Do-it-yourself water meter installation: instructions and rules

[ad_1]

A large part of the fam­i­ly bud­get is spent on util­i­ty bills. It is pos­si­ble to sig­nif­i­cant­ly reduce the amount in pay­ments with the help of spe­cial tools that record the real con­sump­tion of resources, whether it be water, gas or heat.

The Gov­ern­ment of the EU strong­ly rec­om­mends doing this, threat­en­ing a sig­nif­i­cant increase in the cost of util­i­ty bills in apart­ments that are not equipped with meter­ing devices. Water meters, unlike oth­er con­trol devices, can be installed inde­pen­dent­ly.

The cost of buy­ing and installing two water meters for hot and cold water will pay off in four months for a fam­i­ly of 3 peo­ple who are not too con­cerned about sav­ings. With a pru­dent approach, the pay­back peri­od can be reduced by almost half.

How to choose a water meter

Exists 4 types of mea­sur­ing instru­ments for water:impulse metering device

  • pulse (elec­tro­mag­net­ic and elec­tron­ic);
  • vor­tex;
  • mechan­i­cal (sub­di­vid­ed into vane, tur­bine and com­bined);
  • ultra­son­ic.

Accord­ing to its pur­pose coun­ters are divid­ed into three types:

  • for hot water;
  • for cold water;
  • uni­ver­sal.

In our coun­try, mechan­i­cal and elec­tron­ic account­ing sys­tems are avail­able and in demand.

Mechan­i­cal counter price varies with­in from 300 to 5 dol­lars. Ser­vice life — up to 12 years.

All these fac­tors, as well as low mea­sure­ment error and sim­ple instal­la­tion, attract buy­ers. The dis­ad­van­tage of these devices is the sen­si­tiv­i­ty to mag­net­ic fields and the com­po­si­tion of water.

mechanical water meters

Elec­tron­ic water meters bet­ter, but cost sev­er­al times more from 800 to 20 dol­lars.

Doubt­less the advan­tages are:

  • mea­sure­ment accu­ra­cy,
  • quick dis­man­tling for inspec­tion,
  • instal­la­tion in hor­i­zon­tal and ver­ti­cal posi­tion,
  • long ser­vice life.

Flaws:

  • high price,
  • the need to main­tain a con­stant pow­er sup­ply to the elec­tron­ic unit.

When buy­ing a device, pay atten­tion to the pack­age and the pres­ence of a prod­uct pass­port. The ser­i­al num­ber on the device must ful­ly match the data in the pass­port. The meter mod­el must be entered in the State Reg­is­ter of Mea­sur­ing Instru­ments of the EU. To avoid trou­ble in the future — buy water meters in spe­cial­ized stores.

The counter must be equipped with:meter equipment

  • check valve,
  • mesh fil­ter,
  • two Amer­i­cans.

Valve will pro­vide a one-way out­flow of water, and fil­ter — saves the meter from pol­lu­tionthere­by extend­ing the life of the device.

Stop­cock you will need to buy with a steel han­dle. Its cost is 300 — 6 dol­larsdepend­ing on the man­u­fac­tur­er.

Installing a water meter yourself

Instrument preparation and installation site selection

Toolrequired for water meter instal­la­tion:mounting tools

  • scis­sors for cut­ting pipes;
  • adjustable or gas key;
  • cal­i­bra­tor (if pipes are made of met­al-plas­tic);
  • tape mea­sure and mark­er;
  • set of wrench­es;
  • appa­ra­tus for weld­ing pipes (if you have a plas­tic line);
  • grinder and thread­ing machine (for met­al plumb­ing).

Choos­ing an instal­la­tion loca­tion device, keep in mind that for prop­er oper­a­tion, the water meter must be pro­tect­ed from adverse fac­tors:

  • mechan­i­cal or chem­i­cal dam­age;
  • tem­per­a­ture fluc­tu­a­tions.

Month­ly to you take water meter read­ingsperi­od­i­cal­ly hand them over for inspec­tion to the appro­pri­ate ser­vices and change fil­ters for clean­ing, there­fore free access is also required.

installation in hard-to-reach places

Between the main water sup­ply ris­er and the meter there should be no out­lets or plumb­ing fix­tures in which the water flow will not be record­ed by a water meter.

Assembly scheme of elements

Water meter instal­la­tion begins with the assem­bly of the struc­ture, which includes:



  • water meter;
  • coarse fil­ter;
  • check valve;
  • union nuts (Amer­i­can);
  • ball valve.

Below scheme will help you do every­thing quick­ly and cor­rect­ly.

assembly diagram of elements

  • Before Assem­bly study the instal­la­tion rules, instruc­tions and data sheet.
  • Lay out the mate­ri­als in a row (see dia­gram). Notice the arrows.
  • Make a pre­lim­i­nary “dry” assem­bly of the mech­a­nism. It is nec­es­sary in order to deter­mine the num­ber of turns for thread­ed con­nec­tions (the water meter sump should look down), and will also help deter­mine the length of the pipe sec­tion that will need to be cut.
  • Tak­ing every­thing apart again con­nect using spac­ers for union nuts and fum-tape (san­i­tary linen or tan­git) for oth­er thread­ed con­nec­tions.

The Amer­i­can comes with the device, but seal­ing gas­kets may have to be bought sep­a­rate­ly, since hot water requires paronite gas­kets, and rub­ber gas­kets for cold water.

  • In the assem­bled struc­ture, all ele­ments must be locat­ed as indi­cat­ed in the dia­gram.
  • Fil­ter before counter will need to be cleaned peri­od­i­cal­ly, so if access to it is dif­fi­cult — turn it a lit­tle to the side.

