Unblock Drain Yourself Exmouth | When to DIY, When to Stop

Most drain call-outs I attend could not have been sorted by the homeowner. A fair number of them could. Telling you which is which costs me work, but it's the honest answer, so here it is.

The jobs you can sort yourself

Let's be clear about what 'drain problem' usually means at a domestic level in Exmouth. Nine times out of ten, it's one of three things: a slow-draining sink, a blocked shower, or a toilet that won't clear on the first flush. All three have a decent chance of being sorted without anyone coming round.

Slow kitchen sink. Fat, soap, and food particles build up just below the plug hole and in the P-trap (that curved pipe under the sink). Before you call anyone, do this:

• Pour a full kettle of just-boiled water down the drain slowly. Wait two minutes.
• If still slow, unscrew the P-trap with a towel underneath, clean it out, refit.
• Still slow? A cup of bicarbonate of soda followed by white vinegar and a ten-minute wait, then flush with hot water.

That sequence clears a good proportion of kitchen sinks. It won't work if the blockage is further down the line, but it costs you nothing to find out.

Blocked shower tray or bath. Hair. It's almost always hair, caught on the drain cover or just below it. Pull the cover off. You'll see it. Pull it out with your fingers or a bent wire. Grim, but fast. A drain cover with smaller apertures (under £5 at any hardware shop) prevents the next one.

Toilet slow to clear. A plunger, used properly, works more often than people think. You need a flange plunger, not the flat cup type. Place it firmly over the outlet, push down slowly to seat it, then pump with purpose. Ten to fifteen strokes. If the toilet clears and flushes cleanly twice, you're done. If it clears but blocks again within a day, something else is going on.

The moment to stop and call

There's a line between a blockage you've fixed and a blockage you've pushed further down the pipe. Cross it, and you've made my job harder and the bill slightly larger.

Stop the DIY and call a drain engineer when:

• Multiple fixtures are affected at once. Sink slow, toilet gurgling, bath backing up. That's not a localised blockage. That's the shared drain beneath your floor, and no amount of plunging from above will shift it.
• The water backs up from a different fixture. You flush the toilet and water appears in the shower tray. The blockage is downstream of both. You can't reach it from the house.
• You've already used a chemical drain cleaner and nothing moved. Caustic cleaners that fail leave a residue that makes jetting more unpleasant and can damage older clay pipes if left sitting. Don't add more on top. Call.
• There's a bad smell coming from outside, or from a manhole. That's not a sink blockage. That's a drain issue in the ground, possibly involving your shared sewer. Don't lift the manhole lid and start prodding.
• The problem keeps coming back every few weeks. A recurring blockage isn't bad luck. Something structural is going on, a partial collapse, a root intrusion, a build-up on a joint. Only a CCTV drain survey tells you which.

The chemical drain cleaner trap

I want to spend a moment on this because I see the aftermath regularly, particularly in older properties on streets like Rolle Road, Cranbrook Road, and the Victorian terraces around Phear Park.

The big-brand chemical unblockers, the ones in the orange or blue bottles, work on one type of blockage: soft organic matter near the surface. For that, they're fine. But homeowners often pour them into a drain that won't move at all, leave them overnight, and nothing happens, because the blockage is a compacted solid mass or tree root fibre that caustic soda cannot touch.

The problem is what happens next. The liquid sits in your pipe. If it's a clay pipe with any cracking, you're etching the surface. If you then call a professional who uses high-pressure water jetting, the chemical mixes with the water and becomes a splashback hazard that engineers have to manage carefully. You haven't helped. You've added a complication.

One chemical product that is genuinely useful is an enzyme-based drain maintainer, something like Bactisept or a similar biological product. Poured monthly into a kitchen sink, it digests grease before it accumulates. That's prevention, not cure, and it actually works over time.

The landlord calculation

If you're renting out a property in Brixington, Withycombe Raleigh, or one of the estates out towards Hulham, there's a specific calculation worth making. If a tenant reports a slow drain and you're tempted to send a maintenance person round with a bottle of unblocker, consider the downside risk. If that 'fix' fails over a weekend and the tenant has sewage backing into a kitchen or bathroom, you're now dealing with an emergency call-out, a complaint, potential damage to flooring, and a very unhappy tenant. A planned drain jetting visit is often cheaper than one emergency call-out. That's not a reason to over-spend on maintenance contracts you don't need, but it's worth factoring in.

The fair caveat

I'm not going to pretend that every blocked drain needs a professional. A kitchen sink that clears after a kettle of boiling water and five minutes with the P-trap doesn't need high-pressure jetting. Anyone who tells you otherwise is wasting your money. The whole point of this post is that some of these jobs are yours to sort, and sorting them yourself is the right call.

But when the simple fixes haven't worked after a genuine attempt, or when the symptoms suggest something beyond a surface blockage, stopping early saves money. Every time I arrive at a job where someone has spent two days trying various fixes, the pipe is in a worse state than it would have been on day one.

Trust what the drains are telling you. One slow sink is probably a sink problem. Three affected fixtures on the same day is a drain problem. The difference matters.
