Home › Blocked drains
A sink that will not empty, a toilet rising instead of falling, a smell from the gully outside. Work the clock below — most blockages give themselves away inside twenty minutes.
The one-line answer: stop putting water into the system — no flushing, no washing machine, no taps into the affected run — then work out whether it is one fixture or several. If waste water is backing up into the house, ring 020 4577 2888 now rather than experimenting.
Every litre you add now has nowhere to go but up. Stop the washing machine and dishwasher mid-cycle if they are draining into the affected pipe, keep everyone off the toilet if it is the toilet, and run no more taps into a sink that is already standing full. That single decision is the difference between a blockage and a flood of dirty water across the floor.
Nothing is getting worse now. The blockage is contained — you have time to think.
Walk the house and count what misbehaves. One slow plughole means a local problem — hair, soap or fat in that fixture's trap or branch pipe, annoying but small. Several fixtures at once is different: gurgling from a plughole when the toilet flushes, waste appearing in the bath or shower, the lowest drains in the house struggling first. That pattern points at the main drain. Step outside and lift a look at the gully or inspection chamber if you have one — standing water there settles the question.
Then think about whose drain it is. Runs inside your boundary serving only your home are yours. The public sewer — and usually shared sections between neighbours, common in terraces and the older streets near the town centre — is Scottish Water's responsibility, and sewage surfacing from a public sewer should be reported to them. Do not pay for a repair that is not yours to fund.
For a single blocked sink: bail out the standing water, clear the trap under the sink if you are comfortable unscrewing it (bowl underneath), and try a plunger with the overflow held closed. Hot — not boiling — water helps shift soap and fat in a kitchen waste. For a toilet, a proper flange plunger used slowly and firmly does more than force. What you should not do is pour in round after round of caustic chemicals: they damage older pipework, they sit hazardously in a pipe that stays blocked, and they make the job worse for whoever opens that trap next. One attempt at each safe method is enough.
By now you know what to say: which fixtures are affected, whether the outside gully is standing full, what you have tried, and what — honestly — has been going down that drain. Wipes, cooking fat and sanitary items build most of the blockages a plumber ever meets, and saying so up front changes nothing except how fast the right tool comes off the van. You will get a straight estimate of arrival based on workload and distance, and you can ask for the call-out fee and hourly rate before anyone sets off. If sewage is involved, keep children and pets away from it and wash hands rigorously — it is a health matter as much as a plumbing one.
Once the run is clear, change what goes into it: fat into a jar or the bin, wipes into the bin no matter what the packet claims, a hair catcher in the shower. If the same drain blocks repeatedly, ask about a camera inspection — recurring blockages usually mean a defect in the pipe, not bad luck.
Broadly, drains inside your boundary that serve only your property are your responsibility, while the public sewer — and usually sections shared between neighbouring properties — belongs to Scottish Water. If sewage is surfacing from a public sewer, report it to Scottish Water. A plumber or drainage engineer can help you work out which side of the line your blockage sits on.
Use them sparingly, if at all. Caustic products can damage older pipework, sit dangerously in a still-blocked pipe for whoever works on it next, and must never be mixed with other products. If one dose has not shifted the blockage, stop there — and tell whoever attends exactly what you have already poured down.
A toilet that repeatedly backs up usually points beyond the pan — a partial blockage further down the soil pipe or drain, often built from wipes, sanitary items or cooking fat. Repeated plunging buys time but does not remove the cause, so it is worth having the run properly cleared and inspected rather than fighting it weekly.
Count the fixtures. One slow plughole is a local blockage in that fixture's trap or branch. Several fixtures gurgling or backing up together — especially the lowest ones in the house, and especially when an outside gully or inspection chamber is standing full — points to the main drain. Stop running water into the system and describe exactly that on the phone.
