Toilet tube: characteristics and installation of bypass and

Sewage

Engineering communications at home consist of several systems that, when combined, make it possible for a person to feel comfort in their own housing. Today we will talk about the most "dirty" of them - sewage, but rather about the pipes that take part in it. For example, without sewers it would not have been possible to divert the drains in the right direction, and the toilet pipe protects the room from unpleasant odors.

General information

A funnel pipe is a pipe that connects the sewer riser directly to the atmosphere. This prevents the creation of a vacuum that can occur above the wastewater falling through it, which can serve to release the latter with a characteristic sniffing sound and the unpleasant odors entering the room through an empty siphon.

Tip: if the building has less than 2 floors, today construction standards allow not to use the sewage pipes when installing the sewage system, due to the small one-time volumes of wastewater.

How to close the pipes behind the toilet yourself

Examples of the use of the product:

  1. When it can happen that a one-time drain is completely able to block the cross section of the sewer pipe.

Tip: in a private house, the maximum value of single wastewater is achieved in the case of simultaneous draining of water in the bath and toilet.

  1. The waste pipe O110 mm is designed for toilet bowls, because the diameter of their release is usually 70 mm. Sewage from one sanpribor not able to completely block the riser.
  2. From the bath is usually installed sewer pipe O 50 mm, which gradually passes into the riser O110 mm. Siphon in the bathroom is always less than O 50 mm.
  3. From other devices, for example, sinks of a washstand, one-time drains are very small and cannot significantly influence a situation.

Advice: consider, when there are several sanitary facilities in the house that can be operated at the same time, the volumes of one-time drains change.

When to install a fan pipe

The product must be used when:

  • the house has more than 2 residential levels with its own water supply and sewage;
  • there are sewer risers O50 mm;
  • the building has a swimming pool or other equipment capable of giving large single drains to the waste system;
  • Autonomous sewage system is located near the house.

When installing the product follow two rules:

  • pipe diameter must be equal to or larger than the diameter of the riser (in this case, no restrictions are not allowed), on which it is installed;
  • Place the cap at a distance of 300-500 mm from the roof ridge, so bad smell will evaporate faster.

Product Features

  1. Make products from sewer pipes of the appropriate diameter.
  2. They represent a continuation of the riser and end with the input to the ventilation channel, designed specifically.

Tip: if there is an insufficient number of ventilation channels, the pipe can be led out horizontally through the wall.

  1. By installing the product, it is possible to get rid of the unpleasant smell in the bathroom, if the sewage and ventilation are working properly. This is due to the fact that the siphons of modern sanitary instruments have a small diameter, therefore, too little water is stored in them (water trap). When the sanitary equipment is not used for a long time, the water dries out, and sewage air easily penetrates the room.
  2. The sewage pipes are vented by the sewage pipes. This happens when climbing a riser into the atmosphere of warm air, when a slight vacuum is created. Because of this, the air masses do not penetrate into the bathroom, but from it through the dried siphon air is partially removed from the room. In a country house, thereby reducing the odor in the bathroom.
  3. Building codes recommend installing in a warm room or warming products. Otherwise, in case of freezing, evaporation will not be sufficiently dispelled. Because of this, in the very first year of operation, the tube ends will be covered with a sticky greenish bloom.
Types of sewage drainage products

Tip: we recommend installing a check valve on the funnel pipe, which will not allow feces to get back into the house if the sewer system is blocked.

Installation

Below is a detailed instruction, which will be considered in detail the installation of equipment:

Dismantling
  1. Consultation with experts and clarify whether the strength of the system is not compromised if you replace part of it with plastic.
  2. Disconnect the riser and disconnect the structural elements in series.
  3. Use your own hands to dismantle the old sewer system. Cast iron products are now considered obsolete, we recommend replacing them with plastic, being careful. The metal is much heavier than the polymer, and its price is significantly higher.
Installation
  1. Installation of a new fun pipe starts from the lower point of rigidity, which is located in the main riser. In a country house - from the beginning of the foundation.
  2. Then drill holes in the supporting structures, install the product and fasten it with clamps.
  3. Bring the fan outlet to the installed plumbing.
  4. When connecting a flexible sewer sewer pipe to other products, lubricate the O-rings with silicone or liquid soap to facilitate their entry. The first option is better to seal the connection.
  5. When installing, use only metal clamps, they are more reliable and give the opportunity to choose the deviation from the marking lines during assembly. They have a metal stud, which makes it possible to adjust the elements to be joined.
  6. Make noise insulation using a mineral plate or foam.

Conclusion

You do not want unpleasant sewage odors to enter your bathroom, which means you need to install a funnel pipe. Its installation can be carried out independently, after consulting with experts. The video in this article will provide an opportunity to find additional information on the above topic.
