LEAD: A WELL- The gutter system that plays a role is essential. Without rain and dripping snow from the roof, it is easy to saturate the ground around the foundation, causing leakage and settlement of the basement. If the Tiangou system is seriously damaged and the maintenance is neither practical nor economical, a new system should be installed immediately to replace it.

If the Tiangou system is seriously damaged and the maintenance is neither practical nor economical, a new system should be installed immediately to replace it. Aluminum and vinyl are the most popular materials for the new sink, as they do not need maintenance other than cleaning. In this country, aluminum sinks are used more time than vinyl ( It has been popular in Europe for many years) , But in terms of cost, durability, or assembly difficulty, neither has a big advantage over the other two. The painted aluminum sink may become sunken. If scratches appear, it will be obvious at close range. However, if it is hit by heavy branches in cold and warm weather, the vinyl sink will break, the vinyl material will expand and special installation technology is required, while the aluminum remains stable. The aluminum gutter part is connected by sealing with the mastic. The vinyl gutter section is sometimes built- In a neoprene or plastic gasket, but usually need to be sealed with a special silicone rubber sealant or solvent Similar to the Foundation cement used to connect plastic pipes. The first step in installing the new gutter system is planning. Draw a bird\'s- The view of the roof outline. The dimensions of each side of the roof or section are shown above ( Hanging like a porch) Which templates must be connected. In general, this simply means copying the existing drainage system. However, if the remodeling changes the shape or size of the original roof, or if there is a problem with the drainage system of the drainage ditch due to insufficient or improper installation of the downpipe, some redesign may be required. Whether the diagram represents a straight line length or several segments connected at an angle, a drain of no more than 40 feet should point to a downpipe. In places where heavy rainfall is frequent, rainfall should be reduced to 30 feet. The downpipe must also be placed at the low point of the drain system so that the sink can be tilted to cause the water in it to flow. Usually, the Downpipe is located around the corner, the sides of the building meet, or the two length drains are connected at a certain angle, however, the long length drains can be tilted to the center, it is also possible to tilt towards the downpipe located at each end. After planning the gutter system, bring the drawings to the dealer or get a chart from the dealer showing the various gutter components available. Use the chart to determine all the components you need. There are many styles of brackets hanging the gutter part. The gutter section is usually 10- Use a hand or chainsaw saw to trim shorter foot lengths. For vinyl gutter, be sure to purchase sealing or adhesive materials for the brand that joins the gutter section you will be using. Roof area up to 750 square feet, 4-inch- The wide sink is usually enough. The area is between 750 and 1,400 square feet, please choose 5-inch- Wide sink, 6-for larger areas-inch-wide gutters. Downpipe with 3- For roofs up to 1,000 square feet, inch diameter is usually enough. For larger roofs, use 4-inch-Hole diameter. Assembling and fastening the guttter system first requires careful marking of its position on the building, usually on a wide plate called the fascia, which is the upper edge of each wall that meets the roof. The position of the gutter shall cause the center of its trough to be directly under the edge of the roof material. It must also be tilted at the right speed, usually between 10 feet inch in 1 quarter and 1 inch 16 feet. The highest point of the length of the gutter should be placed on the upper outer edge of the gutter- Below the slope of the steep roof or up to 3 inch Quarter- For a relatively shallow roof, it is an area of one inch. Typically, this position corresponds to the height of the line extending from the top surface of the roof sheath, as shown in the figure. After dismantling the old ditch ( If the gutter is made of wood, molded below) , Driving a nail or installing a drain bracket at the point you identified will be a high point running along the wall, which should also be the longest running of the system. Install a second nail or lower spray connection at the low point on the wall. Then stretch the chalk line between the two nails or brackets, spray it down and snap it onto the fascia. Repeat the process along other walls. When installing the drain, align the upper edge of it or the upper edge of the bracket with the line. Assemble as many parts of each drain on the ground as possible. Then, with the help of one assistant per 20 people The foot length of the ditch, raise each part and fix it to a high point and then to the water outlet. Then install the bracket in 24-to 30- Inches apart. Finally attach the downpipes, slide them into place from below, and then fix them on the wall with straps. Use two straps for every 10 feet spout. On the ground, place the splash block below the elbow of the spout.
