水泵扬程越高，同功率下流量越小，两者不可兼得；给花园浇灌需大流量选低扬程大流量泵，高楼层增压则牺牲流量选高扬程泵

Unverified潜水泵式浇水器需水桶/水箱蓄水，桶越大越少加水但越占地；重力式无需电泵更省电但需将水箱抬高安装，两者难两全83% similarUnverified内置排水泵（可向上抽水排放）与自然重力排水不同：普通连续排水要求排水口低于机器出水口，若需将水排到高处（如水槽、窗外）必须选带排水泵的机型81% similarUnverified过滤层数越多水阻越大，泵功率不足的低端饮水机搭配厚滤芯会导致出水量骤减甚至干烧，选滤芯需匹配水泵扬程81% similarUnverified通量越大越不用等水，但大通量机型往往取消储水罐直接现制，一旦膜衰减或水压不足出水会变慢，且大通量机功率高更耗电81% similarUnverified过滤层数越多、材质越复合，水流阻力越大，泵功率不足的老款饮水机会出现出水变慢或断流，选滤芯要看原机泵的额定流量匹配78% similar
