Do-it-yourself ways to repair heating risers


To begin with, let’s define the con­cept of a heat­ing sys­tem ris­er. The ris­er of the heat­ing sys­tem is ver­ti­cal pipes for sup­ply­ing and dis­charg­ing coolant to the heat­ing devices of the premis­es of a mul­ti-storey build­ing, locat­ed one above the oth­er. Usu­al­ly these are two pipes, but there may be one.

In apart­ment build­ings, heat­ing pipes are usu­al­ly made of met­al or cast iron and are there­fore sus­cep­ti­ble to cor­ro­sion. There are also plas­tic pipes that can also leak. Of course, in the event of a leak, you need to call the mas­ter or repair the entire pipe, but some mea­sures can be tak­en inde­pen­dent­ly.

The first thing to do if a leak comes from a pipe in an apart­ment is to place a con­tain­er under the pipe so that water does not go to the neigh­bors, and wrap the dam­aged area with any rag. Next, we call the emer­gency ser­vice, it is nec­es­sary to block the ris­er.

If the mas­ter has to wait a long time (hol­i­days or week­ends) or there is an oppor­tu­ni­ty and desire to car­ry out minor repairs on their own, the fol­low­ing are tips for fix­ing a leak in a cop­per, plas­tic, met­al or cast-iron heat­ing pipe with your own hands.

Let us con­sid­er in more detail the caus­es of mal­func­tions of heat­ing ris­ers.

Causes of failure and the appearance of leaks, breakage of pipes in heating risers

  • So, the most obvi­ous rea­son is dilap­i­dat­ed, old pipes.
  • Incor­rect instal­la­tion of pipes, their incor­rect repair and main­te­nance:
    • leak in a thread­ed con­nec­tion — poor seal­ing of the con­nec­tion, stripped thread, cracks in the con­nect­ing fit­ting;
    • leak­age in the flange con­nec­tion — loose bolts, faulty gas­kets and dis­tor­tions in the flanges;
    • leak­age in weld­ed joints — poor-qual­i­ty weld­ing work.
  • Mar­riage in the oper­a­tion of equip­ment and pipes.
  • When installing plas­tic pipes that are designed for cold water sup­ply, they are deformed for hot water sup­ply.
  • Fit­ting fail­ure.
  • Water ham­mer and fis­tu­la in the pipe, which occurs due to a sharp increase in pres­sure.
  • Out­side the heat­ing sea­son, a pipe break may be due to improp­er hydraulic test­ing.

What to do when a small leak appears and how to fix it with your own hands (clamp, sealant). Repair of met­al, plas­tic, cast iron and cop­per heat­ing ris­ers

If you need to make minor repairs to a met­al pipe in its straight sec­tion or in a weld, you can use epoxy (emer­gency) glue and fiber­glass. Before repair, be sure to clean the dam­aged area of ​​old paint, clean and degrease the pipe. Apply glue and, if nec­es­sary, addi­tion­al­ly strength­en with a met­al clamp. They can be pur­chased in dif­fer­ent sizes on the mar­ket or in build­ing mate­ri­als or plumb­ing stores. A clamp is a rub­ber­ized pad with twin trac­tion, con­sist­ing of a pair of screws, which, in prin­ci­ple, can be made by hand. You will need a strip of thick met­al, a rub­ber pad, wash­ers, nuts and bolts.

Do-it-your­self clamp


Or we wrap the area with a piece of rub­ber and fix it with wire.

You can use sealant. Then we repeat the pre­vi­ous steps (clean, degrease) and apply the sealant clock­wise.

If a leak has formed at the attach­ment points of the ele­ments of the heat­ing sys­tem, you just need to tight­en the fit­ting with a spe­cial key.

Leak­age at joints

Did­n’t help, drip­ping? The rea­son may be the wear of the tow. In this case, it is nec­es­sary to press the fit­ting halfway, remove the old tow, clean the threads and wind a new one. How­ev­er, be care­ful! The pres­sure in the pipes can cause a rup­ture of the junc­tion and a flood.

Still flow­ing? The part thread may be dam­aged. In this case, call a spe­cial­ist, and before he arrives, wrap the leak site (prefer­ably with a piece of rub­ber).

