Adapter for wells : why is it needed and how to instal their own hands

All builders are well aware that any water pipe is laid slightly below the level of soil freezing.Otherwise, during the cold season, the frozen water can break the pipe.To comply with the conditions in the place of running water to the casing connections are usually equipped with a special insulated pit or construct the caisson.This helps protect the pipe from freezing.Some time ago it was invented a device that allows you to avoid all of these structures and to connect water pipe below the frost line.At the same time, the pump can get out of the hole for periodic maintenance without having to dismantle.This adapter well: why is it needed and how to instal their own hands, will understand in this article.

What are the advantages of the well equipment adapter

This device, which is also called pitless-adapter has two parts.One of the details of cuts in the casing at a depth that is necessary to ensure year-round use running water without freezing.From her house is laid water pipes.The second part is on the inner side of the casing pipe and connected to the pump, which is immersed in the well.This adapter makes it possible to place the pump through the casing to the bottom of the well and put all the pieces into a single water without resorting to digging a pit.After that, the whole system becomes fully suitable for year-round operation.

The adapter takes the weight of the entire pump and fully accepts all vibration during operation of the equipment, pipe, into which it is to be crashed into the steel.This does not preclude the possibility of tie-in polypropylene casing of the device, but this option will differ lesser durability.

equipment water well pitless adapter has a significant number of advantages

• Easy installation allows you to carry it out, even an inexperienced person.
• whole set of equipment is not very much that is attractive for the consumer.
• labor charges for installation details are slim.
• There is no need in the construction of the caisson, or pit, which also reduces the costs and expenses.
• Opportunity premises all wells within the soil without displaying the earth's surface.

As already mentioned, the use of the adapter makes it possible to remove the pumps without any problems and put it back after the service.For these purposes, millet disconnect the internal part of the device and pull out the pump.It is only necessary when purchasing equipment directly correlate all pipe sizes, pump and projecting parts of the adapter.The pump must be free to plunge into the hole without touching the adapter.

How to install pitless adapter

Installation downhole adapter does not require any special knowledge and skills.Everything is done simply using the following algorithm:

1. From the house dig up the casing of the well at the required depth.The depth of soil freezing varies by region.In the middle zone, it is a maximum of 1.5 m, although most of this figure is much lower.
2. The pipe drilled hole of the desired diameter.It is equal to the diameter of the main body of the adapter.
3. inserted into the hole of the outer adapter.
4. well set on the lid covering it.
5. attached to the body of water pipe, which is laid along the trench that leads to the house.
6. mate downhole adapter is connected to the hose of the submersible pump.
7. submersible pump is lowered into the well and connect both sides of the adapter.

Installing the main part of the borehole adapter

a closer look at how to implement the installation of the adapter to the casing.Before starting the installation, you must make the correct hole in it.To do this, you need to get a bimetallic crown cutter, which is able to cut a hole with smooth edges in the metal.Its diameter is chosen so that it exactly matches the diameter of the adapter.Thereafter, the pipe is lowered into the second part of the adapter and is introduced into the hole.Outside its fixed ferrule.Both inside and outside of the adapter is put on rubber seals in the form of rings.After that, the two parts are tightened wrench.The pipe from the water supply is connected to the adapter on the outside by a threaded connection, which need to be isolated in order to avoid leakage.

Installation mate

Before you begin installing the mating adapter, you must install the pump correctly.It is lowered to the desired depth and fixed in this position.The pipe or hose from the pump cut and inserted into the mating parts.Even before the start of all this work the pump is best to gather in a room, adding to it a hose, wire and cable.All this brings to the well where the stack on clean space to prevent dirt from entering the well.Thereafter need to take special pipe that is designed to facilitate mounting of the adapter.It is screwed into the hole on the inside of the adapter, designed for it.Thereafter, the tube together with a part of the adapter is placed into the wellbore and connected to both sides of the device.Then, the tube is unscrewed and removed.She need only when you need to get re-pump.

Note that after the removal of the mounting tube can damage the threads on the device by moisture.For this reason, the pipe can not twist, and simply cut flush with the orifice hole, so as not to interfere.

After mounting the adapter to the outside output tether and tightly fix it.This reduces pump hanging from the load on the adapter.At the final stage is fed to the pump power supply and check operation mounted system.Most often downhole adapters made from a strong and corrosion-resistant materials, such as copper or brass.However, once a year the unit should be disassembled and lubricated with special grease.This measure significantly extend the service life of the device, and seals it.

Installation downhole adapter can significantly reduce the cost improvement of water well as eliminates the need for construction of additional structural components for thermal insulation of the pipeline.
