Blocked Drain? Try These, In This Order

Try this first — the self-help checklist

Work down the list and stop the moment something works. Every step assumes you have stopped adding water to the problem.

• Clear the visible. Lift out the plug or trap cover and remove anything you can see — hair and soap at a bathroom plughole solve a surprising share of cases.
• Plunge properly. Block the overflow with a wet cloth, get a full seal over the plughole, and use firm, rhythmic strokes — the seal matters more than the force.
• Empty the trap. Under a sink, a bowl beneath the U-bend and a careful unscrew often produces the blockage in your hand. Wear gloves; have a towel down.
• Hot water, not boiling. A kettle of hot (not boiling) water with washing-up liquid can loosen greasy kitchen clogs — boiling water can deform plastic waste pipes and stress older joints.
• Two failed attempts = stop. More force from here tends to compact the blockage or crack a fitting. Time to hand it over.

What never goes down a drain — pin this up

Nearly every kitchen blockage a plumber clears started as a habit. The prevention checklist is shorter than the cure:

• Fat, oil and grease — pour into a jar or tin, bin it once set; hot fat is liquid right up until it reaches your cold pipe
• Coffee grounds and tea leaves — they settle and pack like wet sand
• Rice, pasta and flour — all swell or paste up with water
• Wipes of every kind, including the packet that says flushable
• Cotton wool, buds, dental floss and hair — bin, not bowl
• Plaster, grout or paint washings — they set underwater, exactly where you least want concrete

One fixture, or the whole house?

This is the fork in the road, and it takes one minute to check. Walk the house and tick what you find:

• Only one plughole slow, everything else fine → local blockage in that fixture's run — usually self-help territory
• Two or more fixtures gurgling or slow at once → something shared is blocked further down
• Lowest drains affected first — downstairs loo, shower tray → classic main-drain pattern
• Water or waste appearing at an outside gully or inspection cover → the blockage is outside the house itself

Whose job is it? Drains inside your boundary serving only your home are generally the owner's responsibility; the public sewer is NI Water's. Shared pipes and older layouts can blur the line — around Banbridge's older mill-era terraces the arrangements sometimes predate the modern maps, so it is worth establishing whose pipe it is before anyone quotes for digging.

Outside gullies, leaves and the once-a-year habit

The outside gully — the grated drain that takes sink, washing machine or rainwater — quietly builds a felt of leaves, silt and grease until one wet week it stops coping. In the newer estates the gullies are young and mostly need a seasonal clear; around older properties, garden soil levels have often crept up over the decades and the gully sits deeper than it should. Once a year, lift the grid, scoop out what has collected, and run a hose through. Two minutes in October saves a courtyard of grey water in January — and if a cleared gully still backs up, that is a rodding job, not a bucket job.
