[0018]
In this way, if the supply tap 13 is provided on the ball tap 9 in a branched shape so that the amount of supply water flowing into the supply tap 13 can be adjusted at the entrance side or the exit side, the ball tap 9 can be used to form a siphon-type toilet. Can also be used in wash-out toilets, etc., and when installed in wash-out toilets, etc., the adjustment ring 16 can be tightened so that makeup water does not flow into the makeup water pipe 13 side. Therefore, it is sufficient to prepare one kind of ball tap 9, which can reduce the product number and reduce the cost.
[0019]
Even in flush toilets, etc., on-site, the toilet may be water-sealed due to siphon phenomenon in the piping. However, since supply water could not be supplied in the past, measures against water-sealing were taken. Although it was impossible, by using the ball tap as in this example, even when such water seal breakage occurs on the site, the adjustment ring 16 is turned to supply makeup water to the makeup water pipe 13, It becomes possible to cope with water blockage on site.
Further, by adjusting the adjustment ring 16 as appropriate, only a necessary amount of makeup water can be supplied to the makeup water pipe 13, so that no excess makeup water is allowed to flow and a water saving effect can be obtained.
