Running along water supply pipelines inside constructed dwellings are larger pipelines that comprise the drainage, waste, and vent - or DWV network. Drain-waste-vent pipelines slant downwards to facilitate the removal of used tissue paper, waste and dirty water from the home with the power of gravity. Waste matter is flushed from the residence by the drain-waste-vent pipelines via a sanitary sewer pipe network that connects to a central sewage treatment facility. Central sewer lines are susceptible to a selection of plumbing complications like:
Invasive tree roots
Roots love water, and as a result have an inclination to cultivate towards damp origins like subterranean sewer lines. Broadening tree roots fracture and congest sewer lines with hirsute roots entrapping waste substance carried inside. Overtime aggregation of debris and roots plug sewer pipes and stave off effluent from drifting towards the central sewage treatment facility. Thus waste water will reverse courses and backwash into constructed dwellings.
Improper ejection of diapers, hygiene products, wet towels and more in toilets generate intractable clogs in central sewer pipes. Rather than flowing in one direction from house to main, at the point of obstruction wastewater will reverse direction and backflow into houses. Sewer backups are offensive and pollute houses with waste substance.
Drain traps include plugs of water that block unpleasant gas odors from accessing residences. Sewer gas smells invade residences through drains devoid of water seals. Water seal evaporation usually occurs in drains not often used. Dispensing 1 gallon of water through a drain will restore the water plug seal and rectify the trouble of indoor sewer smells.
