What is the adapter to the well, he is better than the box and how to choose the right? With experience in this business, I was just in front of the technical aspects and step sign for how to install the adapter by hand.

Adapter for well design comfortable and unpretentious.

Problem of choice

Before we go into detail, I will briefly tell you what kind of a miracle - Adapter for wells and why do we need it.

This kind of an adapter which is fastened inside the casing. From the deep well pump goes up the conduit and to not mount an expensive caisson, the pipe can be derived under the ground, just for this purpose and serves as an adapter.

How is the adapter wells.

Remember the well adapter must be installed just below the level of soil freezing. The fact that the metal unit and the water in it freezes very quickly.

How does the adapter

The structure itself consists of two parts: the outer and inner:

The outer part It cuts into the wall of the casing through a gasket and clamped by a nut. On the inner side of the tube is tapered on its vertical "skids", to which the second part is put on the structure. This connection method is also called "dove-tail";
The inner part of the adapter - a removable knee, on which a clamp for airtight connection with the slide. Below knee has a thread tap HDPE pipe, and the top thread for mounting bracket.

adapter configurations may be different, but the principle of action everywhere one.

Material for the manufacture of

illustrations	recommendations
	Bronze. One of the most expensive and high-quality materials in the lineup. The warranty on them is around 25-30 years, but they can serve more.
	Brass. Brass quality is considered below bronze, manufacturers promise that hold this assembly of at least 10-15 years.
	food alloys. So-called DZR alloys is typically brass and bronze. It should be relatively expensive to serve 20 years. Under the guise of such alloys can now be selling cheap silumin, visually they do not differ, but "see through" a forgery can be by weight, silumin easy.
	Stainless steel. Stainless steel is perhaps the most high-strength material. The quality is excellent, but the price for such adapters are not less than bronze. It also found a fake, if you take the steel adapter, it is only from a reputable manufacturer, for example from the «Baker».

Caisson or adapter

Drill a well on the site is only half the battle, it is important to properly equip. And here is a dilemma: which is better caisson or adapter? Let us compare the main points for and against.

Headroom to be installed in the caisson is also equipped with an adapter, but the design it is different.

Adapter for wells	Caisson
cost of.
When installed their own hands will be a maximum of 5,000 rubles. If you hire professionals, then from 7000 to 9000 rubles. will have to pay for the work. Total maximum 14tys. rub.	Independent installation will cost 7-25 thousand. rub. Services invited masters 7-10 thousand. rub. Total maximum of 35 thousand. rub.
The complexity of the work.
Drill a hole in the pipe and fix the adapter will even the layman.	Here you need to dig a fairly wide pit, concrete foundation, insert and fasten the concrete rings, plus a well-set head part, which is also not easy.
Time investment.
At the very sidebar, it will take a maximum of an hour, plus excavation and the connection may take a couple of days.	Only on the arrangement of the box body will take at least 3-4 days. To this we must add the trenching and installation tip, that will take another 2-3 days.
The distance from the well to the house.
According to the rules this distance should not exceed 5 m. Otherwise it is necessary to take powerful and therefore expensive subsurface pump. This pump will be hard to find the diameter of the casing, because there is already an adapter.	The caisson is enough space to set the normal pumping station and pumping water to a distance of 50 m from the house.
Dimensions.
The adapter can be put in your pocket and take anywhere, and after the installation, all covered with soil.	For the delivery of concrete rings, plastic, or metal of the box you have to hire transport, plus a portion of the well will take place.
Tightness.
It provides full tightness of the joint.	With an increase in the level of groundwater wells can fill, and therefore, it is necessary to spend money on additional waterproofing or equip drainage.
Maintenance.
Every 2-3 years you will have to dig a connecting node to replace the pads. Plus for such a long time loaded compound "dovetail" can stick and rip it will be hard.	Make prevention equipment installed in the caisson not be easy.

Expansion adapter to save photos from problems with the selection of a deep well pump.

Subsurface pump to peacefully entered into the well, not clinging to the adapter, mounting casing tube below the adapter to install expansion adapter and then install a larger pipe diameter.

How is the adapter

Installing a borehole adapter with their hands should be carried out in a complex, that is not necessary to embed the adapter, and then go buy the pump, everything should be ready. The only thing that can be done in advance, it is to dig a trench.

illustrations	recommendations
	Tool. Adjustable key or gas; Shovel; Round bimetallic crown; Electric drill; Mounting bracket length of about 2 m (a piece of pipe threaded at the end, the thread must be approached to the inside of the mounting adapter shank).
	materials. Fum-tape; When you install the adapter gasket and other accessories comes with the adapter.
	Mounting depth. In the middle zone Russian soil freezing point is at a depth of about 1 - 1.4 m. Better just to dig a trench from the house to the well, gradually going out to the desired depth.
	The primary assembly. Better to start with the assembly of pump groups: Adapter HDPE pipe; Subsurface pump; The check valve; Steel safety cable.
	equipping wells. Typically, the well head part is mounted on a height of 10-15 cm above the ground, so start with the trimming grinder casing;
	Then we lead cut to perfection;
	Headroom is purchased separately, in the chosen model has a sealed box with terminal board;
	Now we put the well head on the casing and integrated by bolts compress the perimeter;
	Installing the adapter. First, check the equipment. The contact surfaces can be lubricated, but not necessarily, because if the connection is not dense enough, you do not notice, because the water goes back into the well;
	Now insert the bit in a power drill and the drilled hole in the casing;
	Then fasten the mounting bracket to the adapter, it is omitted in the casing and display previously threaded through a slotted opening; To dovetail not disunite and the outer part of the adapter, has not fallen into the well, they need to be inside something to fix, for example, firmly insert a piece of plastic pipe.
	At outputted partubok adapter don first rubber gasket, then its fix the bundled curved washer and only after that the nut cheat;
	Then take a wrench and tightly compress the nut.
	Connect the output to the house. For connecting HDPE pipes going to the house I used brass adapter; He screwed into the adapter hole, but on the thread before it is necessary to wind a few turns of the sealing tape fum;
	Next, attach the nut and compress the HDPE pipe.
	Omit and connected pump. To lower the pump into the well with a power cable and a tether effort 1 little, I used the three, and it was pretty hard;
	When the pump is lowered to the desired depth, prune HDPE pipe;
	After fitting, attach the tube to the interior of the adapter and screw mounting bracket;
	The entire design should not be hung on the adapter, for this is the tether, so vymeryat and fix the cable to the center pole;
	At the center pole has a terminal block, but we did not feel sorry for the power cable and removing the terminal block connected directly to the pump, it is better;
	Now you only have to catch and tightly secure the lid, and then a voltage is applied can be used.

Output

Now it will be easier to select the site, and you can easily connect the adapter to the well with your hands. The video in this article clearly shows the installation of the adapter, but if any questions - write in the comments, I'll try to help.
