Sewer valve

Sewer valves are water-controlling devices found just south of Ardougne. They are used in Hazeel Cult quest.

There are 5 sewer valves total. Each has a "turn-right" and "turn-left" options.

Just east of Clocktower is a dungeon entrance. There is a raft. When boarded, this raft will take you to different places due to the position of all 5 sewer valves.
