Coarse water filter in front of the counter: how to choose


water pipe filter

Tap water enter­ing the dwellings goes through a mul­ti-stage purifi­ca­tion pro­ce­dure and at the out­let meets all the require­ments for it. But when trans­port­ed through pipes over long dis­tances, it again becomes con­t­a­m­i­nat­ed. We are not talk­ing about germs — fresh­ly added chlo­rine kills most of them.

The liq­uid is pol­lut­ed, first of all, by the prod­ucts of oxi­da­tion of the walls of the water­ways, detached pieces of lime scale, as well as soil par­ti­cles, if repairs were car­ried out along the route of the water or the tight­ness was bro­ken by dam­age.

Purpose and principle of operation

What is a filter for?

Coarse fil­ters cre­ate a mechan­i­cal bar­ri­er in the way of com­po­nents not pro­vid­ed for by the stan­dards.

This sim­ple fea­ture improves water qual­i­ty and serves to pre­vent dam­age to water fold­ing units: faucet mix­ers, house­hold appli­ances mech­a­nisms (dish­wash­ers and wash­ing machines), facil­i­tates fur­ther purifi­ca­tion of drink­ing water.

Filter types

All devices exclude the ingress of con­t­a­m­i­nants into the con­sumer water­course. Dif­fer­ences in types pro­vide choice to the buy­er and greater com­pli­ance with vol­umes.


The most com­mon and com­pact type of coarse clean­er, often referred to as a sump clean­er.

It con­sists of two noz­zles — inlet and out­let — and a grid, in front of which there is a reser­voir for col­lect­ing con­t­a­m­i­nants.

  1. In most cas­es, the tank is equipped with a remov­able cov­er for the pos­si­bil­i­ty of remov­ing deposits.. Before clean­ing it, turn off the water sup­ply, drain the dirt from the stor­age tank, and, if pos­si­ble, remove and clean or replace the grid. A sump with a flush­ing sys­tem is the same strain­er with a reser­voir, dur­ing the instal­la­tion of which a bypass sys­tem for sup­ply­ing water in the oppo­site direc­tion is pro­vid­ed. Then you do not need to remove the grid — just direct the flow in the oth­er direc­tion. It is very con­ve­nient if a drainage drain is cre­at­ed into the sew­er sys­tem.
  2. Accord­ing to the con­fig­u­ra­tion, the mesh appa­ra­tus is straight and oblique — the name indi­cates the loca­tion of the sump. Instal­la­tion of a direct fil­ter is only pos­si­ble on a hor­i­zon­tal pipe sec­tion and requires a lit­tle more space below. An oblique clean­er can also be installed ver­ti­cal­ly if the water is sup­plied from above.
  3. Accord­ing to the method of attach­ment to the water sup­ply sys­tem, the devices are flanged and cou­pling. The flange con­nec­tion is used on large diam­e­ter pipes, for exam­ple when installing a pre-fil­ter before enter­ing the sys­tem of an apart­ment build­ing. Cou­pling fas­ten­ers are used on pipes of small­er diam­e­ter, in par­tic­u­lar for devices for indi­vid­ual use. Their instal­la­tion is not dif­fi­cult, it is car­ried out using a wrench and union cou­plings, usu­al­ly includ­ed with the fil­ter.

Cartridge or cartridge

Sta­tion­ary fil­ter type for indoor use. It is a vol­u­met­ric flask, with a replace­able car­tridge through which water pass­es. Elim­i­nates both large and small impu­ri­ties.

Often used as an indi­vid­ual device for water that has under­gone gen­er­al house clean­ing. The replace­ment ele­ment is made of plas­tic (dis­pos­able) or cor­ro­sion-resis­tant met­al (reusable).

The design is attached to the wall, access to the car­tridge is car­ried out using the key includ­ed in the kit.

pressure system

High-speed pres­sure sys­tem for coarse clean­ing: it is an impres­sive flask filled with a clean­ing com­pound, inside which water is fil­tered. Pol­lu­tion from 30 microns is retained.

The sys­tem is equipped with a device that reg­u­lates the com­po­si­tion of water. This type of fil­ter must be con­nect­ed to the sew­er — pol­lu­tion is removed through the drainage drain. Thus, the whole struc­ture is a self-clean­ing device.

The kit includes pres­sure gauges at the inlet and out­let, it is pos­si­ble to reg­u­late the pres­sure inside the sys­tem. Oper­a­tion is pos­si­ble only in a room with a pos­i­tive tem­per­a­ture. Due to the size and cost, it is advis­able to use at the entrance to the house.

