Abstract: PURPOSE:To measure exactly a standard water pressure and make it possible to effect exact hot water supply in a bath tub by projecting the end section of a hot water supply circuit into a bath tub and bending the section near the tip of the end section upwards into the bath tub. CONSTITUTION:The tip end section of a hot water filling circuit 17 is bent upwards in a bath tub 2 to form an upright section 49. Accordingly if a valve 4 inserted into the hot water filling circuit 17 is closed and water is filled up to the riser section 49 at the downstream end of the circuit 17, the air that is much lighter than water does not enter downwards into the upright section 49 filled with water so that the filled water does not leak into the bath tub 2. Consequently a reference water-pressure PO that is measured by a water pressure gauge 34 for the filled water which does not leak out is exact. After this the standard water pressure PO which is measured exactly is utilized to proceed the filling operation.
