How to eliminate the smell of sewage in the bathroom, causes


bad smell in the bathroom

Mankind has man­aged to make a com­fort­able place out of the bath­room. But even mod­ern bath­rooms and toi­lets can have an unpleas­ant odor that even the best air fresh­en­ers can’t deal with.

Yes, and you should not do this, because the stench is not only unpleas­ant, but also harm­ful. There­fore, it is nec­es­sary to imme­di­ate­ly begin to search for the cause.

Why does the bathroom smell like sewage?

There are sev­er­al rea­sons for the spread of sew­er amber: from a banal clog­ging of a pipe to a mal­func­tion of ven­ti­la­tion. Let’s dwell on each of them in more detail.

Incorrect installation of the system

If the “aro­ma” of the sew­er began to spread in your new or just ren­o­vat­ed hous­ing, then the rea­son is most like­ly the incor­rect instal­la­tion of the sew­er­age net­work.

In this case, vio­la­tions often man­i­fest them­selves in three ways:

wrong drain slope

  1. The most dif­fi­cult case is non-obser­vance of the slope when installing the wiring. Insuf­fi­cient angle of incli­na­tion of the pipeline leads to stag­na­tion of drains. Exces­sive slope is also bad, as in this case the liq­uid will quick­ly evac­u­ate, and larg­er and heav­ier waste will stag­nate and clog the pipe.
  2. Incor­rect instal­la­tion of the water seal leads to the fact that it does not retain water, which should pre­vent the pen­e­tra­tion of gas­es from the sew­er. Errors in the arrange­ment of sew­er ven­ti­la­tion can also lead to snatch­ing of the water seal when flush­ing large por­tions of waste­water.
  3. If when con­nect­ing pipelines joints were not prop­er­ly sealedthen these places are the source of stench.

Hidden violation of the integrity of the pipes and the accumulation of condensate

Leaks, imper­cep­ti­ble at first glance, are anoth­er com­mon cause of stench in the bath­room. Such defects are very dif­fi­cult to detect, as they can appear in hard-to-reach places, for exam­ple, on a pipe sec­tion immured in the floor or wall.

In this case, the sit­u­a­tion is aggra­vat­ed if mois­ture seeps into the ceil­ing, form­ing dia­per rash, and destroys the wood­en ele­ments of the sub­floor.

Moist­en­ing of floors can also occur when con­den­sate forms on the pipes. This phe­nom­e­non is pos­si­ble if the pipeline pass­es in places of tem­per­a­ture dif­fer­ences.

As a result, putre­fac­tive bac­te­ria and mold fun­gi active­ly devel­op.

Malfunctions in the water seal

water sealMal­func­tions in the oper­a­tion of a water seal can occur not only as a result of incor­rect instal­la­tion, but also dur­ing its oper­a­tion.. Prob­lems appear for sev­er­al rea­sons:

  • as a result of clog­ging or freez­ingb;
  • due to stretch­ing of the cor­ru­gat­ed pipe with time;
  • due to clogged drain pipelead­ing to a vio­la­tion of sew­er ven­ti­la­tion and snatch­ing of a water plug when drain­ing water into a ris­er;

In the lat­ter case, when a large vol­ume of liq­uid enters, for exam­ple, when flush­ing from a toi­let bowl or when a wash­ing machine is run­ning, you can hear a char­ac­ter­is­tic squelch­ing sound com­ing from small siphons.

Loss of water from the siphon can occur if the plumb­ing is not oper­at­ed for a long time. The liq­uid will just evap­o­rate.

Insufficient ventilation

In addi­tion to the sew­er ven­ti­la­tion ris­er, the bath­room needs air ven­ti­la­tion, which can be forced and nat­ur­al.. For a bath, air exchange is espe­cial­ly impor­tant, as this is a humid room.

The accu­mu­lat­ed liq­uid leads to the devel­op­ment of mold and putre­fac­tive microbes and the spread of an unpleas­ant odor.

Clogged pipes

sewer blockage

Sew­er pipes are high­waysalong which con­t­a­m­i­nat­ed water moves with hair, fat, ani­mal hair, some­times thick paper and sand that have fall­en into it.

Large waste can lead to the for­ma­tion of an obstruc­tion. Also, dur­ing oper­a­tion, the walls of the pipes become over­grown with plaque, which caus­es a nar­row­ing of the lumen.