How to choose

how the filter worksWhen choos­ing a clean­ing device, one should pro­ceed from the pur­pose of each par­tic­u­lar appa­ra­tus. The coarse fil­ter for indi­vid­ual use has small­er vol­ume indi­ca­tors, and its instal­la­tion and clean­ing is eas­i­er. Devices for apart­ment build­ings and indus­tri­al pur­pos­es are cho­sen by spe­cial­ists.

When buy­ing, you should check the device for vis­i­ble dam­age and cracks — exclude fac­to­ry and ship­ping defects.

Design flaws are a rel­a­tive con­cept. Who is warned is armed. There­fore, in each case, before buy­ing, you should read the instruc­tions for using the mod­el, make inquiries with the sell­er.

Dis­ad­van­tages are revealed, unfor­tu­nate­ly, only dur­ing oper­a­tionbut this does not affect the qual­i­ty of the fil­ter, it only com­pli­cates main­te­nance and oper­a­tion.

Before pur­chas­ing, you need to make sure that the con­fig­u­ra­tion of the mod­el ful­ly com­plies with the declared list in the instruc­tion man­u­al. War­ranties are required. When installing the fil­ter your­self, do not use incom­plete parts and tools if spe­cial fit­tings and keys are includ­ed in the pur­chase.

Installation and maintenance

Instal­la­tion is not dif­fi­cult. Ini­tial instal­la­tion involves cut­ting the pipe and thread­ing, so it is bet­ter to entrust this pro­ce­dure to a plumber or rep­re­sen­ta­tives of account­ing orga­ni­za­tions: usu­al­ly, when installing a meter on water, spe­cial­ists are required to install a coarse fil­ter.

Fur­ther main­te­nance is car­ried out inde­pen­dent­ly. You can unscrew the struc­ture with a wrench, hav­ing pre­vi­ous­ly turned off the water.

It is rec­om­mend­ed to clean the device at least 4 times a year or more often if there are signs of con­t­a­m­i­na­tion: dete­ri­o­ra­tion of the organolep­tic prop­er­ties of water, decrease in jet pres­sure.

Expe­ri­enced plumbers rec­om­mend check­ing the tight­ness of the con­nec­tions every time to pre­vent leaks. It is best to seal the joint with linen tow.

Why is it necessary to install before the counter

A coarse fil­ter must be installed in the pipe sec­tion in front of the water con­sump­tion meter. This will ensure the cor­rect oper­a­tion of the device, pro­tect all devices using water from dam­age.. The use of the device will ensure long-term oper­a­tion of house­hold appli­ances.

Cost and popular models

There is a fair­ly large selec­tion of coarse clean­ing devices on the mar­ket. The most pop­u­lar indi­vid­ual mod­els are mesh sim­ple straight and oblique fil­ters with remov­able revi­sion cov­er. Devel­op­ers, home­own­ers asso­ci­a­tions and man­age­ment com­pa­nies use large sta­tion­ary devices. The cost of the first ones is from 120 rubles, and the pro­fes­sion­al ones fit into the range from 2,000 to 300 dol­lars.

Most res­i­dents of new build­ings are relieved of the need to install an in-house device: when putting the house into oper­a­tion, the pres­ence of a water meter and a fil­ter in front of it is checked. When using plas­tic pipes inside the house, the water is not pol­lut­ed.

And in hous­es put into oper­a­tion many years ago, the use of this type of clean­ing is high­ly rec­om­mend­ed: with many years of use of met­al pipes, cor­ro­sive con­t­a­m­i­na­tion is inevitable. Many reviews say this.

Olga, 26 years old

I have a small child, and I am very atten­tive to the com­po­si­tion of his diet. Before the coarse fil­ter was installed, I was hes­i­tant to use tap water to pre­pare mix­tures. Even after fine clean­ing and boil­ing, there was plaque and sed­i­ment. And the drink­ing water fil­ter clogged very quick­ly. When they put the meter on the water, they also installed a coarse clean­ing device — a small detail on the pipe. The water has become much clean­er.

Anton, 38 years old

In a coun­try house, I have water from a well. Worn for analy­sis in the lab­o­ra­to­ry. Allowed to eat, but only after boil­ing — there are par­ti­cles of soil. There are a lot of appli­ances in the house, from the dish­wash­er to the hot tub, and I real­ized that their longevi­ty depends on the incom­ing water. The pres­sure from the source is good, so I installed a high speed pres­sure fil­ter. Drainage led to the sew­er, now there are no prob­lems with clean­ing — the sys­tem does every­thing by itself. Very sat­is­fied.

Thus, the coarse fil­ter is the imper­a­tive of the times. To save equip­ment, plumb­ing, plumb­ing equip­ment, its instal­la­tion is nec­es­sary. Afford­able price and high effi­cien­cy made these devices in demand among con­sumers.