You can wrap the area with water with a ban­dage, gen­er­ous­ly sprin­kling each lay­er with ordi­nary table salt, which clogs all the cracks.

Anoth­er option to close the leak (if the area is small) is to wrap the prob­lem area with a cloth soaked in glue.

To pre­vent the for­ma­tion of leaks in the places of the thread­ed con­nec­tion, it is nec­es­sary to cov­er it with sev­er­al lay­ers of paint.

Repair of a cop­per heat­ing pipe may be nec­es­sary when the met­al is delam­i­nat­ed. The solu­tion is high tem­per­a­ture braz­ing using hard sol­der. In the event of minor dam­age at the bends, low-tem­per­a­ture weld­ing with soft sol­der is used.

Before repair, it is impor­tant to pre-clean the area from dirt and degrease it.


It may be nec­es­sary to repair the fit­ting that con­nects the 2 pipe sec­tions. In this case, it may be suf­fi­cient to replace the nut or gas­ket.

When repair­ing plas­tic heat­ing pipes, the dam­aged ele­ment is replaced with a new one.

If it is not pos­si­ble to replace it, you can wrap a spe­cial rein­forc­ing plas­tic patch around the dam­age and melt it with a weld­ing machine.

So, sum­ma­riz­ing the above, we indi­cate what actions are includ­ed in the repair of the heat­ing sys­tem:

  • elim­i­nate leaks in appli­ances, fit­tings and pipelines,
  • replace a sep­a­rate sec­tion of the heater, tap,
  • insu­late var­i­ous devices and pipes that are in cool­ing or open places,
  • elim­i­nate reverse slopes on pipelines,
  • to install addi­tion­al fas­ten­ers,
  • trou­bleshoot the boil­er
  • replace gauges,
  • clean and rinse ele­va­tors, expan­sion tanks, con­trol and shut-off valves,
  • flush the air col­lec­tor sys­tem and adjust them.

What to do if the radiator section (plate radiator) is damaged

Before per­form­ing this type of work, the first step is to turn off the heat­ing sys­tem. Next, you need to reset the ris­er sys­tem and dis­con­nect the radi­a­tor.

Atten­tion! Before you remove the radi­a­tor, sub­sti­tute some kind of con­tain­er under it, as there will still be water in the ris­er.

We dis­con­nect the dam­aged area with a spe­cial radi­a­tor key and attach a new nip­ple.

We con­nect the heat­ing sys­tem and start the ris­ers.

If the plate radi­a­tor is dam­aged, it is nec­es­sary, in the same way as in the pre­vi­ous case, to turn off the heat­ing and reset the ris­er sys­tem. Next, we clean and degrease the leak, apply a spe­cial mix­ture of cold weld­ing to the area (which is an adhe­sive with a high degree of plas­tic­i­ty made on the basis of epoxy resin), wait for it to hard­en and turn on the heat­ing.

What to do, and who is to blame, if neighbors are flooded from a burst of a heating pipe

Con­sid­er the legal side of the issue of flood­ing, which can occur as a result of leak­ing heat­ing pipes.

So, there is Decree of the Gov­ern­ment of the EU No. 491 of August 13, 2006, which deter­mined that the com­mon house prop­er­ty includes a heat­ing sys­tem along with ris­ers, radi­a­tors, con­trol and shut­off valves, com­mon house heat meters and oth­er equip­ment on these net­works.

The man­age­ment com­pa­ny ser­vic­ing the house must check the equip­ment 2 times a year and, at its own expense, trou­bleshoot, change dam­aged radi­a­tors, pipes, etc. How­ev­er, if access to the apart­ment was not pro­vid­ed to inspect the con­di­tion of pipes and equip­ment, the own­er of the home will be to blame for all fur­ther con­se­quences.

Fur­ther. If the own­er inde­pen­dent­ly decid­ed to replace pipes, radi­a­tors, etc. with­out agree­ment with the man­age­ment com­pa­ny — the respon­si­bil­i­ty for the con­se­quences pass­es to the own­er.

It is rec­om­mend­ed to keep all receipts and con­clude con­tracts when car­ry­ing out any work with the heat­ing sys­tem in order to sub­se­quent­ly resolve the issue in court.

