Collecting rainwater from the roof

To save the walls from rain water and discharge it from the roof gutter semicircular or rectangular (rarely V-shaped) profile. Gutters are made mostly of galvanized steel. At the side of tin gutters for increased rigidity roll steel wire with a diameter of 3 mm. In recent years, as the gutters are using PVC pipe halves. Depending on the location of gutters are hanging and wall. All gutters should have a slope of 0,005-0,015 (5-15 mm at 1 PM). Profile trough area due to the roof, from which it drains the water. Approximately 1 m2 of the roof should account for 1 cm2 of the gutter. For example, a square chute for the roof area of ??50 m2 must have dimensions of about 7x7 cm Gutters are made to be functioning as a length of 200 cm depending on the profile: 120,160,200 semicircular diameter and 240 mm for water drainage from the roof area of ??50,90,150 and 220 m2 square gutters are made from elements of the size 50x50; 88x80; 100x100 and 130x130 mm. Clamps made of sheet steel for attaching gutters need to be strengthened durable, because in a strong flow on each meter trough around 20 kg of water. At the top end chute tip at the bottom - a funnel through which water is drained into the sewer. Downpipes are made of prefabricated length of 200 cm diameter pipes should be such that 1 m2 of the roof had 0.8 cm2 area of ??the pipe. Elements inserted one into the other (top to bottom) at 6 cm are fixed elements to the wall in increments of 2 m. The bottom of the downspout goes into a concrete gutter, with a gradient. Hanging gutters can be hung on hooks on the clamps. Clamps can not do long, since the heavy rains the water gush through the chute. Instead of drain pipes by the end of the gutter can be tied a thick rope with a weight at the end of a round wooden stick. Water flows in these guides and do not sweat or rainwater from the barrel. In winter it is desirable to remove the gutter, as they are destroyed by ice. In recent years, domestic manufacturers have mastered the production of drainage systems with square section of metal-coated variety of colors, as galvanized steel and copper, which are a good complement of metal roofing. Standard length manufactured gutters - 3000 (other sizes made to order). To assemble the metalocherepitsy or roofing gutter holders fixed to a distance of approximately 90 cm from each other in the biggest load: closer to the ends, turning corners, joints gutters downpipes. In places the load on the gutter is recommended mount additional suspensions for greater reliability. In the joints of gutters are inserted into each other, the joints are sealed with sealant and fastened with rivets. Previously in the gutter is cross-shaped hole for the funnel, the edges of which are bent outward. The exhaust cone attached to the gutter rivets, the joints are sealed with silicone. The ends of troughs are closed plugs that are pressed, are placed on the sealant and fixing rivets. By the final crater riveted joins knee or downspout with a knee. Pipe cut to desired length and attach to the wall holders at a distance of 150-190 cm from each other. Downpipes are manufactured length of 2000 and 3000. Downspout to the elbow have a length of 1000 - and 3000 + knee knees. The recommended distance from the bottom of a drainpipe to the ground not more than 30 cm
