Rainwater Guttering Beginners Guide
November 6, 2009
To direct water away from a buildings base a Rainwater system is normally used. They also help to reduce erosion, prevent leaks in basements and crawlspaces, protect painted surfaces by reducing exposure to water, and provide a means to collect rainwater for later use.
Popular materials for guttering systems include metal, GRP, copper, zinc, plastic and timber.
Rainwater gutters collect water from the roof and drain it down a leader pipe to the bottom of the building where it is collected or directed to a drainage system. Collected water from a gutter can be stored in a cistern or barrel.
A combination of the following components make up a Rainwater System.
Gutter – the gutter pipe stretches around the perimeter of the building just below the roof tiles to gather water as it drips off. A wide range of profiles are available for gutters to match the aesthetics of the building.
Down Pipes direct the water from the gutter to the drain or collection barrel. The pipes will be made up of a series of pipes and joints so it can be fixed to the building.
Hoppers – used to channel other pipes into the down pipe.
Accessories – brackets, clips, ends and outlets are used to connect the rainwater system together and to secure it to the building.
To filter out roof debris such as leaves, moss and broken tiles many rainwater systems will include a louver or screen above the main gutter pipe.
Most modern guttering requires no maintenance other than periodical cleaning out. If blocked then water can overflow down the side of the building. Stagnant water in gutters can encourage weeds and grasses to grow.