Atten­tion! There is a deci­sion of the Supreme Court of the EU of Sep­tem­ber 22, 2009 (No. GKPI09-725), which excludes radi­a­tors with dis­con­nect­ing devices in apart­ments from the com­mon prop­er­ty of the house.


There­fore, this type of ques­tions is always con­tro­ver­sial, and start­ing with the leg­isla­tive acts them­selves.

Doc­u­ments required to file a claim with the court:

  • act of inspec­tion of a flood­ed apart­ment,
  • expert assess­ment of the dam­age caused,
  • pho­to and video mate­ri­als with the con­se­quences of the acci­dent.

And, of course, take con­tracts, checks, etc. with you. (if any) asso­ci­at­ed with the appli­ca­tion.

If the man­age­ment com­pa­ny is to blame, then it is oblig­ed to com­pen­sate the dam­age to the own­er of the “emer­gency” premis­es and the own­er of the affect­ed premis­es with­in 30 days.

If the own­er is to blame, then the best way out is to draw up a peace agree­ment and pre-tri­al com­pen­sa­tion for dam­ages. This will save time and nerves for both par­ties.

And final­ly, the most impor­tant advice: pre­ven­tion, con­trol and time­ly repair will save you from future prob­lems with heat­ing sys­tems.

Repair of heating pipes in an apartment and a private house: features

As men­tioned above, rou­tine inspec­tion (at least 2 times a year) and repairs in mul­ti-apart­ment res­i­den­tial build­ings are car­ried out by the man­age­ment com­pa­ny.

Every­one knows who should take care of every­thing in a pri­vate house — this is the own­er, to whom advice is giv­en in this chap­ter.

Advice. Do all the work, if pos­si­ble, in the warm sea­son. So that dur­ing the heat­ing sea­son you do not have to do with­out hot water and heat­ing.

It is use­ful to know that the heat­ing sys­tem con­sists of three ele­ments:

  • boil­er,
  • radi­a­tors,
  • pipes.

Addi­tion­al ele­ments may be present: floor heat­ing pipes, cir­cu­la­tion pump, etc.

The gas boil­er can only be replaced by agree­ment with the gas ser­vice. She will also do the right thing.

An elec­tric heat­ing boil­er can be repaired in case of the fol­low­ing faults:

  • decrease in heat­ing of the coolant,
  • fail­ure of the con­trol unit,
  • flow,
  • pow­er surges in the net­work, poor-qual­i­ty water that caus­es scale and salt deposits on the heat exchang­er, etc. exter­nal fac­tors.

First of all, we check the indi­ca­tors of the pow­er sup­ply, the pres­sure in the sys­tem and the lev­el of water con­sump­tion. We check the cor­rect con­nec­tion of the elec­tri­cal wiring.

Mal­func­tions can also occur in the soft­ware adjust­ments of the boil­er. In this case, you need to com­plete­ly turn off and turn on the boil­er again and per­form a series of actions accord­ing to the instruc­tions received when pur­chas­ing the boil­er.

Reg­u­lar clean­ing of heat exchang­ers from scale will help to avoid more seri­ous break­downs in the future.

Scale in the heat exchang­er before and after clean­ing

With the repair of the heat­ing sys­tem, every­thing is clear. How is a major over­haul car­ried out?

Over­haul of the heat­ing sys­tem includes:

  • replace­ment of the heat­ing cir­cuit (pipes, radi­a­tors, under­floor heat­ing / base­board, etc.),
  • par­tial replace­ment of pipes,
  • instal­la­tion of under­floor heat­ing sys­tem,
  • replace­ment of boil­ers, fur­naces, heat pumps, heat accu­mu­la­tors, etc.
  • com­plete replace­ment of the heat­ing sys­tem.

Of course, major repairs do not need to be car­ried out before each heat­ing sea­son. It is nec­es­sary in the case when repairs are impos­si­ble or unprof­itable, or, for exam­ple, when repair­ing a house.

So, the arti­cle shows how many ways there are to repair heat­ing pipes, both in an apart­ment and in a pri­vate house, but it is also quite clear that there is noth­ing bet­ter than pre­ven­tion.
