for use in residential and office premises used several types of water mains:
internal fire water (ERW) serves as a water source for the emergency fire-fighting indoors.Designing this type of construction is regulated SNIP 2.04.01-85 "Internal water supply and sewerage of buildings".
SVC is of two kinds:
operating rules and technical requirements for this type of equipment are extensive enough and to consider them in detail, you will need a separate publication.We will not do this, because we have other problems.
will try to determine the best options for home communications installation.
for hot and cold water in the house is used mainly metal and plastic pipes, as only such systems have high performance:
For DHW use the form multilayer polymeric product, which is the inner layer of aluminum foil, to put it simply - metal and plastic.
Due to its positive qualities, plastic pipe has a leading place in the selection of materials for plumbing work:
That is why in modern apartments and houses is almost impossible to see the metal water pipes.
This is especially true suburban buildings, which originally in the planning of the construction of communications means the use of plastic products is.Composing aqueduct scheme in the country, taking into account all features of laying and possible water freezing in the winter.And here it should be noted that only the metal pipes do not burst under the pressure of the frozen water, and are able to stay in this state until the heat.
The materials used several types of pipe with the device heating system:
Each of these products can be used for its intended purpose, but if you compare them with each other, we find out that:
In any case, the choice will depend on the environment the use of structures and features of operation.
undoubted favorite of the sewer system are plastic products: poliprolen, polyethylene and PVC.They are ideal for the disposal of waste water due to a number of advantages:
Alternatively, you can purchase a reinforced concrete or ceramic designs.But better not to experiment, because the concrete and ceramics are very fragile and break easily enough.Another thing is polyethylene, which is able to withstand high mechanical loads, and even an earthquake in a few points.
