ABSTRACT:
A bath, into which water is to be pumped for hydrotherapy, is disclosed and in which the drain and overflow pipes from the bath and the return line to the pump are connected to a junction leading to a waste pipe. A valve in the junction directs water from the drain pipe to the return pipe but not to the waste pipe while allowing overflow water to flow into the waste pipe. After the bath has been used, the valve may be opened to drain the bath, drain and return pipes to waste.
