Installation of drainage system starts with marking
Chutes and pipes can be made of metal or plastic, the final choice depends on various factors, including on what costs you are willing to go. It is logical that the lifetime of the metal elements of the waste system is much greater than that of plastic, but the latter are much easier and easier to assemble. However, some moments of how to install a drainage system, do not depend on the material.
In the beginning, a markup is made for placement under the overhangs or at the ends of the rafter legs of the brackets under the chutes, and it does not matter what they will be from. It is only necessary to take into account the shape of the tray, which can be semicircular, trapezoidal or rectangular. The easiest way is to install the drainage bracket on the front plate, in this case you simply make the next mark 2-3 meters above the through each meter.
You can mount the fasteners and the rafter feet, if the roof construction allows it. Unlike the brackets on the windboard, which are most often plastic, installing a drainage system at the ends of the rafters involves the use of brackets made of metal. They have one distinctive feature - you can adjust the height of the bracket, bending the base, which is screwed to the beam of the rafter.
Gutters installation, sequence of actions
When all the holders are installed, you can start assembling the gutters. The technical features of the process directly depend on the material from which the trays are made. The fixing of gutters made of plastic does not cause any difficulties, for the connection of individual elements, glue or rivets are usually used, for metal gutters a reclining recess is better suited. However, not all can be joined with folds, so the riveting machine will be needed when assembling the tin trays.
Polymer elements are connected very simply, with the help of locking locks, which are available at the ends of each tray. This is the way, for example, a cap is put on, completing the trough with a kind of transverse wall. At the corners around the corner of the building are installed special corner elements( such are in metal and plastic kits).To get a qualitative installation of gutters with your own hands, video instructions will not hurt you.
It is noteworthy that the funnels made of metal are fastened on special fasteners, just as it is provided in many plastic systems. However, the fixing of the drainage system from polymers is often carried out on glue. In some metal kits, the funnel mouth is not present as such, instead of it, from the inside of the tray, a flange connection is inserted into the hole in the base .The area under the flange is smeared with silicone sealant, then the connection to the tray with rivets follows.
Fixing the drainage system - general moments
If the brackets are installed, and the future slope of the trough is met, the installation can begin. The fixing of the drainage system starts from the same gutter, to which the funnel of the drain pipe will be connected. A hole is cut in the tray, the diameter of which is sufficient to prevent the sediment from accumulating in the gutter, but not exceeding the diameter of the funnel. The remaining troughs are laid from the one in which the hole is made, overlapped.
Very often, in order to economize when installing gutters, the brackets are installed at large intervals, in terms of safety factor, but this leads to trough deflection and deformation of the entire system.
Before fixing the gutters, it is necessary to make sure that in the place chosen by you, nothing will interfere with the installation of clamps and the installation of pipes. In particular, on the wall may be cornices and other projections, they are recommended to continue the excavation. If there is nothing left but to install gutters to bypass obstacles, knees are used, although the drain should be as straight as possible. A tip with a lateral hole or an adapter to the manifold pipe is made below. You can also use a nozzle with a trough to fill the barrel with rainwater.
