Blocked sewer lines pose a risk to health. Apart from the bad smell and the ugly site of a blocked drains spilling dirty water outside, there are health issues relating to exposure to sewer drain gases. Health problems common from raw sewerage exposure can come from bacteria or parasites. Clogged sewer drain is a problem that needs no motivation to act on, and drain cleaning specialists are always ready to jump at short notice.
Sewerage pipe systems transfer waste water that collects from sinks, bathrooms and other home appliances. Domestic appliances such as washing machines, dish washers and ice machines for instance, will collect and end up in sewer pipes.
The drainage pipes collecting waste water from all other areas are smaller than the one that collects from toilet. However, drain pipes within a building connect outside the building into one system. Therefore, the sewer drainage pipes outside are wider in diameter than the ones from inside.
How Sewerage Pipes Run
Drain pipes run at slope to enable movement of raw sewerage. The drainage pipe system is therefore not working under pressure except the natural effect of gravity. This means that the system should be free of objects that prevent flow of water. Sanitary pads, hairs, fatty substances and other forms of unwanted solids are the main culprits for a clogged sewerage pipe.
Ideally, sewer pipes should have an inspection point, to allow for drain plumbers to clean out the sewer clog.
For obvious reasons, a sewer line runs underground. Therefore, sewer drain system is one of the most common forms of underground utilities.
PVC is now the most common material in use for sewerage drain pipes. Pipe diameter usually for domestic outside sewer drainage pipes outside the house is 110mm diameter. For sink, bathroom, washing machines and all interior waste water drainage, a 50mm size PVC pipe is used.
Grease, fatty substances, soaps and food particles are common causes for interior drain blockages.
How to Detect Early Warning Signs of Blocked Sewer Lines
Slow draining of toilets and bathroom should not be ignored. They indicate that a drain block is present. Debris can begin to pile up following this, and eventually a full drain block will occur.
Additionally, if you start smelling funny and foul smells then it is time to consider a drain cleaning exercise.
Another common sound is the unmistaken gurling sound that follow after flushing, or when water from a tub is released.
The last thing to confirm a total blockage of sewerage system is a flooding on the outside of the house. At this point, the drain pipe is fully blocked.
