Unblock Drain Yourself Cirencester | What's Worth Trying

Most drain problems don't need a van on the drive. There. Said it. Half the calls we could take are jobs a homeowner could sort in twenty minutes with stuff already under the sink.

That's not a business model most drainage companies would admit to, but it's true. So here's the honest version: what's worth trying yourself, where the line is, and how to know you've crossed it.

The jobs you can genuinely do yourself

A slow kitchen sink. Nine times out of ten it's a grease and food-debris build-up sitting in the U-bend or just beyond it. Pour boiling water down in two or three stages, not one flood. If that shifts it a bit but not fully, a cup of bicarbonate of soda followed by a cup of white vinegar, then hot water after ten minutes, will often finish the job. Not because it's magic chemistry, it's just mild mechanical fizzing that loosens soft fat deposits.

A sluggish bathroom sink or bath. Hair. Almost always hair, matted around the drain cover or the pop-up plug mechanism. You don't need a product. Get a pair of rubber gloves and pull it out. A cheap plastic drain snake (a few pounds from any hardware shop) reaches the U-bend and grabs what your fingers can't.

A blocked toilet that's your waste and nothing else. A proper plunger, not the small sink one, but a flange plunger with a fold-out rubber cup, creates the pressure needed. Ten firm plunges, wait, flush gently. Repeat. If the blockage is soft material that you put down there, this will usually clear it.

A stinky drain with no actual blockage. Often just a dried-out water seal in a floor gully or rarely-used basin. Pour water down it. If the smell is eggy or sulphurous and comes back fast, that's a different conversation, but a dried trap is a five-second fix.

Where to stop

Here's the thing. The jobs above share one characteristic: the blockage is close, it's soft, and you can reach it. When any of those three stops being true, the DIY odds drop sharply.

Stop and call if:

• Multiple fixtures are draining slowly at the same time. That's not a localised blockage, it's something further down the shared run.
• Water's backing up through a manhole or gully outside. The problem is in the main drain, and jetting, not plunging, is what clears it.
• You've plunged or snaked twice and it's coming back within a day or two. You're clearing the surface of something that isn't going anywhere.
• The drain smells fine on Monday and blocks again by Friday. Recurring blockages in older Cirencester terraces, especially on Watermoor Road, around Chesterton or the older Stratton streets, often signal a partial collapse or root intrusion. A CCTV survey finds it in minutes. Guessing with a plunger doesn't.
• There's any sign of raw sewage surfacing in the garden. Stop. That's a drain failure, not a blockage.

The one thing that catches people out

Chemical drain cleaners. They're sold as the step between the plunger and calling a professional. In practice they're sodium hydroxide in a bottle, and they'll eat through some soft blockages, but they also sit in the pipe if the drain is fully blocked, do nothing, and then you've got a pipe full of caustic liquid that your engineer then has to deal with carefully. If the drain is genuinely blocked and not just slow, don't pour chemicals down it. Either plunge it or call.

A fair caveat

None of this applies to shared drains or anything beyond your private pipework. If you're on one of the newer GL7 estates like Kings Hill or Four Acres, your lateral drain is yours until it hits the public sewer, at which point it's Severn Trent's problem and their number to call. Knowing which is which matters before you start.
