A 1992 federal law mandated showerheads couldn't use more than 2.5 gallons of water per minute.
1992年出台的一项联邦法律要求,淋浴喷头每分钟的出水量不得超过2.5加仑。
But, as new showerheads came out over the years with multiple nozzles, the Obama administration said the showerhead restrictions apply to what comes out in total, meaning multiple nozzles have to split the 2.5 gallons of water.
但几年以后市场上出现了新型多喷头淋浴设备,于是奥巴马政府提出,2.5加仑出水量为所有喷头出水量的总和,这意味着多个喷头也必须符合这2.5加仑这一总量限制。
