Signs Your Sink is Blocked

⚠️

Water draining very slowly

If the sink takes minutes to empty instead of seconds, there's a partial blockage. It'll get worse if you don't sort it. Common in kitchen sinks where grease has built up over time.

⚠️

Water pooling in the sink

If water sits in the sink and won't drain at all, the blockage is complete. It's usually in the trap or just beyond it. Don't use chemical unblockers, they make it worse.

⚠️

Gurgling sound when draining

Gurgling means air is trapped in the waste pipe because water can't flow freely. Often happens in bathroom sinks where hair has caught in the trap and formed a mesh that catches everything else.

⚠️

Bad smell from the plughole

A sewage or rotting smell coming from the plughole usually means there's a build-up of organic matter in the trap or waste pipe. Grease, hair, soap scum, food waste, all decomposing. Needs clearing out properly.

⚠️

Water backing up into another sink

If you run the kitchen sink and water comes up in the bathroom sink (or vice versa), the blockage is in the shared waste pipe. This needs sorting quickly before sewage backs up into the house.

What to Do Before We Arrive

1

Stop using the sink

Don't keep running water into a blocked sink. If it's not draining, you're just filling the trap and waste pipe with more water that has nowhere to go. It'll overflow or back up into another drain.

2

Bail out standing water

If there's water sitting in the sink, bail it out into a bucket so we can work on the trap without water everywhere. Makes the job quicker and cleaner.

3

Clear under the sink

Move bottles, cleaning products, bin bags, whatever's stored under the sink. We'll need access to the trap (the U-bend under the sink) to take it apart. Clear space makes the job faster.

4

Don't use chemicals

Drain unblockers and caustic soda don't work on grease or hair blockages. They just make the water in the trap caustic, which is dangerous for us when we take the trap apart. Leave it for us to clear mechanically.

5

Check other sinks and drains

If multiple sinks or the shower/toilet are draining slowly, the blockage is in a shared waste pipe or the main stack, not just the one sink. Tell us when you call so we know what we're dealing with.

How We Clear Blocked Sinks

1

Remove and clear the trap

We'll put a bucket under the trap, undo the compression nuts, and pull the trap off. Most blockages are in here: hair, grease, food waste, soap scum. We'll clear it out, rinse it, and refit it.

2

Rod the waste pipe if needed

If the trap's clear but the sink's still not draining, the blockage is further down the waste pipe. We'll use a flexible drain snake or rods to push through and break up the blockage.

3

Check the fall and joints

If the waste pipe has insufficient fall (not sloping down enough) or there's a dip where waste collects, the sink will keep blocking. We'll check the pipework and advise if it needs re-routing.

4

Test and advise

Once we've cleared it, we'll run water through and check it's draining fast and smooth. We'll also tell you what caused it and how to prevent it happening again (usually don't pour grease down the sink, use a hair trap, etc.).

Common Causes of Blocked Sinks in Swindon

Grease and cooking oil

Pouring grease, fat, or cooking oil down the kitchen sink is the main cause of blockages. It cools and sets solid in the trap and waste pipe, catching everything else. Wipe greasy pans with kitchen paper and bin it, don't rinse grease down the sink.

Hair in bathroom sinks

Hair washes down the bathroom sink and catches in the trap, forming a mesh that traps soap scum and toothpaste. Over time it builds into a solid mass. Use a hair trap over the plughole, or pull the trap apart and clear it every few months.

Food waste in kitchen sinks

Tea leaves, coffee grounds, rice, pasta, potato peelings, all cause blockages. Modern waste disposal units help, but older Swindon properties don't have them. Scrape plates into the bin before washing them.

Soap scum and toothpaste

Soap and toothpaste combine with hair and limescale to form a sticky sludge in bathroom sink traps. Rinse the sink with hot water after use to help dissolve it, but eventually you'll need to clear the trap manually.

Common Questions

Got questions? Here's the quick answers.

How much does it cost to unblock a sink in Swindon?
Unblocking a sink in Swindon typically costs between £60 and £120. Kitchen sinks with grease buildup may require more work.
Why does my sink keep blocking?
Recurring blockages are usually caused by fat and grease buildup in kitchen sinks, or hair and soap in bathroom sinks. We can advise on prevention after clearing the blockage.
Is a blocked sink an emergency?
Not usually, unless water is overflowing onto the floor. A slow drain can wait for a scheduled appointment, which will be cheaper than an emergency call.
