Determine the angle of the sewer pipe : assembly of pipes

Hello dear subscribers construction portal Stroy-Shkola.ru.In this article, we discuss with you the process of laying sewer pipe, namely Let us give attention to the slope of the sewer pipe.So we go.

slope sewer

One of the main factors responsible for the comfort in your home, apartment, is the proper operation sewerage system.Particularly acute, this problem in older homes with iron drain required.Over time, these cracks and leaks.Currently, the most popular material for producing sewage pipes are polymers.Plastic pipe is very easy to install and available for installation even professionals.

Required tools and materials

For independent installation of sewerage plastic tubes you need the following tools and materials:

• -private pipe (diameter of 5 cm to drain waste water and 10 cm risers),
• -soedinitelnye elements(taps and fittings),
• -condensing cuffs,
• -special adhesive for plastic pipes,
• -karandash, roulette, building level, a saw.
• -with necessary - cement.

ready to work

examine the old sewer system and fix all parameters.You can take pictures of the construction of the old system, so it will be easier to install a new one.

1. Take a piece of graph paper and make it to the wiring diagram of sewer pipes.Do not forget to place elements of plumbing and the distance between them, including the central tube of the riser.
2. Check the drawing to the actual distances between nodes of sewage in your apartment.
3. encourage you to repeat the old wiring diagram of sewer pipes.It is usually done by professionals and there is no need to change it.
4. basis of the sketch and the actual distances, calculate the required amount of plastic sewer pipes and connecting elements.

calculation of minimum slope sewer

Calculate the minimum angle of the sewer pipe may be on a special, rather complicated formula.

formula for calculating the minimum slope sewer

However, we can not take into account the algebra and use the ready-made solutions.

Standards slope of pipes of different diameters on a length of 1000 mm

Slope horizontal sections of the sewer system pipes should be not less than "0.02".That is, in the area of ​​sewage water pipeline length of one meter height difference at the ends of the pipe should be two centimeters.

However, a small volume of waste transported, this is indicative can be increased up to "0.03".Thus, if you navigate from one portion of sewage basin, the level must be lowered on tubing three centimeters per meter pipe.

Tips for choosing pipes

1. sewage plastic pipes are gray in color.Pipes of different diameters designed to perform certain sewage nodes.
2. not need to deal with calculations - simply measure the diameter of the old pipe, pick up the plastic pipe the same diameter.
3. However, you can take advantage of, and a reminder: so when installing the drain in washing machines and posudomochechnyh use pipes with a diameter of 2.5 centimeters, the installation of flow showers and bathroom - with a diameter of 3.2 centimeters, pipe conveying sewage in the apartment havea diameter of 5 cm, and used for the main risers 11 centimeters.
4. Similarly, the length of the old pipe and selected footage plastic sewer, after the establishment of the scheme sewer layout, you can count the number and configuration of the connecting elements.

Disassemble the old pipe

After the inspection and measurement of the old sewer systems, drawing up schemes wiring pipe with all the connecting elements can begin to dismantle it.

1. examine the old cast iron pipes, define the elements that during removal will require additional work (eg, pipes passing through walls.
2. Cooking tools required.
3. Turning off the water supply to the premises and warn the neighbors above about the beginning of the demolition work.
4. carefully working chisel begin the dismantling of the iron pipes should be to ensure that the fragile pieces of iron at during dismantling do not end up in the trunk sewer - this can result in damage to its failure
5. to dismantle the pipe section adjacent to the trunk.riser, you can simply cut off her grinder. this procedure means that if you do not replace the main riser.
6. If the connection of cast iron pipes are fixed with the help of sulfur (this can be verified by the characteristic odor after heating connections) the dismantling of the connections of the pipes should be carried outusing a gas burner.Please note that this work is best done in a respirator.

further work on the installation should begin after full cooling of the connecting nodes.

main methods of installation of plastic sewer pipes

There are two basic ways to install plastic sewer pipes: through a special glue or by welding.

Methods connection of sewer pipes

adhesive mounting sewer pipes made of plastic:

1. Cut the ends of the pipes, in excess of the dimensions required for installation.
2. Clipped edge treat sandpaper
3. Remove the ends of pipes and connecting elements fat and grease residues.
4. Check the compatibility of the connected pipe sections, they must be combined with a little effort.
5. Put on glue bonding sites.The thicker layer of glue is applied to the connecting element, thinner - actually on the end of the pipe.
6. connected elements of the system, turn the pipe in the connecting member for uniform distribution of the glue.
7. On the outer edge of the connection must be formed adhesive bead consistency of liquid honey.
8. complete drying time of glue and secure the items is about one hour.

Welded pipe laying sewer plastic

1. cropped mountable pipe to the right size, we clean and degreased mating areas.
2. prepares special soldering apparatus and heating it to 260 degrees
3. Fix the connector and the pipe section to the nozzle of the soldering device.
4. Preheat the parts to a temperature indicated in the instructions.
5. Putting heated parts
6. carry out checks on the junction of the absence of backlash, clearances, polymer residues.

Some nuances of the installation of plastic pipe

plastic sewer pipe installation procedure begins with the upper node, ie sewage parts, located at the highest point.It was from her will be calculated slope of plastic pipes for the free flow of wastewater.Sheaths connection elements need to be installed in a direction opposite to the normal flow of fluid.Control the angle of plastic sewer pipes using a spirit level, which has the necessary mark.Also, to control the tilt angle can be exposed and to the marks on the wall.

Often, during the repair of sewerage systems in apartment buildings polymeric plastic pipes have to dock with the old cast-iron.So in the vertical section of sewer system in an apartment building can be with special fittings to insert a segment consisting of a plastic pipe.

is also necessary to remember that the horizontal sections of the sewer system must not be adjacent to the vertical pipes at a right angle.Typically this is done using at least two pipe bends, each of which turns the flow of waste water by 45 degrees.Thus, you reduce the turbulence of wastewater flow and skonstruiruete correct "input" in your sewer obschedomovyh.
