PURPOSE:To prevent the deterioration of a rubber hose by a method in which a chlorine remover is set on the upstream side of the rubber hose to remove chlorine present in supplied water and hot water flowing in the rubber hose. CONSTITUTION:A chlorine remover 12 is set on a chlorine removal section 2 of upstream side of a rubber hose used in the path through which water and hot water are supplied. The chlorine remover used is adsorbent such as activated carbon or compounds containing one or more oxides selected from the groups of magnesium, aluminium, and silica in the form of granular, block, or powdery solids having great surface areas. Since the inner surface of the rubber hose is protected from effects of chlorine in water, the deterioration of the rubber hose can be prevented. |
