The purpose of a leader head is to help transfer excess water from the roof onto downspouts, thus preventing the gutters from overflowing and water washing over the walls, which is a common occurrence in areas susceptible to heavy rain cycles. The use of leader heads also offers other benefits to the drainage system.
Rain gutters can be equipped with gutter screens, micro mesh screens, louvers or solid hoods to allow water from the roof to flow through, while reducing passage of roof debris into the gutter. [21] Clogged gutters can also cause water ingress into the building as the water backs up.
Downspouts are usually vertical and usually extend down to ground level, although may be routed at an angle to avoid architectural features and may discharge onto an intermediate roof. At the bottom of downspout there are typically features to divert discharged water away from the building's foundations to prevent water damage.
In the U.S., every plumbing fixture must also be coupled to the system's vent piping. [1] Without a vent, negative pressure can slow the flow of water leaving the system, resulting in clogs, or cause siphonage to empty a trap. The high point of the vent system (the top of its "soil stack") must be open to the exterior at atmospheric pressure.
[3] [4] Most municipal storm sewer systems discharge untreated stormwater to streams, rivers, and bays. This excess water can also make its way into people's properties through basement backups and seepage through building wall and floors. Urban runoff can be a major source of urban flooding and water pollution in urban communities worldwide.

A drain is the primary vessel or conduit for unwanted water or waste liquids to flow away, either to a more useful area, funnelled into a receptacle, or run into sewers or stormwater mains as waste discharge to be released or processed.
