如果你使用一个没有用过或大约6小时没用的水龙头，首先要开着水龙头让水流出来，冲洗水管，直到水变得跟正常一样冷。

If you're using a faucet that hasn't been in use for the past 6 hour or some, first flush the piped by letting the cold water run until it's as cold as it will get.

第一步就是用小石子排满排水区域，这样管理员就可以避免在用水管冲洗地面的时候把沙石冲到排水沟里面。

The first step was to line the drain area with small stones. This enables the keeper to hose the small stones covering the concrete without the stones washing into the drain.