Insertion into the highway

The mech­a­nism is assem­bled and Now you can start tap­ping into the water main.

For this it is nec­es­sary using a tape mea­sure to make accu­rate mea­sure­ments of the assem­bled counter unit — it is such a piece of pipe that we need to remove. Be sure to turn off the water sup­ply!

We use special fittings for metal pipes

  • If you have a met­al sys­tem, then the best option would be to replace part of the plumb­ing with plas­tic ele­ments, using spe­cial fit­tings for the tran­si­tion. Oth­er­wise, you will have to cut threads on the pipes.

fix fittings on metal-plastic pipes

  • In the pres­ence of a plas­tic or met­al-plas­tic water sup­ply it is nec­es­sary, with the help of scis­sors, to cut off a piece of pipe. Fit­tings for met­al-plas­tic pipes con­nect­ed to a pre-cleaned and cal­i­brat­ed pipe.

soldering of polypropylene pipes and fittings

  • If polypropy­lene pipes are installedthe cou­plings will need to be weld­ed into the struc­ture using a weld­ing machine.

connecting the device to the water supply

  • We con­nect the device block with fixed fit­tings.

After instal­la­tion, it is nec­es­sary to check the oper­a­tion of the sys­tem.

  • Open the tap on the ris­er and turn on the water.
  • Slow­ly turn the stop­cock on the meter block to the stop.
  • If there are no leaks and the device is func­tion­ing nor­mal­ly, you have com­plet­ed the first part of the task.

Commissioning

The meter is installed and work­ing prop­er­ly, but until you call the inspec­tor, you will con­tin­ue to pay at the old rates.

Need to con­tact ser­viceswho con­trol and oper­ate the water main.pay new rates

If you live in a hous­ing coop­er­a­tive or con­do­mini­um, con­tact the admin­is­tra­tion. In oth­er cas­es — direct­ly to Vodokanal.

An inspec­tor will vis­it you with­in 3–5 days vodokanal or an autho­rized employ­ee of the hous­ing coop­er­a­tive or hous­ing asso­ci­a­tion. He must draw up an act of com­mis­sion­ing, where the ini­tial read­ings of the meter will be entered.

You will receive a ser­vice con­tract, which must be read care­ful­ly, and all ques­tions you are inter­est­ed in ask­ing before you sign the doc­u­ment. A copy of the con­tract and the act, as well as the orig­i­nal pass­port for the device, remains with you.

filling

water meter sealing

The leg­is­la­tion of the EU stip­u­lates that seal­ing of meters should be free of charge dur­ing the ini­tial instal­la­tion of devicesas well as after a sched­uled inspec­tion or repair.

Keep this in mind if the inspec­tor sud­den­ly wants to mis­lead you. He is oblig­ed to seal the assem­bly free of charge and doc­u­ment the process.

If dur­ing the use of the seal is dam­aged due to your fault — imme­di­ate­ly report it. Con­tact details must be spec­i­fied in the con­tract.

For re-seal­ing you will have to pay from 500 to 20 dol­lars (depend­ing on the con­tract), but this amount will be much low­er than what you will be required to if dam­age to the seal is found by the inspec­tor dur­ing a sched­uled inspec­tion.

Verification

Ver­i­fi­ca­tion of water meters is car­ried out by metro­log­i­cal orga­ni­za­tions of the state and pri­vate prop­er­ty sys­tems. You need to car­ry out peri­od­ic ver­i­fi­ca­tion your­self, involv­ing spe­cial­ists for this.

Planned pro­duced 6 years after the instal­la­tion of a water meter for cold water and 4 years for hot water.

unsched­uled ver­i­fi­ca­tion is per­formed only if there is a sus­pi­cion of an incor­rect dis­play of water con­sump­tion or a break­down.

Ver­i­fi­ca­tions are car­ried out in two ways:

  • with dis­man­tling of the device and sub­se­quent deliv­ery to the inspec­tion orga­ni­za­tion
  • with the call of a spe­cial­ist — at home, i.e. with­out removal

In the first case – A spe­cial per­mit is required to remove the device. The inspec­tor must come and record the read­ings of the device, give you the rel­e­vant doc­u­ments. Take the water meter and pick it up your­self. Then the instal­la­tion and again paper­work with the call of the con­troller.

If the device fails the test, you will still need to pay for it and take care of buy­ing and installing a new one. The min­i­mum cost for every­thing is 1250 rubles.

In the sec­ond case — ver­i­fi­ca­tion is car­ried out by a ser­vice employ­ee on site using a portable ver­i­fi­ca­tion stand. The cost of the pro­ce­dure is much low­er (500–6 dol­lars).

The down­side is that the qual­i­ty of work is checked by the device, which, using high-pre­ci­sion scales, weighs the water pass­ing through the water meter. Inter­nal dam­age and wear of parts can­not be detect­ed in this way.

For infor­ma­tion on how ver­i­fi­ca­tion is car­ried out at home with­out remov­ing meters, see the video:

In some regions, the ver­i­fi­ca­tion of water meters has been can­celed and there­fore ille­gal. We advise you to clar­i­fy infor­ma­tion on your region in the Man­age­ment Com­pa­ny or Vodokanal.

How much does it cost to install by a specialist

Aver­age instal­la­tion cost one water meter with reg­is­tra­tion and seal­ing is 28$. Con­tact only licensed and expe­ri­enced pro­fes­sion­als.

As you can see, no fun­da­men­tal knowl­edge is required to install a water meter. Per­haps much more ener­gy will take away from you com­mu­ni­ca­tion with rep­re­sen­ta­tives of reg­u­la­to­ry author­i­ties.

Be alert — don’t let your­self be fooled. Bold­ly and deci­sive­ly stand up for your rights!
