Before we move on to how to unclog a drain, let us first understand common drain clogging areas and its warning signs.

Common Drain Clogging Areas

In your home, clogs can occur in different areas for different reasons. Here are the common areas where clogging occurs and their reasons:

01. Toilet Clogs

Toilet clogs are one of the most dreaded blockages and should be avoided at all costs. They are mainly caused by non-dissolvable items flushed into the toilet, such as polythene, wet wipes, sanitary napkins, tampons, and others. These items do not break down over time and may also swell, causing severe drain blockages.

It is important to address this issue immediately, as any delay can eventually lead to wastewater backflow.

02. Kitchen Sink Clogs

Kitchen sinks get clogged every now and then. The main reasons behind this are grease, oil, stringy vegetables, fibrous materials, and starchy peels and grains. These substances overwork the kitchen sink and can block the drain. Over time, they accumulate, slowing down drainage and eventually causing wastewater to back up and overflow.

03. Shower Drain Clogs

Shower drain clogs are more frequent than you think, mostly because of soap scum, dirt, hair, sand, body oils and grease, and shampoo and conditioner residue. Clogged shower drains can cause a messy, foul-smelling bathroom.

Signs of Clogged Drain You Should Not Ignore

Clogged drains always give warning signs. It is in your best interest to acknowledge these signs and work on unclogging the drain as early as possible. Below are the five common signs of a clogged drain:

01. Bad Odour

Is there a foul smell coming from the drains? If yes, then there is a problem with your pipes, most likely a clog. When the drains are clogged, the waste flushed via pipes accumulates and rots with time. This results in a foul sewage smell coming from the drains. 

02. Toilet not Flushing

When you notice that your toilet is no longer flushing properly, or has backflow, it is a warning sign of a clogged sewer pipe. A blocked toilet is no longer usable and needs immediate fixing.

03. Plants and Flies Around Drainage Lines

Clogged drains and pipes often lead to leakages. Puddles form due to prolonged drain pipe leakages, and these puddles are signs of drain clogs. If left unattended and there are shrubs nearby, their roots may start growing and intrude into the pipes. Therefore, if you see shrubs or roots around your drain pipes, there is a chance that the roots have penetrated the pipes, causing the drains to clog.

04. Slow Draining

Is the water taking too long to drain from your toilet, sink, or tub? If yes, then your drains may be clogged. To identify the source of the clog, check whether the kitchen is the only area facing the issue. If so, the clog might be originating from the sink pipes.

However, if the toilet also experiences the same problem, the clog may be much deeper, possibly in the sewer pipe.

05. Gurgling Drains

If the toilets have clogs, you may hear bubbling or gurgling sounds when flushing. These sounds occur when air gets trapped due to blockages in the pipes. As water tries to pass through restricted spaces, it creates gurgling noises, an obvious sign of a clogged drain.
