What’s the most common cause of blocked sinks?
The most common cause of a blocked sink depends on whether it’s a kitchen sink or a bathroom sink.
Kitchen Sink Blockages
In kitchens, blocked sinks are often caused by a build-up of fat, grease and food residue inside the drainpipes.
When cooking oil or grease is hot, it flows easily in liquid form. However, once rinsed down the sink with cold water, it quickly solidifies and sticks to the inside of the pipes. Over time, layers of grease can build up and trap food particles, eventually restricting water flow and causing a blockage.
Dishwashers can also contribute to this problem by washing grease and food residue into the same drainage system.
If your kitchen sink is draining slowly, a kettle of boiling water may sometimes help loosen built-up grease. However, if the blockage keeps returning, the issue may be deeper within the drainage system.
In older homes and established areas such as Geelong and surrounding suburbs, ageing pipes and underground damage can also contribute to recurring blocked drains.
Bathroom Sink Blockages
In bathrooms, the most common cause of blocked sinks is usually hair combined with soap residue and toothpaste build-up.
Many homeowners don’t realise that bathroom sinks, showers and baths are often connected to the same drainage line. Hair washed down the shower can combine with soap scum and debris, forming large clogs within the pipes over time.
While hot water or supermarket drain cleaners may occasionally provide temporary relief, they often don’t remove the root cause of the blockage.
When the Problem Is Deeper Underground
Recurring blocked sinks can sometimes indicate a more serious issue within the drainage system, including:
-
Tree root intrusion
-
Cracked or damaged pipes
-
Collapsed drains
- Build-up deep within underground pipes
At The Drain Man, we use advanced CCTV drain cameras to inspect your drains and identify the exact cause of the blockage. Once identified, we use professional high-pressure water jetting and specialised drain clearing equipment to restore proper flow.
If the drain is damaged, we can also provide no-dig drain relining, allowing pipes to be repaired without excavating your garden, driveway or landscaping.
