PVC is most common form of downpipes installed by the home handyman or 'DIYer'. Below are installation instructions for Skyrise brand downpipes.

You will require a hammer, hacksaw, cloth, ladder or trestles and planks, measuring tape, pencil and rule.
Skyrise Construction can cope with a peak rainfall of 200 mm per hour providing they are correctly installed.

When more than two angles occur in a system the recommended roof area served by a downpipe should be reduced by 5 square metres for each additional spouting angle.

Downpipe installation.
Assemble downpipe, using angles if there are soffits. Where a downpipe has a socket on it the socket on the long section of the bend can be sawn off. This will enable the remaining spigot to fit into the downpipe socket.

By cutting the socket off the long end of a downpipe bend, a tight offset can be made.

Pipe and fittings should be solvent welded together with Marley MCS Welding Solvent Cement; but do not solvent weld the downpipe socket or top bend to the rainwater head outlet.

The downpipe should be fixed to the wall using three pipe clips per length. By using non-corrosive screws to fix the downpipe clips, the downpipe can be removed in the future.

Painting
After installation, Marley downpipes can be painted to any desired colour.
To prepare the surface, wipe down with a bath cleaner, and thoroughly wash. Once dry, apply two coats of acrylic paint ensuring the first coat is dry prior to applying the second coat.

Maintenance
To ensure your new Marley downpipes maintain their good looks for years and years, an annual cleaning using warm soapy water and a car cleaning cloth is all that is required. Simply rinse off with clean water.
