributor also comprises a main pipe, a manifold and distribution pipes, with the main pipe connecting the blower to the manifold and the distribution pipes connecting the manifold to the jets. The water relief valve is provided on the manifold, and the water check valves are provided on the manifold and at each jet. A pressure relief valve is provided upstream of the jets for keeping a substantially steady pressure from the air propelled by the blower.
