Ordering rainwater system

Before ordering rainwater system the following information is required:
• roof sketch with dimensions
• length of roof edges (L)
• height from the ground to the bottom of the eaves edge (Н)
• Width of the lower edge of the roof (C)

The diameter of the rainwater system and its assembly specification depends on the size of the roof and the hose, and its configuration.

One square meter of the roof area requires one square centimeter of cross-section of the downspout. Our rainwater system has 68 square cm cross-section. The maximum distance between downspouts should not be more than 10 meters, otherwise, as a result of heavy perception, downspouts will not be able to remove all the water from the roof. The shorter the distance between the downspouts, the less chance for water to freeze during cold winter periods as well as for falling leaves to stuck inside the downspout.

Required tools and additional materials

For high quality rainwater system installation, electric saw or circular sheet metal scissors, drill, riveter, silicone, nails and rivets are required.
Scratches on the surface of rainwater system components, caused during transportation or installation can be painted with the appropriate spray colour.

For cutting materials never use abrasive disks!

Rainwater system hanger installation

Hanger installation

Hanger installation

Gutter hanger installation begins at that eaves side that is designed to have a tilt towards the downspout pipe. The first and last hangers are mounted on the distance of about 150mm from the end of the eave.

The first hanger is mounted so that the distance between an imaginary extension of the roof surface and the gutter should be at least 25mm. It is recommended not to fasten one of the screws till the end in order to bind an equalizing cable to its threshold.

The next hanger on the end of the eave plank is attached in accordance with required inclination of the gutter. The recommended inclination of the gutter is around 2-3mm per meter of the drain. This hanger is also left unfastened with one of the bolts/screws and an equalising cable is fastened to it.

Gutter hanger assembly distance

The distance between gutter hangers should be no more than 900mm. The remaining hangers in accordance with the equalizing cable are attached to the eaves edge. At the end it is required to fasten the unfastened bolts/screws to which the equalising cable was attached.

Drop outlet assembly

Gutters should be placed into the hangers with the maximum precision. It is not recommended to move the gutters back and forth after the installation is performed as it may scratch the point.

Gutter joining

Before connecting the gutters the water flow direction should be taken into account. Gutters are connected by placing them into each other. The connection overlap length be at least 10cm. The place of junction must be filled with silicone and fastened with rivets.

Downspout connection.

It is easy to connect downspouts and elbows together as one of the ends is more narrow than the other. The length of downspouts can be reduced by cutting not narrowed side away with the help of the electric saw.

Downspouts should be located 30 – 40 mm from the wall. It should be taken into account when downspout with inclination is installed.

The bottom downspout elbow should be located at least 300mm above the ground. This should be taken into account when cutting vertical downspout according to the required size.

Downspout strap mount towards the wall should be accomplished at the same level as the joint place between two downspouts or the downspout and elbow is. Each downspout requires at least two straps. The distance between straps must not exceed 1,5 meters.

Downspout and elbow are usually connected together on the ground, then it is connected to the gutter’s drop outlet and then with the help of a strap mounted to the wall.

Maintenance

In order to ensure longer exploitation period of a rainwater system it has to be regular checked and maintained.

The rainwater system should be checked at least once a year (preferably in spring) as the rain is not always completely washing out accumulated tree leaves, needles and other garbage that is stuck inside gutters or downspouts.

Rainwater system should be cleaned accurately otherwise scratches may show up on its surface.

It is allowed to clean rainwater system with water and soft brush. The water jet pressure should not exceed 50 bars. Painted surface cleaning agents are also allowed to be used. After agent is applied it should be left for several minutes to start working and then gently washed away with the help of large amount of water.
