What you need to know about the elements and the plumbing scheme when conducting communications in the house

When building communications, and especially plumbing, it is necessary to clearly understand the scheme according to which they will pass and where and how certain plumbing fixtures will be located and installed. The presence of a pre-designed scheme will help you in choosing the necessary materials, as it will be clearly visible what footage of pipes and other plumbing fixtures will be needed.
In our article, we will talk about what are the schemes of plumbing systems for water supply of residential premises and related elements to them. /wp-content/uploads/2017/01/358.jpg” alt=”What you need to know about elements and plumbing” width=”279″ height=”315″ />

So, initially a few words about the general: water conduits serve to transport water from sources to a water supply facility. They are two or more pipelines parallel to each other. To supply water to industrial enterprises, residential buildings and other places of consumption, an external water supply system is equipped. The flow of water to the points of water intake (i.e., the distribution of cold and hot water around the house) inside the building is carried out through an internal water supply.

The internal plumbing scheme consists of the following elements:

  • inlet through which water flows from external networks directly to the consumer
  • usually water meter elements (water meters).
  • together with the meters, shut-off valves are installed that control the flow of water
  • after installing the above equipment, it is possible to supply the water supply with a water purification filter
  • also, special reducers are installed in the water supply system conducted to residential apartments, which allow you to avoid pressure drops. These measures are necessary to prevent possible pipe breaks at the joints due to pressure drops in the plumbing system
  • The installation of other elements of the water supply depends on the applied water distribution scheme.

Plumbing schemes are:

  • Dead-end (branched) circuit – circuit A

It consists of a main line and branches that depart in the form of dead ends. In a dead-end network, water flows in one direction – to the end of the branch. The dead-end circuit is the shortest in length, but less reliable with respect to uninterrupted water supply. During an accident on one section of the highway, all sections that are located behind it will not be provided with water supply. Based on this, we can say that the advantage of such a system is that a minimum number of water pipes is required. And the disadvantage is that any breakdown in the section of the highway leaves subsequent branches without water.

  • Ring (closed) scheme – scheme B

In such a water supply network there are no dead ends and all its branches are interconnected and closed. Water in such a system circulates around the ring and breakdowns in one of the sections will not affect the others.

  • Combination circuit – circuit B

This network includes the previous two, consists of looped and dead-end lines. Ring and combined schemes of water supply networks are more reliable in operation. In a looped network, water does not stagnate, but constantly circulates. Emergency sections are turned off without stopping the supply of water to other consumers.

The construction of water supply network schemes must be associated with the vertical and horizontal axes (land planning), as well as take into account other communications, taking into account other underground engineering networks. The water supply routes must intersect at right angles, and the routes must be located so that there is access to other networks and communications.
For example, water supply networks on driveways are laid straight and parallel to the building line, strictly along the highway. Crossings of pipelines must be carried out at right angles to each other and to the axis of the passages. The placement of water lines in relation to other underground utilities should ensure the possibility of installing networks and prevent washing out of foundations in case of damage to the water supply.

The distance in the plan from water supply networks to parallel buildings and structures must be determined depending on the structures of the foundations of buildings, their depth, diameter and characteristics of networks, water pressure in them, etc.
