水是宝贵而有限的资源,珍惜水源、节约用水已是当务之急。过去,卫生间大便器冲洗设备,普遍使用高、低水箱,这种设备不仅耗水量大(冲洗一次耗水12～18升左右),且水箱零件常常失灵,因而普遍存在大便器漏水现象。一个大便器漏失的水量,每昼夜可高达八吨多,而一般企、事业单位都有几十、几百个,乃至几千个大便器,如若维修不及吋,其漏失水 Water is a precious and limited resource. It is imperative to cherish water and save water. In the past, bathroom toilet flushing equipment generally used high and low water tanks. Such equipment not only consumed large amounts of water (approximately 12 to 18 liters of water for flushing once), but also the parts of the water tank often malfunctioned, so that there was a widespread phenomenon of leakage of the toilet. The amount of water lost from a toilet can be as high as eight tons per day and night. In general enterprises and public institutions, there are dozens, hundreds, and even thousands of toilets. If it fails to repair, it will lose water.
