The water supply system has already firmly penetrated the minds and plots of the owners of village houses and country cottages. This is an integral attribute of a comfortable life: with running water, showers, washing dishes, cooking become a pleasant experience.
Installing it yourself is not an easy task, but you can do most of the work alone.
We develop a water supply scheme
In fact, there are plenty of plumbing schemes, but there are two different methods for connecting consumers:
- Trinity inclusion.
- Collector or parallel connection.
For residents of small private houses, a serial connection will meet their requirements, the plan for such water supply is simpler. From the source itself, water in order goes from one consumer to the next from one pipeline with a tee outlet (1 inlet, 2 outlets) for each consumer.
Such a switching scheme is characterized by a lack of pressure at the last consumer, during the launch of the previous ones, if several such links are involved in the chain.
The collector inclusion plan looks fundamentally different.
Firstly, when making such a connection, you will need a collector. From it, a water pipe is laid directly to each consumer. Thereby you will be able to create more or less the same pressure in any link in the pipeline chain. Please note that a serial connection will cost you more.
Any water supply system consists of a well, a pump, a hydraulic accumulator to protect the pump. And if desired, a filter or several filters before or after the accumulator.
There are several types of plumbing pipes, the most common materials for them are polypropylene, polyethylene (crosslinked), steel. The most expensive ones are made of copper, because they last the longest.
In case of mounting them, you will have to call a specialist. The best choice is polypropylene in terms of price-quality ratio. Please note that plastic as a material is absolutely not suitable, as it releases harmful elements into the water.
The diameter of the pipe depends on the length of the pipeline of a private house: from 30 meters, material with a diameter of 25 mm is enough, if more than 30 meters, then 32 mm will do, and in the case when the length is less than 10 meters, the diameter varies within 16–20mm.
Next on the list you will need a submersible pump, as it is more durable and more efficient than a pumping station. The height of the pump is measured along with the hose and then they are connected by a threaded connection. The pump can be placed in any position on stainless steel cables. It hangs from the top of the well.
Water from the pump enters the filter to the accumulator, which is the next element of the circuit. It creates a stable pressure and allows you to turn the pump on and off as needed.. The volume depends on the amount of water consumed.
The water is again filtered and divided into two streams: one of them will go to the boiler and heat up, and the second will remain cold in the collector.
It is necessary to mount shut-off valves up to the collector, as well as install a drain cock.
The pipe going to the water heater is equipped with a fuse, an expansion tank, and a drain valve is also installed. Same the tap is mounted at the outlet of the water heater, and after that the pipe is connected to a collector with hot water and further divorced at all points in the house.
Boilers may vary. Water can be heated by gas or electricity. A gas instantaneous water heater differs from an electric one in that the water is constantly heated.
Plumbing deserves special mention.. The process of connecting the toilet begins with the installation of a corrugated pipe, which is lubricated with silicone at the junction. Next, the reliability of the connection is checked, holes are drilled into which the dowels are inserted. The toilet is attached to the corrugation and twisted.
The water supply from the well is divided into two types: summer and winter:
- Summer view of the system being laid above the ground – rubber hoses are connected with adapters and thus the required length is ensured.
- Winter view of the water supply works in any season and it is laid either below the freezing of the soil, or above, but with insulation.
Before conducting water from the well, it is necessary to make a caisson for it. You can go down into it and it will protect the well from dirty water.
The caisson is made of concrete rings or other materials.. If its bottom and the pipeline are above the freezing of the soil, it does not make sense to use a caisson in the event of a pipe break.
Connecting to the central highway requires a significant investment in the early stages, meanwhile, partially relieving of excavation and installation of a septic tank. You can find out information about the nearest highways in the ZHKO.
To increase the water pressure in the pipeline, it is necessary to embed the pump into a public water supply pipe or install a pumping station with a hydraulic accumulator.
Usually in apartments it is common to mount pipe wiring to the wall.. Sewer pipes are held on clamps attached to the wall. The distance that is measured horizontally from the clamp to the clamp must be set to less than 10 pipe diameters.
You can use either metal clamps with a rubber seal (rigid mount), or without sealing so that the pipes can move freely (rigid-floating mount).
Internal wiring is a more advanced routing methodbecause it reduces noise and looks better. It is possible to lay pipes in concrete or strobe, observing slopes and sealing gaps.
Polypropylene pipes are welded in two ways: socket and butt. It should be carried out at a positive ambient temperature. It is important to remember that pipes and fittings are of the same composition and are clean. Also, do not cool the pipes after connecting with water.
During socket cooking, both parts are heated with a special heating device, then collected and cooled.
Prices for materials and equipment
- A submersible pump with a capacity of 1.7 liters per hour costs 6,7 dollars;
- You can buy a hydraulic accumulator with a volume of 50 liters for 46$;
- Polypropylene pipe 4 m long from 15$;
- An electric water heater is sold at a minimum price of about 10 dollars.
