The work is carried out in accordance with SNiP 2.04.01-85 and Federal Law No. 416-FZ “On water supply and sanitation”. We install water supply systems in Moscow and the Moscow region.
A water supply or continuous water supply system is a set of equipment for providing water to civil, industrial buildings or populated areas from special water intake stations. Installation of a water supply system is a complex multi-stage process, including a wide range of different types of work.
The cost of installing a water supply system and installing water supply equipment can be found in the appropriate section.
How to install water supply: choosing a scheme
The routing of water supply pipes can be done in one of two ways.
- The tee method involves connecting all plumbing fixtures in series. On one main pipe, tees are installed in certain places to create branches to household appliances. This method requires less cost, but has a drawback - the water pressure at the extreme points decreases when other consumers are connected.
- The collector method is implemented by connecting several pipes with consumers to a common distribution device - a collector. The method allows you to optimally regulate the pressure in the entire system and perform partial repairs without disconnecting all consumers. To install a collector water supply system, a larger number of pipes will be required.
The wiring diagram should include the following details:
- bathroom dimensions;
- diameter and length of pipe sections used during installation;
- exact installation locations of plumbing fixtures and their sizes;
- installation sites for shut-off valves (taps), filters and meters.
In order to avoid problems when installing plumbing accessories and interior items, it is necessary to draw up a diagram of hidden pipe laying, indicating landmarks and distances. It is also recommended to take photographs.
In order to spend the optimal amount of materials, it is recommended to use the following techniques.
- The collector should be located between the extreme points of connection of plumbing fixtures: this will reduce pipe consumption.
- To connect several consumers to one main line, it is convenient to use tees. Their use also reduces pipe consumption.
The wiring diagram is also necessary in order to correctly calculate the required number of pipes and fittings. Pipes should be purchased with some reserve (10-15%).
Installation of a water heater to a water supply
In autonomous hot water supply systems, flow-through and storage heaters are used. Depending on the pipeline material, different connection technologies are used. Therefore, the services of professionals are always preferable to self-installation. For example, to weld polypropylene and polyethylene pipes you will need a soldering iron or an electrofusion welding device. It is extremely rare in the arsenal of a home craftsman; purchasing it for a one-time connection is not economically justified.
Installing a water heater to the water supply by a specialist has a number of advantages:
- quality - joints will not leak during crimping or sudden increase in pressure during operation
- resource - the master uses high-quality materials and consumables, therefore, the service life increases
- aesthetics - the interior design is not disturbed; if necessary, hidden wiring is used
- profitability - there are no defects, cutting costs, material is purchased in the required quantity with the help of professional consultations
- maintainability - the master has regular practice, therefore, uses connection diagrams, leaving access to the connection points
Free consultations will help you choose equipment in accordance with operating conditions, extend its service life with proper use and maintenance.
Installation of water pipes
In a private cottage in the Moscow region, polymer pipes are more often used, which are a budget option for autonomous/centralized water supply. Despite the simple technology of installing water supply pipes inside the house, the external system is fraught with errors if done independently:
- the home handyman rarely uses a sand bed under the highway
- he forgets about hydro-, thermal insulation of pipes, heating systems
- It is difficult for a non-professional to calculate the power of pumping equipment and select the pipe diameter depending on daily needs
Installation of water supply pipes by professionals allows you to get rid of errors, waste of materials, and use the necessary modifications depending on operating conditions. Our specialists have the necessary tools and experience in using them, therefore, they provide warranties for all work included in the comprehensive service.
Installation of heating cable for water supply
In the Moscow region, as in most regions of the country, heating water supply systems in cold weather is relevant. The heating cable is called self-regulating, however, practice shows that it heats the lines even at a comfortable temperature, therefore, energy costs are increased.
When laying a highway through a site, the owner often uses shallow burial for a number of reasons:
- high groundwater level
- difficult ground/terrain
- passing through the communications section
- high aquifer
In all of the above cases, installing a heating cable for the water supply will save the operating budget. The pipeline will not break due to freezing of the water inside it, and will eliminate the need for excavation work in the winter with a complete replacement of the pipeline and shut-off valves. There is external installation of a heating cable, internal installation of a self-regulating cord.
In the first case, maintainability is sharply reduced - replacement will require digging up the entire pipeline. In the second option, if the economy mode is observed, the service life of the cable can be tripled; its replacement does not involve excavation work. To install a heating cable, it is enough to perform a number of operations:
- buy a cable with maximum heating/cooling cycles
- pass it inside the pipeline or wrap the pipes outside
- measure the temperature in the well/well on the coldest day of winter
- connect a relay to the system, setting its temperature 3 degrees below the measured one
- insulate/insulate the structure
It is recommended to use modifications with a power of 10 W/m for indoor installation, and 17 W/m for outdoor installation. experts recommend relay models TSTAB, TR-35M. The main mistakes of self-installation are:
- use of waterproof insulation - foamed polyethylene is recommended
- relay on one side with the cable - this electrical device is placed on the opposite side
- use of a resistive cable - these modifications operate only at +13? C, therefore, the system will be constantly heated
The user is informed that the cable is connected by a burning LED lamp on the relay. Before backfilling the main, it is necessary to check the functionality of the system.
Types of water pipes
Metal-plastic. They are a thin (0.5 - 2 mm) aluminum pipe, coated with polyethylene inside and out. The polyethylene is attached to an aluminum backing using adhesive. The service life of metal-plastic pipes for water supply is at least 50 years. They are easy to install, do not corrode, and retain their shape when bent.
Polypropylene. Water pipes have optimal sanitary and hygienic properties and are resistant to corrosion and aggressive environments. They are simple and reinforced (with fiberglass or with an aluminum layer). The former are used for cold water, the latter for hot water. The service life of pipes for cold water supply is 30–50 years, for hot water supply – 25 years.
Polyethylene (made of cross-linked polyethylene). They are made from dense polyethylene, so they are flexible and lightweight. Pipes made of cross-linked polyethylene have low thermal conductivity, are frost-resistant, and non-toxic. They are easy to cut, so their installation is simple. Polyethylene pipes are designed for use in water temperatures between 0° and 40° degrees.
Copper. One of the most expensive options for water supply pipes. This type is resistant to high temperatures and pressures. Copper pipes are not afraid of ultraviolet radiation and have a low rate of thermal expansion, but are susceptible to oxidation over time. Installation of this type of pipe is more complicated compared to other types. The service life of copper products in water supply systems is more than 60 years.
Pipe laying methods
There are two ways to lay pipes:
- external installation;
- hidden gasket (in grooves and boxes).
Hidden gasket looks aesthetically attractive, but requires a significant investment of time and labor.
External installation is carried out after finishing work. This installation method requires less time. In addition, exposed pipes can be easily repaired or replaced if necessary. The leak will be detected in time.
Pumps for water supply in an apartment: how to install
In some cases it is necessary to install a pressure booster pump. For the operation of a washing machine or geyser, it is important that the water pressure at the inlet is not lower than a certain value. But if the water does not reach the consumer, you should seek help from an organization that services in-house utilities. If everything remains unchanged, you cannot do without auxiliary equipment.
The pressure booster pump should be installed in front of a household appliance that is demanding of this parameter. It should be remembered that while the pump is running, the water pressure of the neighbors in the riser decreases. In this regard, the use of the pump is allowed only for a short time.
In conclusion, we suggest you watch a video about installing water pipes in a bathroom.
