However, in the above-mentioned tap water pipe facility, tap water in the pipe will stop unless the valve provided for each facility is used. Especially, the water accumulated inside the equipment that is not used for a long time,
Water in the pipe between the piping pipe and the valve may remain stopped, resulting in deterioration of water quality or rust inside the pipe. Furthermore, since metal salts are dissolved in tap water and oxygen, carbon dioxide, etc. are dissolved, the scale is accumulated inside the pipe by the metal salts, or the oxygen, carbon dioxide, etc. dissolved in water are dissolved. Based on the above, there was a risk that acid corrosion would damage facilities and the like. There is also a problem that scales may adhere to the inside of the pipe or brown water may come out due to corrosion and may be harmful to human health.

Next, the operation of the present invention will be described. First, when the valve (6) of the bathroom unit (B) is opened to describe the flow of tap water when water is spread over the bathtub, tap water is introduced from the main pipe (1) into the water supply pipe (3), and -Turn (2) operates. Further, the tap water that has passed through the check valve (9) is introduced into the pipe (4) for piping, and tap water is poured from the valve (6) into the bathtub. At this time, the flow of tap water is detected by the limiter (10), so that the pump (14) which has been driven until now is stopped.

When the valve (6) is closed after tap water is filled in the bathtub, the flow of tap water introduced into the piping pipe (4) is stopped and the state is maintained.
In the present invention, at this time, the pump (14) starts to be driven by detecting that the tap water is not flowing by the limiter (10). As a result,
The tap water inside the pipe, which has a circulation channel formed as indicated by the arrow, is circulated by the pump (14) among the water supply pipe (3), the piping pipe (4), and the condensate pipe (13). , Tap water can always be circulated. Therefore, there is no longer the conventional state in which the water accumulated in the equipment that has not been used for a long period of time or the water in the pipe between the piping pipe and the valve is always stopped and does not flow. As a result, the water quality does not deteriorate, and the risk of rust inside the pipe is eliminated. still,
The circulating water channel referred to in the present invention is a state in which tap water can be circulated among the water supply pipe (3), the piping pipe (4) and the condensate pipe (13), and the tap water main pipe. When the flow of tap water from (1) is stopped, the pump (14) is driven and the tap water constantly flows and circulates.

Next, the function of activating tap water that has passed through the invention will be described. First, tap water is introduced from the main pipe (1) into the water supply pipe (3), passes through the check valve (9), and reaches the purification device (11). Even when tap water does not flow from the main pipe (1), tap water is supplied to the pipe (3),
It circulates between the piping pipe (4) and the condensate pipe (13). In this case, the tap water returned to the water supply pipe (3) always passes through the purifying device (11). The purification device (11)
By passing through, the metal salts dissolved in tap water, dissolved oxygen or carbon dioxide, etc. are filtered in the primary active water tank (11a) or neutralized in the secondary active water tank (11b), and the Water becomes alkaline. As a result, there is almost no risk of damaging equipment or the like due to acid corrosion that has conventionally occurred, and it becomes difficult for the scale to adhere to the inside of the pipe, and alkalized drinking water is considered to be good for human health. It will be. In addition, since a certain amount of tap water is stored in the purification device (11), it serves not only as a water storage tank in the event of a disaster, but also as tap water changes to alkaline, it also serves as an antioxidant. Will be things.

When the purifying device (11) is replaced or disassembled, the pump (14) is first stopped and the maintenance valve (12) is closed. Then, the necessary construction is performed. At this time, the construction can be performed while supplying tap water to each facility without stopping the water supply from the main pipe (1). That is, tap water reaches the piping pipe (4) from the water supply pipe (3) through the maintenance bypass (15), and a plurality of valves (5), (6), which are attached to each facility,
(7) and (8) may be used in the normal state.
