放水 (fàng shuǐ): to turn on the water; to let water out; (sports) to throw a game

Mom asked me to run a bath for the child. I first cleaned the bathtub, then turned on the faucet to fill it with water.

The pond in the garden hadn't had a water change for several days, so this afternoon Dad decided to drain it and then fill it with clean water.

When camping, we filled buckets with water from the lake to wash vegetables and put out fires, but we had to boil it before drinking.
