Diagnostics and repair of water wells

It is almost always possible to drill a well in your own area, install a pumping station and use free clean water at your discretion. But time plays against any equipment, and you need to be prepared for possible breaks in the plumbing system.

In this article we will consider recommendations for identifying the causes of such troubles and methods of dealing with them.

Diagnostics

It is very important to correctly identify the source of the problem..

Especially if you call a specialist for repairs, the cost of mistakenly determining a breakdown will be quite noticeable.

1. We notice the problem when we open the tap in the house. If the water flows weakly or has a strange shade, then it is likely that the problems are between the mixer and the pump. And then you need to call a plumber.

Tip: in order to make sure that the station itself is in good condition, you can connect a piece of hose directly in place of the plumbing system to it. Under normal pressure, it will become clear that the case is probably in the home plumbing.

1. If the test shows the lack of pressure at the outlet of the pumping station, then the automation of the unit may have failed. In this case, you can help an electrician or a specialist in repairing pumping equipment.

Tip: to test the device with your own hands, you can connect to the outlet pipe of any other pump. His work will confirm the absence of problems in the mine itself.

1. In the case of confirmation of pump serviceability by the method of elimination, only the well itself remains. Drilling and maintenance are usually carried out by the same company, to which should be addressed in this case.

Causes and troubleshooting methods

Part of the restoration work can be completely carried out independently, and we will begin with them.

Silting

The cause of this disease is usually a long idle well.

There are several ways to deal with it:

1. Turn equipment on for a while until clean water is poured. This is the first thing that should be done before taking any radical measures.

Tip: in order to save station filters, it is recommended to use a separate vibration pump for pumping debris from the bottom of the mine.

1. Take advantage of the scythe. This is a kind of metal pipe, in which the top edge is covered with a fine mesh, and the bottom bottom washer. Inside it is a metal ball, and a cable is tied up on top.

Instructions for its use looks like this:

• The device is lowered to the bottom of the mine.
• Raise half a meter and sharply throw down.
• Dirty water is drawn into the inside of the pipe until the lowered ball closes the inlet.
• After 3-4 repetitions we raise the unit to the surface and clean it of garbage.
• We carry out the procedure until the well is completely cleaned.

1. Create a well cleaning system from two pumps. This method is considered the most effective and is suitable for mines of any depth. It is performed as follows:
2. A deep liquid pumping unit is submerged on the bottom.
3. Its outlet pipe leads to a special container, equipped with a fine-grained mesh to filter the contents.
4. Purified water from the reservoir is distilled standing on the surface of the pump back to the bottom of the well.
5. Under the pressure of the incoming liquid, all the garbage rises from the bottom and is thus better absorbed by the first apparatus.

Filter bandwidth reduction

If the pumping station began to shut down frequently due to idling and the pump connection showed a weak head, this means contamination of the lower filtration system of the well.

The reasons for this event:

• Error while drilling. Creating a weak cushion of gravel or hitting the filter in clay soil during installation.
• The presence of extremely fine sand.
• The accumulation of minerals on the filter grid.

Methods for eliminating such a malfunction are accompanied by some risks:

• Water hammer Very effective way to help in all three cases. But at the same time it can damage the filtering structure itself, which cannot be replaced. In this case, will have to drill a new mine.

• Filling special acid. It is also quite an effective method, dissolving all growths and deposits. When applying it, it should be taken into account that for some time the produced water ceases to be potable.
• Shoe ruff. The safest repair option, but less effective.

Capital restoration

The well in sandstone is in most cases cleaned and repaired on its own. Artesian, because of its depth, is much more difficult to maintain, and it is desirable to call specialists with the appropriate equipment.

They can use the following groups of methods for repair:

1. Hydraulic. This includes the use of pumping, water hammer, piston, water washout.
2. Impulse Produced by instantaneous pressure drops in the bottom hole of the mine.
3. Reagent. Treatment of wells with specially selected reagents to clean even the most distant pores while maintaining water quality.
4. Vibration. Erlift pumping using vibro.

Total

The work of the well must be closely monitored and timely carried out maintenance and repair work so that it can continue to please you with an abundance of constant and pure water.
