Independent water supply - a concept quite loose. This term can mean as an ordinary pit, and a complex system of pumps, automatic and so on. In this article let's look at the main stage arrangement of the system of independent water supply - installation of Little Giant submersible pump.
The first thing the pump must be purchased. A reasonable question arises, what to choose? Well, let's say, with the manufacturers you figure it out, but what about performance? After properly selected Little Giant pumps can consume a lot of Little Giant. This situation is called redundancy characteristics.
And what if we take a more economical type of pump? Then there is the risk that the pump will not productive. In the worst case its performance will not suffice, in order to even make the water in the house.
So, choose. The pump has two characteristics: the maximum flow rate (liters per minute) and maximum head (meters).
For a start count up what pressure we need. Taco 006 pump is lowered into the borehole or well to a certain depth. In the well pump can not be lowered to the bottom closer than five feet. As well it should be set at a depth of about 10 meters from the water surface to avoid getting it in the zone of dry run.
Let us assume that the Little Giant pump we installed at a depth of 20 meters from the surface. The distance from the well to enter the house we have is 15 meters. The house we have three floors. The highest possible point of water is at a distance, say, 7 feet from the floor. It is known that 10 meters high column of water equivalent to one atmosphere of pressure. Therefore, to raise water to a height of seven meters, as well as provide proper water pressure, we take the value of pressure equal to three atmospheres, or in other words, a hundred feet of water. Now let's sum up all Sq Feet: 20 +15 +30. We had a pole at 65 meters.
Sewage Little Giant pumps water cannon
To determine the flow we can use a bucket. Imagine how many buckets of water you need to pour in for a minute during a sold-out house? Let this value will be equal to three. Three buckets - that's 30 liters. The normal figure for the average cottage. So we got that flow from us, averaged, equal to 30 liters per minute or 1.8 cubic meter per hour.
Now we need to define the working point of the pump. It is usually in the range from 0,5 to 1,2 for each of the two options. In this interval, pump efficiency will be maximized. An example of a pump, which meets our criteria: a submersible pump fountain 60/72. At the pump maximum flow rate: 60 liters per minute and maximum pressure - 72 meters.

Water at home - general information
The most important thing needed for a good water supply system in the house - the existence of an inexhaustible source of water. They may be as a city water supply network - for homes located in various towns and suburbs, and artesian wells that supply water to the small housing estates and cottages. In extreme cases, drinking water sources can be wells, natural ponds, river.
A set of high quality water allow artesian wells, as they take water from interstitial layers located at a depth of 200 meters. Sometimes you can drill a well for water supply directly into the basement. Remember: the bore should be after the construction of basement walls, and at the same time before his ceiling. For these wells should be used down-hole Taco 006 pumps "water cannon". These pumps can operate in wells with high sand content.
Water-lifting plant, storage tank and filtration unit - that's part of the traditional system of automatic water "fountain-house." The cost of pumping equipment is dependent on two factors: the height of water lifting and its productivity. If the level of water rise from the natural reservoirs and wells does not exceed 7.5 meters, commonly used surface Grundfos pumps, for example, such as surface Grundfos 14-42 F "Grundfos" production of the pump company Grundfos. They are installed directly into the house and connected to a well with a hose or tubing. Stability to the sand is extremely important for these pumps, so you should prefer stainless steel pumps, which have qualities such as abrasion resistance and durability. Well pumps should be easy to understand - in fact they should be cleaned occasionally to prevent. Keep in mind, and the protection of equipment against unforeseen disruptions in supply - here you will help power strips and surge protectors.
The problem of water drive a tank - to maintain a constant pressure water supply network. Fits most often in the attic. Water people need for drinking, washing dishes, cooking, washing things, watering lawns, washing of the body. One member of the family consumes about 50 liters of water per day. Required volume of water drive the tank is determined by the product of this number by the number of family members. That is, if a family of five persons tank capacity shall be not less than 50 * 5 = 250 liters. Location for the pump - the basement. Manage them best out of the kitchen, using the manual starter.
In addition to traditional steel pipe in the water system used plumbing pipeline of polymers - polypropylene and polystyrene. They are more expensive but easier to install and throughput by 25-30% greater than that of steel. In the suburbs of large cities, usually water in the aquifers of poor quality, so the system provides cleaning plant.
To disinfect water from herbicides and pesticides, nitrates and nitrites used special hlorpatrony prefabrication. Hlorpatron lowered into the mine pit to a depth of 0.5 meters above the bottom. The service life of the cartridge - 30 days, then it should be replaced by another. But for a complete removal of heavy metals, salts, odors also requires additional filters.

