What blocked sink clearing involves
Blocked sink clearing covers grease and food in kitchen wastes and hair and soap in bathroom wastes. If several fittings are slow or the outside gully is overflowing, a drainage specialist may be needed instead.
Common reasons for an enquiry
- A sink, basin or bath that drains slowly or holds water
- Gurgling from a plug hole when another fitting drains
- Water rising in the sink when an appliance empties
- A sour or sewage smell from a plug hole
- Drips from the trap or waste joints
- A sink that blocks again soon after being cleared
What a plumber may do
- Confirm the blockage is in the waste rather than the drain
- Remove and clean the trap
- Feed an auger through the pipe to break up the blockage
- Flush the waste with hot water and check it drains freely
- Check every joint under the sink before leaving
If you have used a chemical cleaner, tell the plumber before they open the pipe. Standing water with chemicals in it is hazardous to handle.
Details that help a plumber price the job
List every fitting that drains slowly and say whether the outside gully is full. Explain what has been tried, especially any chemical cleaner, and whether a dishwasher or washing machine shares the waste. Mention if the trap is hidden behind a kickboard or bath panel.
If the sink blocks regularly, ask for the cause to be checked as well as the blockage cleared. Clear the cupboard under the sink before the visit.
Tell the plumber what has already been tried
Mention any drain chemicals and keep the packaging so the plumber can choose safe equipment and protection. Several slow fittings, outside overflows or recurring backups may point beyond the trap to a larger drainage problem.
What to check at handover
After clearance, the plumber can run water, check disturbed joints and inspect the waste route for poor falls or unsupported pipework. Ask for removed deposits to be contained and the cupboard wiped down rather than washed back into the waste.
Guide costs for blocked sink and waste pipe clearing in Llantwit Major
The site’s UK guide range for this service is £75–£250. This is not a measured average for Llantwit Major or a fixed offer. Confirm whether the price includes VAT, parts and call-out time.
Clearing the trap sits at the lower end of the range. Using an auger along the waste run costs more, and replacing a trap or re-laying a section of waste pipe sits at the top. Blocked underground drains are priced separately.
Ask for any extra work to be explained and agreed before it starts.
Check the requirements before work starts
Cleaning an existing trap is different from altering drainage. New waste routes, connections or underground work may need building control checks; Approved Document H is England’s drainage guidance. The equivalent requirements elsewhere in the UK differ. Ask a drainage specialist or water company about a suspected shared or public sewer blockage rather than assuming it is private sink pipework.
Fat and grease poured down sinks also cause problems in public sewers. Vale of Glamorgan Council can advise on household waste and food waste collections in your area.
Checks before appointing a plumber
Ask whether the price is fixed or hourly, what happens if the drain is blocked and whether the plumber will explain the cause. WaterSafe lists plumbers who belong to approved contractor schemes, which you can use to check a business.
Compare whether parts such as new traps are included.

Before you book: plumbing questions
For a property in Llantwit Major, confirm the scope with the business that will do the work.
How much does it cost to clear a blocked sink in Llantwit Major?
The site’s guide range is £75 to £250. Clearing the trap sits at the lower end, using an auger along the waste run costs more, and replacing a trap or re-laying a section of waste pipe sits at the upper end.
How can I tell if the drain is blocked rather than the sink?
If only one fitting is slow, the blockage is probably in its trap or waste pipe. If several fittings are slow at once or the outside gully overflows, the underground drain is more likely to be blocked.
Can I keep using the sink until the plumber arrives?
Avoid it if water is standing in the sink, and do not run the dishwasher or washing machine if they share the waste, as they may push more water back up.
How can I stop my sink blocking again?
Scrape plates into the bin, wipe greasy pans before washing and use a plug hole strainer. If it still blocks often, ask a plumber to check the trap, the slope of the waste pipe and any appliance connections.