Block­age is not only a source of unpleas­ant odor in itself, but also dis­rupts the oper­a­tion of the entire sew­er sys­tem, includ­ing water seals. And it is in the siphons that the accu­mu­la­tion of con­t­a­m­i­nants occurs most often.

Smell from washing machine

Some­times the smell comes from the wash­ing machine, which can devel­op mold.. This is espe­cial­ly com­mon if the tech­nique is used fre­quent­ly, and for wash­ing, a mode with a tem­per­a­ture of no high­er than 30 degrees is almost always cho­sen.

Some­times the drain hose is clogged or the oper­a­tion of the sump pump is dis­rupt­ed.

Thus, many caus­es of bad smell in the bath­room are relat­ed to each oth­er. In many cas­es, you can fix them your­self.

How to deal with the smell in the bathroom?

After deter­min­ing the cause of the stench, you can begin to take mea­sures to elim­i­nate it. If we are talk­ing about an apart­ment build­ing and prob­lems, such as block­age, are in the gen­er­al house drainage sys­tem, then it is nec­es­sary to involve employ­ees from the man­ag­ing orga­ni­za­tion.

Pipes for water supplyIt is very impor­tant to prop­er­ly install and install pipes for the pipeline in a pri­vate house, because in most cas­es it is the wrong arrange­ment of the sew­er that caus­es an unpleas­ant smell in the bath­room.

In case of local­iza­tion of mal­func­tions inside an apart­ment or in a pri­vate house, they must be removed inde­pen­dent­ly or with the help of hired spe­cial­ists.


  1. If it is found that the sew­er was installed with vio­la­tions, then it will be nec­es­sary to com­plete­ly redo it or make changes to some sec­tions. For this, it is bet­ter to call an expe­ri­enced plumber.
  2. Leaks often occur at joints. Pipelines must be dis­con­nect­ed and recon­nect­ed and sealed. If the leak occurs due to a vio­la­tion of the integri­ty of the pipe, then it is nec­es­sary to seal the crack and sub­se­quent­ly replace the dam­aged area.
  3. Accu­mu­la­tion of con­den­sate on the pipe due to tem­per­a­ture dif­fer­ences pre­vent­ed by insu­la­tion.
  4. The work of the siphon can be restored in var­i­ous ways., the choice of which depends on the cause. This can be clear­ing the block­age, elim­i­nat­ing the sag­ging of the cor­ru­ga­tion with the help of clamps, pour­ing hot water into the pipe to defrost ice, restor­ing the paten­cy of the fan ven­ti­la­tion pipe.
  5. Air ven­ti­la­tion is cleaned by a spe­cial­ist. If the move is free, but the removal of mois­ture is not enough, then you can install a grill with a fan that removes air forcibly.
  6. When the stench comes from the wash­ing machine, it is nec­es­sary to start an emp­ty wash in boil­ing mode with deter­gent. After that, care­ful­ly wipe the drum and cuff. Anoth­er mea­sure is to clean the drain pump and hose.
  7. Block­ages in sew­er pipes elim­i­nat­ed with the help of spe­cial tools, cables. There are even elec­tric pipe clean­ers used by spe­cial­ists.

The main caus­es of stench in the bath­room are block­ages and leaks in pipes, as well as prob­lems with sew­er ven­ti­la­tion and siphon.

Trou­bleshoot­ing can be done inde­pen­dent­ly or with the involve­ment of spe­cial­ists. But much more effec­tive pre­ven­tionwhich includes sev­er­al activ­i­ties.

  1. When installing sew­er­age, it is nec­es­sary to avoid a large num­ber of joints and turns and place them in acces­si­ble places.
  2. Impor­tant use pipelines and fit­tings of the cor­rect diam­e­terhigh qual­i­ty and observe the slope when installing.
  3. Build­ing waste must not be thrown into the sew­errags and oth­er waste that will cause pol­lu­tion.
  4. Costs clean the siphon reg­u­lar­ly and sew­er pipes.
  5. After kitchen sinks and dish­wash­ers rec­om­mend install grease traps.
  6. If the pipeline pass­es in places of tem­per­a­ture dif­fer­ence, then need to be insu­lat­ed his.
  7. Entrust the instal­la­tion of the entire sew­er net­work to pro­fes­sion­als.
  8. If you have to leave your home for a long time, it is rec­om­mend­ed pour a lit­tle veg­etable oil into the siphonswhich will pre­vent the liq­uid from evap­o­rat­ing.

Com­pli­ance with these sim­ple rules will help pre­vent the occur­rence of odor.