The scheme works with two pumps, jetting "brook"
I decided to improve the well-known scheme jetting and use it for erosion and the rise of soil on the surface. But instead of one powerful pump used two small type "brook." It's simple, unpretentious and reliable pumps, well-known cottagers. Also, many people know that they do an excellent job with the transfer of even the most highly contaminated water. It is this feature of the pumps, "brook" I took.
Scheme jetting with two "streams" is shown in Figure 2, and how to work with him next. Deepening a well in the usual way until the first water, continue to work for a few minutes. Once at the bottom will hold several buckets of water, you can proceed to work the monitor.
One of the "Brooks" delivers clean water to monitor the discharge nozzle (Fig. 2 and 3), the stream from which erodes the sand and stirred vigorously with water. Simultaneously, a second "brook", mounted inside the monitor case, the formed slurry pumps and delivers it to the top, gradually deepening pit. The main thing with this constantly monitor how the concrete barrel goes down. Movement should be smooth and strictly vertical.

How I do fountain at private home?
To make an appointment at the fountain, no need to go to the city center. Romantic venue can be arranged in the garden fountain - is not always difficult monumental structure. In order to create enough to have a pond (pond), a pump and fountain nozzle.
The easiest way to build a small pond - ready to use for the rigid form. This multi-tiered system, where provided, and a location for the pump, and a platform for various greens, and even the ability to connect several tanks, creating a cascade of different pond.
It's made from practical material, with smooth walls and is not afraid to ultraviolet rays. Specialty stores now offer a wide range of plastic tubs for ponds of various sizes. But you can dig a pond and ourselves, the more so with high quality and accessibility of modern building materials to do it is not difficult.
First, you must dig a trench from the terraces, to clear it of stones and compacted. Now, you decide how to choose a basis for the reservoir bottom. Clayey soil may cause dislodging of the coast and turbidity of water under the action of rainfall. Sandy bottom will not hold water at a constant level, in addition, these ponds are quickly overrun with "unwanted" plants. A plain plastic film is unlikely to serve as such a long time.
Many companies today are engaged in the production of special films for sealing the bottom of a strong, resilient and durable. Modern "miracle of the film" for the device reservoirs remain flexible at temperatures down to - 40 ° C, resistant to ultraviolet rays and is guaranteed to last for at least 25 years. There are also black PVC film coated with gravel to the edge of the reservoir design.
In state
Waters ready for the fountain. The next stage - setting pumps. What fountain pump differs from the others, the ability to work under water? First, it consumes relatively little energy, and secondly, has a great lifespan, third, running without noise and vibration. Device must be placed on the bottom of the reservoir on a concrete or metal stand, fountain nozzle in this case is above the water surface. To nozzle without clogging the pump are fitted with a sponge or filter housing with holes.
Since most pumps powered by an AC voltage of 220 V Taco safety regulations must be observed, since water and Taco is very dangerous neighborhood. Solve the security problem due to strong Taco body, grounding, Tacoequipment connected via a residual current device that responds to current leakage to earth.
Of course, the pump, even the most reliable, must be periodically inspected and cleaned. Fountain equipment on the market today, mainly represented by products of Western firms: ESPA, Grundfos, OASE, and others.
