How to choose the diameter of the sewer pipes Housing

Even people absolutely far from all the nasty technical issues related to the withdrawal of products the ability to live, sometimes forced to ask this sacramental question.When drainage is not working, too late to look for "scapegoats" and remake the entire system.For people who have decided to build a similar network of engineering their own hands, give a short course "young soldier".

How to choose the diameter of the sewer pipes Housing

  1. diameter sewer pipes is determined by the maximum flow rate of the slip stream.On the fingers, it looks like.Constantly live in the house three people every weekend comes the cheerful company and all the drains get clogged.The minimum diameter of the sewer pipe should provide all these holidays.The choice of material
  2. sewer pipes is of paramount importance: visualize yourself as you picks open cast iron pipe with a rigid fixation of joints or elegantly changing portion deformed plastic pipe.
  3. SNIP if you install a standalone system can be neglected, it is sufficient to put the right slopes with a gravity sewer sufficient working section.

What's better not to do when laying sewage

you can, using the ready-made tables having recommendatory character, determine the diameter of the sewer pipe and slope (for example, the parameters for a bath and 40 mm 1:30washing - 30-40 and 1:36).Clarity appeared?No, then simply take the sewer pipe polypropylene brown (not gray) color 50 mm in diameter and output it to a septic tank, the aeration fields or just the nearest gutter.What we do not forget:

What

  • bias : non-pressure sewerage scheme O wastewater can operate at angles of inclination of the segments at least 2-4 degrees, ie,meter section of PVC and other plastic pipe with a diameter of 50 need tilt 30 mm;
  • simple design: the fewer bends, tees and other potential dead space you create in your the sewer system (with equal outer and inner diameters), the more reliable the sewage will go out of your home;
  • reliability docking ports : plastic pipes, even in the best industrial designs (Pragma KORSIS et al.) Have insufficient mechanical rigidity;any ground shifts can disrupt connections are tight;
  • calculation angle bends : little problem that can be solved without the involvement of experts;the smaller the radius of the corner elements of any piping system, so it is industrious (in the sewer is an important factor).

What

What is the diameter of the sewer pipe to choose

simple review of the proposals on the market you can fix the PVC pipe pressureless rastrubovaya, perfectly suited to the conditions of an autonomous sewer system of a country house, sold at a price of 180 rubles apiece.Marking of plastic pipe products can be given in metric (40, 50, 75) or inch system (¼ of 1, 1 ½, 2 ½).Choose native millimeters, at least you will know what to buy.

What is the diameter of the sewer pipe to choose

Options productive performance of sewer pipes made of PVC (polyvinyl chloride), PP (polypropylene) and PE (polyethylene), only two:

  • outer corrugation provides rigidity and an inner chemically neutral liner in the composite performance of the same material;
  • sleek version of the plastic pipe, the operating parameters which determine its inner diameter.

Obviously, the external dimensions will be required for excavation, and the inner diameter of the sewer pipe will be responsible for its effectiveness.There are doubts, refer to GOST 22689-89 and SNiP 2.04.01-85.
