There is a particular kind of frustration reserved for a drain that has been cleared three times. Each time it runs freely for a few weeks, and each time it comes back, which is a strong signal that nobody has yet found out why it blocks.
Tami Plumbing carries out drain unblocking in Nottingham, and the working principle is to deal with the cause rather than push the blockage further down the pipe. Here is what a recurring blockage is usually telling you.
Clearing is not the same as fixing
A blockage can be cleared in several ways, and some of them simply move the problem. Rodding a soft blockage can push it along to a point where the pipe widens, where it will settle and rebuild. Chemical products can eat a hole through a mass of grease without removing the rest of it.
Either approach produces a drain that runs freely, which is why the fix feels successful and then fails again on roughly the same timetable. The material was never removed and the reason it accumulated was never addressed.
The first diagnostic questions are where the water is backing up, whether more than one fixture is affected, and whether the problem is inside the property or in the external drainage. Those three answers separate a local fixture problem from something further down the line.
If only the kitchen sink is slow, the problem is near the kitchen. If the sink, the bath and the toilet all back up, the problem is downstream of all of them and clearing the sink trap will achieve nothing.
- One slow fixture points at a local trap or waste.
- Several fixtures backing up points downstream of all of them.
- Gurgling elsewhere when you drain a fixture indicates a shared restriction.
- A blockage that returns on a schedule has a cause nobody has removed.
What actually causes each type
Kitchen sinks block with fat and food waste. Fat leaves the pan as a liquid and cools into a solid inside the pipe, gradually narrowing it while catching everything else that passes. That is why kitchen blockages build slowly and then appear to happen suddenly.
Bathroom wastes block with hair and soap, which bind together into a mat that catches on anything protruding inside the pipe. Showers and baths are the usual victims, and the trap is the usual location.
Outside drains block with leaves, silt or root disturbance. Roots are the serious one, because they mean the pipe has a defect they entered through, and clearing them without addressing the pipe guarantees a return.
The right method depends on access, pipe condition and whether the blockage keeps returning. A pipe in poor condition is not a candidate for the most aggressive clearing technique, which is exactly why the assessment matters more than the equipment.
When it is worth putting a camera down
For a first-time blockage in an obvious place, clearing it is a reasonable response. For a third blockage in the same run, guessing has already been tried and has failed twice.
A camera survey answers the question directly: is there a defect, a displaced joint, a root intrusion, a sag holding water, or simply a build-up. Those have different remedies, and no amount of jetting distinguishes between them.
Tami Plumbing uses CCTV cameras and high-pressure jetting to find and fix the problem properly, and the combination matters. Jetting removes what has accumulated; the camera establishes whether something structural caused it to accumulate there.
It is worth paying for the answer once rather than paying repeatedly for the symptom. A recurring blockage that turns out to be a broken pipe will keep returning forever until the pipe is dealt with.
- First blockage in an obvious place: clearing is a fair first response.
- Third blockage in the same run: find out why, rather than clearing again.
- A camera distinguishes a build-up from a defect, sag or root intrusion.
- Roots always mean a defect they entered through.
Habits that keep drains clear
Most kitchen blockages are entirely preventable. Fat, oil and grease should go in the bin once cooled rather than down the sink, however liquid they look at the time. A sink strainer catches the food waste that would otherwise feed the fat already in the pipe.
In the bathroom, a hair catcher over the shower waste removes the single biggest contributor, and cleaning traps occasionally is far easier than clearing a blockage from them.
Only the obvious three things should go down a toilet. Wipes labelled flushable are the most common cause of avoidable blockages, and they do not break down in the way toilet paper does.
Outside, clearing gullies of leaves and silt before autumn does more than any product. A blocked toilet during an emergency may need emergency plumbing, damp patches or smells after a drain issue may need leak detection, and repeated bathroom blockages may connect to bathroom fitting or fixture replacement rather than to the drain itself.

Questions customers ask
Why does my kitchen sink keep blocking?
Almost always fat and food waste. Fat pours as a liquid and sets solid inside the pipe, narrowing it and catching everything else. Clearing it without changing what goes down the sink means it rebuilds on roughly the same timetable.
Are chemical drain cleaners a good idea?
They can open a channel through a blockage without removing it, which is why the problem often returns. They can also damage older pipework and are unpleasant to work around afterwards. Physical removal deals with the material rather than tunnelling through it.
When should I have a drain camera survey?
When the same run blocks repeatedly. A camera distinguishes a simple build-up from a defect, a displaced joint, a sag holding water or root intrusion, and those need different remedies. Paying for the answer once beats paying for the symptom repeatedly.
One slow fixture is local. Several is downstream. A third blockage in the same place is a question that deserves a camera rather than another rod.
