A blocked drain is frustrating enough the first time, but when the same drain keeps blocking, it’s usually a sign that something more is going on beneath the surface.
While a plunger or drain cleaner may provide temporary relief, recurring blocked drains often indicate an underlying issue that needs professional attention. Identifying the cause early can help prevent more extensive plumbing repairs and reduce the risk of damage to your property.
Here’s why your drains may keep blocking and what can be done to fix the problem properly.
What Causes Recurring Blocked Drains?
There are many reasons a drain may continue to block, even after it’s been cleared.
Some of the most common causes include:
- Tree roots entering underground pipes
- Grease and food waste building up in kitchen drains
- Hair and soap residue collecting in bathroom pipes
- Wet wipes, paper towels or sanitary products being flushed
- Damaged or collapsed pipework
- Pipe movement caused by ground settlement
While some blockages are easy to remove, others require specialist equipment to identify the source of the problem.
Signs the Blockage May Be More Serious
Recurring blockages are rarely the only warning sign.
You may also notice:
- Water draining slowly
- Gurgling sounds from sinks or toilets
- Bad smells coming from drains
- Water backing up into showers or floor wastes
- Multiple drains blocking at the same time
These symptoms often suggest the problem is deeper within the drainage system rather than inside a single fixture.
Why DIY Drain Cleaners Often Don’t Work
Many supermarket drain cleaners are designed to dissolve small blockages close to the drain opening. Unfortunately, they won’t remove tree roots, repair damaged pipes or clear large sewer obstructions.
Repeated use of harsh chemical cleaners can also damage some types of pipework over time.
If your drain keeps blocking despite using these products, it’s worth having the system professionally inspected rather than continuing with temporary fixes.
How Our Plumber Finds the Cause
When recurring blockages occur, Our Plumber may recommend a CCTV drain inspection.
A small waterproof camera is fed through the drainage system, allowing our plumbers to inspect the inside of the pipe without unnecessary digging.
This helps identify issues such as:
- Tree root intrusion
- Cracked or collapsed pipes
- Grease build-up
- Pipe misalignment
- Foreign objects lodged in the drain
Once the cause has been identified, we can recommend the most effective long-term solution, whether that’s high-pressure drain cleaning, pipe repairs or replacement of damaged sections.
