PROBLEM TO BE SOLVED: To provide water supply equipment, and a valve element and a filter using the same, capable of automatically preventing reduction of an amount of through water when a filter is clogged.SOLUTION: Water supply equipment 100 includes a water-tight casing 10 having a water inlet 11 and a water outlet 12, a chlorine removal filter 30 disposed in the casing 10, filtering the water flowing into the casing 10 from the water inlet 11 and allowing the water to flow out from the water outlet 12, and a bypass passage (hollow portion 31) capable of communicating with the water inlet 11 and the water outlet 12 in a direct connection state. A valve element 50 is disposed for opening and closing the hollow portion 31 by opening/closing motion when a water pressure in the casing 10 rises and falls with respect to a predetermined working pressure. In a flow channel 52 of a main body portion 51 of the valve element 50, a pressure opening/closing valve 53 is disposed.SELECTED DRAWING: Figure 3 |
