How to pump a well after drilling

Those who have not experienced drilling before, may think that the process of installing the pipes ends, but it was not there! In addition to the arrangement and connection to the water supply system, you also need to pump the well, because at first you can only pump out the dirty water. What is this procedure?

What is pumping necessary

Clear water

We give a clear example. If you dig a small hole and pour water into it, what will it resemble? Clearly not a pool with drinking water! Even after the water settles, it still does not become clean, and at the bottom will be visible silt and other debris.

Now imagine what the bottom of the well is after drilling, especially if a back flush method was used, during which a mud solution was fed into the well to strengthen its walls. Want to drink this water? Of course not!

How to pump?

Powerful submersible pump

Let's start with the question: Did the company make a well, or shabashniki? Further actions depend on the answer, since in the first case this service is included in the terms of the contract (if you, out of ignorance, have not refused it). This is done using a powerful submersible centrifugal pump capable of pumping from 3 to 6 m³ / h of water containing a large amount of impurities. Such a pump falls almost to the bottom of the well, and with a powerful suction flow it will pull out all the debris.

But if you “saved” on pumping by hiring workers, the cost of which is less than that of professional drillers, but they don’t answer for anything, you will have to pump the well yourself. To do this, you need to purchase an inexpensive domestic pump.

Do not be in a hurry to say that you do not need it, since an imported one, which is specially purchased for this purpose, is already available. What kind of water will we pump? Almost a swamp with sand and various litter! Therefore, if you hurry to install your expensive branded pump for pumping, then get ready to say goodbye to him, as it is simply not designed for such work.

Returning to an inexpensive domestic pump, which may not even survive until the end of flushing:

1. Attach a stainless steel cable to it, and lower it to the bottom of the well.
2. Then lift the centimeters up by 30-40 and fix in this position. Now you can turn on. Seeing what the water went themselves will be delighted that they did not put an expensive pump.
3. In order for your “Kid” (or “Trickle”) to serve as longer, you need to pull it out from time to time, and give you the opportunity to clean yourself with clean water, and then lower it back into the well.

The pump must not be in the same position. It should be slowly raised and lowered by 4-6 cm, while not making sudden movements. This is necessary so that the sand from the cork is lifted in parts, and does not block the hose.

The pump should be gradually lowered lower and lower in order to clean the bottom of the well from all that is superfluous. If suddenly the water from the hose stops going, then, most likely, the pump is aspirated. In this case, it must be immediately disconnected from the power supply and pulled out, and this would not work without an attached cable, since the silt firmly holds everything that gets into it.

How much to pump?

Layout of aquifers

Relatively shallow well, in which the aquifer consists of sand or limestone, it can be pumped in a day. If the well is deep and the sandstone aquifer, the pumping can last a month! If this is the case with you, then do not rush to think that this well is unsuccessful. Clean water will gradually flow, and such a well can be used up to 50 years.

Errors that should be avoided

Ignorance of some, seemingly elementary issues can make life very difficult. Consider some of them.

• The pump is located near the surface of the water. In this case, it will pump out only water, and clay deposits and sand will remain in the well, constantly polluting the water, or completely blocking its access.
• The pump is located at the very bottom. In this case, it will very quickly fail, clogged with a suspension, or simply "buried" in the mud.
• The cable is not attached to the pump. In this case, it will be impossible to pull it out when stuck in the ground.
• Pumped water is poured near the well. In this case, the water will again flow into the well, washing away its walls fortified with clay. Such pumping can last forever.

Bleeding a well

It is important to remember that well needs maintenance work. If you notice that the water level during the operation of the pump decreases, then you need to turn on the pump every day for 2-3 hours.If this did not help, and the water began to act poorly, then it is necessary to wash it from the sludge formed in it. To do this, lower the hose into the well and pressurize it with clean water. This should be done until all bottom sediments rise up and come out of the well. After that, you need to pump the well again. Only in this way water will always be clean.
