Introduction: The hazardous nature of blocked drains

A drain blocked can usher in serious health threats to your home in St Peters, Sydney. Over time, clogged pipes and backed up wastewater allow contaminants to build up, leading to foul odours, property damage, and even health hazards.

When drains become completely obstructed, sewage and unclean water can flow back into your sinks, showers, and toilets. This stagnant water provides the perfect breeding ground for bacteria, mould, and pests.

It similarly enables toxic gases such as hydrogen sulphide to find its way inside, emanating that rotten egg smell and jeopardising your family’s health.

Blockages that linger unresolved for an extended period can result in extensive destruction. Tree roots trespassing into age-worn sewerage pipelines represent a common cause for blockages, leading to frequent sewer line damage and resulting in leaks, inundations, and costly repairs.

The takeaway from this blog post is that clogged drains are far more worrisome than mere irritations. Our comprehensive guide will arm readers with preventative information while underscoring how quickly unblocking drainage in your house is vital for health. Swift action curtails the destructive effects blocked drainage on your property can cause, ensuring the well-being of your family.

Health risks posed by blocked drains

Exposure to black mould spores is associated with conditions that can make you ill, such as respiratory issues, skin irritations, and infections. Allowing stagnant water to pool in your home also attracts pests like mosquitos and rats that carry diseases.

Disease transmission

When a drain blockage occurs, sewage backups and leaks can arise, causing concern as waste-borne bacteria can affect your household. When tainted water meets your skin, eyes, or is inadvertently swallowed, microorganisms such as viruses, bacteria, and parasites can invade and begin to wash your insides with infection.

Some of the most common illnesses transmitted by exposure to sewage from a blocked drain include:

  • Gastroenteritis - Characterised by diarrhoea, fever, vomiting, and stomach pain
  • Conjunctivitis - An eye infection causing redness, swelling and itchy discharge
  • Typhoid fever - A sometimes fatal illness with symptoms like high fever, weakness, stomach pain, constipation or diarrhoea

Toxic gas exposure

Hazards associated with blocked drains include sewer gas emissions like hydrogen sulphide, methane, and carbon monoxide, which can invade your St Peters home. Exposure to these noxious sewer fumes, even at diminished intensities, over lengthy periods can trigger health complications, which causes great concern.

Inhaling hydrogen sulphide gas, which smells like rotten eggs, causes nausea, headaches, and dizziness in the short-term. But long-term exposure can lead to loss of appetite, breathing difficulties, and neurological damage.

The methane gas that a blocked drain can cause has side effects that are extremely dangerous due to its flammable and explosive nature. If ignited, it can cause severe burns and property damage. Meanwhile, odourless carbon monoxide displaces oxygen in the blood, resulting in asphyxiation.

If you suspect your blocked drain is emitting dangerous gases, clear everyone out of the home immediately. Contact our gas certified 24/7 emergency plumbing team to inspect your pipes and prevent potential sources that could damage your home before the property can be reoccupied.

Drains can lead to becoming hotspots for pests such as cockroaches, rats, and mosquitoes, hindering the water flow and acting as vectors for diseases. As sewage and dirty water accumulate, it permits these insects and rodents, which could lead to disease, to venture into your home in search of sustenance and hydration.

Once inside, they proliferate swiftly and can spread germs via their droppings and urine. Rats also bite through wires, wood, and even cement, causing severe infrastructure damage.
