water pipes defined with the required parameters of pipes (wall thickness, diameter) for any water supply scheme, in principle, is simple.Another thing is the material - understand, what from this point of view, pipes for water supply in the house is better to choose.

On the one hand, the choice is simplified, because the requirements for the product, mounted in the cold-water system are not so high as, for example, for the heating circuit.Although, if only because in the water factor of thermal expansion is not critical.But on the other - so big range of pipes (only one species and subspecies, there are more than a dozen) that the average consumer is simply lost.

Before analyzing the pros and cons of the relevant types of pipes, it is useful to clarify on what criteria is primarily oriented "private trader»:

circuit durability.
Possibility of production of all technological operations (such as installation of pipes and, if necessary, repair of water supply system in some areas) on their own.
Easy installation and maintenance.
acceptable cost of production.

Types water pipes in material manufacturing

Steel

metal - tube traditional and well-known to all of us since childhood water pipes.

Advantages

mechanical strength.
Large operational period (on average - about 50 years).

Perhaps this is all the advantages of steel pipes, which can be noted.But more minuses.

Disadvantages

considerable weight of the pipe. Installation of metal water pipe, in some cases associated with certain difficulties, and above all, with the fixation of the pipe walls.If a private house built on frame technology, or of foam, the mounting brackets and will require time and experience.
condensation. Moreover, it will appear on the pipes regularly.Firstly, the water in the cold circuit by definition.Second, the intensity of this process is influenced by the temperature inside the house and its fluctuations outside.Therefore, to completely eliminate the formation of water droplets in the water pipes is almost impossible.And the excess moisture, in addition to a certain discomfort, leading to delamination (peeling) paint on the metal, so you have to regularly update such coverage.
corrosion. minimize its consequences and increase the life of maintenance-free service water pipe can, if you choose the galvanized pipe.But to completely avoid rust development will not succeed.One way or another, but her tiny fraction will fall into the water, so you have to install additional instruments of better water treatment as a "sump" is not enough.
roughness of the walls. It is primarily concerned with the internal cavity of the tube.If the touch is smooth and it seems, that it is not so.Microscopic bulges and indentations - areas where eventually appear foreign deposits.As a result - reduction of water pressure in the private house and interruptions to the work of some appliances (eg boiler).
complexity of working with a metal pipe.If threading and socket joint special difficulties (with the appropriate tools and materials) does not cause, they bend when laying water pipe - is a problem.
risk of leaks from joints. And they eventually will, even if the installation of running water is made by all the rules.

Conclusions

For private homes water steel pipes - not the best option.They can be used only when necessary, replacement of a portion of the track when it is initially laid metal.
If necessary, the installation of steel pipes, galvanized products should be selected.Blanks made of ferrous metals for water - the worst solution.

Copper pipes

honey Such pipes are deprived of most of the shortcomings that characterize steel counterparts.Water supply mounted with copper samples is reliable and durable.A significant advantage - the pipes do not have to constantly touch up, and besides, they are due to the "noble" appearance, organically fit into any decor.The route running water do not even have to hide.But

afford such an arrangement aqueduct can not everyone.The reason - too much spending.Higher financial costs are associated not only with the price of copper, but also with the specific pipe connections..

First , independently, without practical experience, do not get water.We'll have to invite professionals.

Second , for fastening pipes need the burner, a gas cylinder, a special wire.Such equipment to the "household" category does not apply.Purchase it only to mount in a private home circuit HVS, it is hardly advisable.

Conclusion - water from copper pipes in all indicators is the best option for private homes.But only if the owner does not confuse the high costs of its installation.

Metal pipes

The structure of such tubes - composite products.As used metal frame reinforcement member disposed between the plastic layers.Constructional "core" can be performed in different ways: in the form of a helical winding, whole or perforated intermediate level.For all indicators - production cost, ease of installation of running water and a number of others - not a bad option, but not for a private home.There are several reasons.

metal-plastic - pipe

First , if the pipes themselves are relatively cheap, the fittings are quite expensive.

Second , this water requires regular maintenance, mainly because of the need to constantly tighten all connections, which do not differ in strength.

Conclusion - plastic pipes are more suited for laying out at the territory, at their summer cottage.For the installation of cold-water circuit inside the building is better to choose an alternative.

Plastic pipe

PPN This generic name for such pipes as they can be made from PE (polyethylene), PVC (polyvinyl chloride) and PP (polypropylene).Depending on the material there is little difference in the properties of the individual products, but in relation to the water supply differences so insignificant that all their pros and cons can be combined.

pipes Advantages of plastics

Lightweight.
strength combined with elasticity.
Personalising your products, ease of installation of running water.
long period of operation of the pipe.
Reduction of the inner diameter is practically no, as the perfectly smooth surface (inner) do not accumulate any layers.
Plastic pipes do not corrode.

divorce

What to consider when installing plastic pipes:

PVC, according to experts, can give off toxic substances.If the pipes are not from a reputable manufacturer, then there are certain risks.
for bonding products from PP need to "iron" (special welding machine).In addition, they do not bend, so the complex trajectory track the aqueduct will have to make many connections (for example, the corners of rooms).More welding of plastic pipes is described in this manual.
With PE pipe work easier.For running water, it is desirable to use cross-linked polyethylene.Most professionals do not doubt that it is - the best option for private homes.

Pros plastic pipes

inert material to low temperatures, extremes values.Therefore, PE pipes can be installed in the water pipe system inside of a house and outside.
Large strength of the joints.The risk of leakage is practically ruled out.
mounting technology - simple.All pipes are joined fittings, which are crimped special device.

general conclusion

for plumbing in a private home should choose plastic pipe.In terms of practicality the best solution - products of PE (cross-linked).Such pipes are more expensive counterparts from polymers, but these costs, given the specificity of functioning of the system, more than justified.

author gave sufficient "information for reflection", and the particular choice is yours, dear reader.Good luck to install running water!
