Signs of a blocked drain
Quick answer
Slow emptying, repeated gurgles or water backing up at another outlet can indicate restricted flow. The pattern matters: one affected fixture suggests a different investigation from several drains failing together.
The useful distinction is between a problem at one fitting and a restriction affecting a connected part of the system. A bathroom basin that drains poorly while the shower and toilet work normally gives a different starting point from wastewater appearing in the shower whenever a toilet flushes. Neither observation proves exactly where the obstruction sits.
Use the comparison below to describe what you can see from a safe place. Do not deliberately flush or run appliances to recreate an overflow. If several properties are affected, establish ownership before paying a private contractor to work on shared drainage.
| What you notice | What needs checking | Useful next step |
|---|---|---|
| One sink or shower drains slowly | The fitting, local waste pipe and its connection | Describe the affected outlet and whether other fixtures still work. |
| Several fixtures back up together | A common downstream run | Stop adding wastewater where it causes overflow and explain all affected rooms. |
| Neighbours have similar problems | A shared or public sewer | Ask Anglian Water about responsibility before commissioning private work. |
| Water pools only during heavy rain | The rainwater outlet, surface levels and onward discharge | Record where water comes from; a blockage is not the only possible cause. |
| The same blockage returns after clearance | Deposits, pipe condition and why flow becomes restricted again | Keep clearance records and consider a scoped camera investigation. |
Drain keeps blocking
What to tell the drainage company
Repeated clearance without an explanation of the cause can leave you paying for the same problem again.
A return visit is most useful when it answers a new question. If the first visit removed an object and the drain has worked normally since, the circumstances differ from a run that repeatedly builds up deposits in the same place. Keeping dates and the recovered material makes that difference visible.
Camera inspection is often more informative once the obstruction is cleared sufficiently for the camera to pass and the pipe wall to be seen. A report should connect any finding to the symptom, identify areas not reached and explain whether maintenance or repair is being proposed. A crack somewhere in the network does not automatically explain every blockage.
- How often the blockage returns and how long clearance lasts.
- Which fixtures are affected and whether neighbours have the same problem.
- What previous visits found or removed.
- Whether you have earlier camera footage or reports.
Kitchen drain blocked
Useful details for your enquiry
Avoid running appliances into a drain that is already overflowing. Food and grease belong in the bin rather than down the sink.
- Is it just the kitchen sink, or do nearby appliances also back up?
- Does water rise when the dishwasher or washing machine drains?
- When did the problem begin, and has it happened before?
Bathroom drain blocked
Hair and soap deposits can restrict bathroom outlets, but several affected fixtures may point further downstream. Describe the bath, shower and basin separately. If the toilet is also affected, mention that before requesting a visit so the investigation is not limited to a sink trap.
Blocked drain overflowing
An overflowing drain needs containment and an ownership check before a clearance quote. Stop using affected outlets if that avoids adding wastewater, keep people away from contamination and record what is affected from a safe position. Several properties affected together can point to a shared system, but symptoms alone cannot establish the asset owner.
For a suspected Anglian Water sewer problem in the Bury area, use its direct reporting route. A road gully belongs in the relevant highway reporting process; a private property drain needs its own assessment. Describe whether overflow follows ordinary use, rain or both. Water entering a cellar is not proof that a blocked sewer is the cause.

Blocked drain smells
Quick answer
A smell alone does not establish a blockage. Its source needs identifying, especially if there is no slow drainage or visible wastewater.
Gurgling drains
Quick answer
Gurgling is a clue to investigate, not proof of a collapsed pipe. Note whether it happens when a toilet flushes, a bath empties or heavy rain begins.
Multiple drains blocked at once
Check the pattern
- List all affected outlets, not just the first one noticed.
- Find out whether nearby homes are affected, if you can do so safely.
- Ask Anglian Water about responsibility if a shared or public pipe may be involved.
What causes blocked drains?
Grease, food, wipes and foreign objects can obstruct drainage; damaged pipework can also contribute to repeated problems. The cause should be supported by what is found during clearance or inspection. A symptom such as a smell is not enough to justify an expensive replacement.
How to unblock a drain
Start by identifying the affected outlets and any overflow, not by adding chemicals. If there is sewage, uncertain access or more than one blocked fixture, request competent help. Never enter an inspection chamber, reach into an unknown blockage or mix drain-cleaning products.
For a single slow fixture with no overflow, start with ordinary maintenance of its accessible strainer or hair trap using the fitting manufacturer’s instructions. The distinction matters: clearing a surface strainer is a household task, while dealing with an unknown underground obstruction needs appropriate equipment and competence.
If several outlets are affected, sewage is visible or the same fault returns, stop treating it as a simple sink problem. Describe the pattern, check responsibility and arrange an assessment. Tell anyone attending about chemical products already used; do not add another product in an attempt to cancel or strengthen the first.
When should you call someone for a blocked drain?
Call for help when water is rising, sewage escapes, several fixtures are affected or the same blockage repeatedly returns. Explain if the household has only one toilet or anyone needs accessible facilities. Our enquiry form is not an emergency dispatch service; urgent public-sewer incidents should go directly to Anglian Water.
How much does it cost to unblock a drain?
Ask whether the quote includes…
Costs depend on access, the type of blockage and urgency. Ask for a quote that explains what is included and when additional work needs your approval.
- Call-out and VAT.
- The equipment needed to clear the obstruction.
- A camera check, if required, or a separate charge for investigation.
- Additional time and any return visit.
Who is responsible for a blocked drain?
Before commissioning clearance
Establish which pipe is affected, which properties it serves and whether it is adopted. Anglian Water explains that many older shared runs are its responsibility, while post-2011 development arrangements can differ. A pipe crossing your garden is not automatically yours to repair. Ask the operator about uncertain shared or public assets before paying for private intervention.
For a Bury St Edmunds rented or managed property, tell the actual landlord or manager first. Havebury residents have their own reporting route; other landlords use their own arrangements. Do not assume the district council manages the home or that a tenancy decides underground sewer ownership. A quotation should identify the private work that you can authorise.
- Identify the affected fixtures and neighbouring properties.
- Check private, shared or adopted status.
- Confirm the landlord or manager can authorise the proposed work.

Blocked drain on rented property
Notify your landlord or letting agent promptly and record the symptoms. Ask who should arrange attendance before commissioning non-emergency work yourself. A rented address does not change public-sewer ownership; shared-sewer problems can still need Anglian Water rather than a private repair.
