How to flush a well with your own hands: detailed recommendations


how to flush a well

In cas­es where a cen­tral­ized water sup­ply is not avail­able, a water well is an excel­lent alter­na­tive. This is a con­stant­ly avail­able source of water, both for irri­ga­tion of the site and for domes­tic needs. How­ev­er, some­times the well can become clogged and stop work­ing.

The rea­son for this may be the ini­tial incor­rect instal­la­tion of the equip­ment, so only a well workover can help. But, much more often this hap­pens due to a sim­ple block­age caused by rare use. Some, in such cas­es, call spe­cial­ists, but their ser­vices are expen­sive. How­ev­er, it is quite pos­si­ble to deal with the block­age with your own hands, espe­cial­ly since it does not require spe­cial skills.

Causes of water clogging

Causes of water well blockageOne of the most com­mon caus­es of clog­ging is the irreg­u­lar use of the well. This is espe­cial­ly true for those who use this source of water only in spring and sum­mer, and live in the city dur­ing the autumn and win­ter months. Dur­ing down­time, sed­i­ment from par­ti­cles of rust, silt and sand accu­mu­lates at the bot­tom, which clogs the fil­ters.

The sec­ond most com­mon cause is exter­nal pol­lu­tion. Debris gets into the well­head, edges crum­ble and oth­er fac­tors.

In third place are two pos­si­ble caus­es of clog­ging at once. One of them is a fil­ter small­er than the size of the pipe. In this case, the pump can­not be low­ered to the required lev­el and the fil­ter grad­u­al­ly becomes clogged. A sim­i­lar sit­u­a­tion can be observed when using rotary pumps, which can sup­ply water from a depth of no more than eight meters.

Well cleaning options

There are sev­er­al main ways to clean the well, each has its pros and cons.

  • Using a con­ven­tion­al vibra­tion pump is the eas­i­est way, but it can lead to pre­ma­ture wear of the device. This is due to sand par­ti­cles, which can sig­nif­i­cant­ly reduce the life of the pis­ton and shut­off valve.
  • Clean­ing the well with a bail­er is the most time-con­sum­ing method, but it guar­an­tees good results.
  • Swing Clean­ing — Requires two pumps, so this method is the most expen­sive.
  • Using an air­lift — the method con­sists in clean­ing the bar­rel with com­pressed air.

Cleaning and disinfection with acids

It is believed that the best way to clean the water well is with the help of chem­i­cals. The most pop­u­lar are var­i­ous acids, such as hydrochlo­ric acid solu­tion.

How­ev­er, self-clean­ing a well with such sub­stances is not an easy task. The fact is that with­out spe­cial train­ing, such actions can dam­age the equip­ment, as well as harm your health. Also, not the last role is played by the fact that get­ting enough of the right acid is not the eas­i­est thing. There­fore, wash­ing with chem­i­cals is the lot of pro­fes­sion­als. The meth­ods pre­sent­ed below are no less effec­tive, but do not require spe­cial skills.

Cleaning a well with a pump with a lower intake

pump kidThis method, which is known as well ream­ing, is usu­al­ly applied imme­di­ate­ly after drilling is com­plet­ed. How­ev­er, it is also well suit­ed for sub­se­quent clean­ing.

If you have a drainage or fecal pump, then the process of clean­ing the well is great­ly sim­pli­fied. These devices are espe­cial­ly good because they can pass frac­tions up to three cen­time­ters long through them­selves. For clean­ing you will need:

  • Pump.
  • Injec­tion hose.
  • Cable.

A small met­al rod or brack­et, secure­ly fixed to the bot­tom of the device, will be a good help — they will break dense lay­ers of pol­lu­tion.

You should act in this order:

  • Mount­ed on a cable (prefer­ably steel), the pump goes down until it touch­es the pol­lu­tion.
  • The pump is con­nect­ed to the pow­er sup­ply.
  • Slight­ly shake the pump up and down to loosen the sed­i­ment.

An indi­ca­tor that the block­age is being cleared will be the flow of water with mud and silt sup­plied by the pump.

If there is no appa­ra­tus with a low­er intake, and the well is shal­low, you can get by with a con­ven­tion­al vibra­tion pump, such as the “baby”, to which the pump is con­nect­ed.

In this case, it is to the pump that the impromp­tu “bak­ing pow­der” will be attached.

The pro­ce­dure is the same as above. It is worth not­ing that the device must be con­stant­ly in the water so as not to over­heat.

It is also very impor­tant not to let go of the cable and mon­i­tor its ten­sion. It is not uncom­mon for sand accu­mu­lat­ed at the bot­tom of the trunk to turn into quick­sand. As a result, the sur­prised own­er dis­cov­ers that the pump is stuck in the well.

Well flushing with two pumps

Clean­ing wells with the help of two devices is quite expen­sive, but it is high­ly effi­cient. In addi­tion, it works by wash­ing away sand and silt par­ti­cles. You will need:

  • Bar­rel for water, vol­ume not less than two hun­dred liters.
  • A buck­et with small holes drilled into it.
  • Sub­mersible and cen­trifu­gal pumps.
  • Two hoses.
  • A cou­ple of pieces of rein­force­ment.
  • Clamps.
  • Cable.

The pro­ce­dure is as fol­lows:

  1. The sub­mersible pump is low­ered down and fixed at a height of about fifty cen­time­ters above the block­age.
  2. The dis­charge hose is low­ered into the bar­rel, after which it is filled with water to the very top.
  3. A buck­et with holes is installed in the bar­rel, and a cen­trifu­gal pump is already in it.
  4. On the dis­charge hose of the cen­trifu­gal pump, with the help of clamps, pins from the fit­tings are installed. It is nec­es­sary that they pro­trude ten to twen­ty cen­time­ters beyond the edge of the hose. After that, the hose, with an impromp­tu bak­ing pow­der, sinks to the bot­tom.
  5. Both devices must be turned on, and the hose with fit­tings must be rocked up and down. At the same time, the block­age will be cleared due to the pres­sure of water and the mechan­i­cal destruc­tion of the result­ing plug.

Scheme of water purification with pumping

It is worth mon­i­tor­ing the water lev­el in the bar­rel, for which peri­od­i­cal­ly turn off or turn on one of the pumps.

Using an Airlift for Flushing

The principle of operation of the airliftThis method of remov­ing block­age is to use the so-called “air­lift”, from the Eng­lish “air lift”, that is, “air lift”. It works due to the fact that water, with the help of air, begins to flow upward, and this draws sand and silt from the bot­tom.

For such clean­ing you will need:

  • Air com­pres­sor twelve atmos­pheres.
  • Water in large quan­ti­ties to cre­ate the nec­es­sary pres­sure.
  • Met­al pipe, six cen­time­ters in diam­e­ter and one meter long. In it, at a dis­tance of 25 cen­time­ters from one edge, an out­let for the duct is installed.
  • air hose.
  • water hose.

The prin­ci­ple of the air­lift: water with the help of air goes up, drag­ging sand and silt with it.

The pro­ce­dure is as fol­lows:

  1. The air hose is attached to the com­pres­sor and to the out­let.
  2. The sec­ond hose is fixed at the oppo­site end of the pipe.
  3. This design descends into the low­er part of the trunk, plung­ing sev­er­al cen­time­ters into the silt. It is very impor­tant that the end with the duct is point­ing down and not up.
  4. The sec­ond hose is brought out.
  5. After that, the well should be filled with water and main­tain its lev­el in order to cre­ate the nec­es­sary pres­sure.

After turn­ing on the com­pres­sor, water will be cir­cu­lat­ed, which will wash out the silt and sand. As a result, the dirt will be brought out.

Removing blockage with a bailer

Clean­ing wells in this way is one of the sim­plest, you only need a bail­er and a steel cable. How­ev­er, it requires sig­nif­i­cant phys­i­cal effort — this is man­u­al labor.

The bail­er is a spe­cial tool designed specif­i­cal­ly for clean­ing and you can eas­i­ly buy it. Although, if desired, it can be made by hand, since there are many vari­a­tions of this device.

Clean­ing the bail­er requires con­sid­er­able phys­i­cal effort. This is man­u­al monot­o­nous work.

Below is one of the most enter­tain­ing and endur­ing exam­ples:

  1. You need to take a piece of pipe, six­ty cen­time­ters long.
  2. Inside the pipe, near its end, a disk is weld­ed, in which there should be a hole with a diam­e­ter two times small­er than the diam­e­ter of the pipe itself.
  3. At this end of the pipe, teeth are cut that will break the block­age.
  4. A met­al ball is placed in the pipe, with a diam­e­ter of three quar­ters of the diam­e­ter of the pipe.
  5. A met­al mesh is weld­ed on top of the pipe.
  6. A han­dle is installed to which the cable will be attached.

Bailer - internal device

After that, the bail­er is fixed on a cable and low­ered into the well­bore. Then comes the time of monot­o­nous work — it is nec­es­sary to lift and throw down the bail­er, peri­od­i­cal­ly pulling it up and clean­ing it from the accu­mu­lat­ed dirt inside.

Clean­ing occurs due to the fact that dur­ing the descent, the met­al ball will fall a lit­tle more slow­ly. Thus, dirt, along with water, will have time to pen­e­trate inside the pipe before the ball clos­es the hole.

Prices for work and materials

Con­sid­er the approx­i­mate cost of the mate­ri­als that we need. In almost all cas­es, you will need a met­al cable, which costs about two thou­sand rubles per coil:

  • A drainage pump with a low­er water intake costs an order of mag­ni­tude six­teen thou­sand rubles.
  • The cen­trifu­gal pump costs about sev­en thou­sand rublesand vibrat­ing in the area two thou­sand. A bar­rel of water will cost the amount, from six hun­dred to a thou­sand rubles.
  • The com­pres­sor will cost no more than six thou­sand rubles. The pipe will cost 200–3 dol­lars.
  • Already fin­ished bail­er is in the range from ten to twen­ty thou­sand rubles. Man­u­al pro­duc­tion, with tools, will cost three thou­sand rubles. Or, only at the price of elec­tric­i­ty, since there are man­u­fac­tur­ing meth­ods that require only a drill. Pipes, if desired, can also be found old, as long as they are strong enough.


All these meth­ods are quite sim­ple and do not require large finances — almost always the nec­es­sary tools are at hand. More­over, it will cost much less, not to men­tion the time that will have to be spent wait­ing for repair­men.

It is almost always pos­si­ble to deal with the block­age on your own and for this you do not need to call spe­cial­ists. How­ev­er, you need to be care­ful, because repair­ing wells is an expen­sive plea­sure.
