Toilet Unblocking in Hampshire
Blocked, slow-flushing or overflowing toilet? SouthFlow provides 24/7 toilet unblocking across Hampshire.

Local Drainage Support
Across all of Hampshire,
Surrey & West Sussex
A blocked toilet or a wider drainage restriction?
A rising toilet bowl, repeated blockage or wastewater returning through other outlets can require different investigation. Stop flushing if the water level is rising and tell SouthFlow whether another toilet is usable. Describe any overflow and keep occupants away from escaped wastewater while arranging help.
For a Hampshire toilet-unblocking enquiry, explain whether the issue is confined to one fixture or affects connected drainage. Share known flushed objects, earlier clearance attempts and products already added. Recurring problems may justify a separate camera investigation, rather than assuming repeated clearance will address a structural defect.
Arrange toilet unblocking at your Hampshire address
SouthFlow is based in Petersfield and covers Hampshire homes, landlords and commercial premises. Provide the full address and postcode, access restrictions and the purpose of the work. For urgent help, call 07922 321154. For planned work and supporting information, email info@southflowdrainage.co.uk.
The price depends on the work needed, access and any preparation or investigation. Ask what the quote includes, including attendance, cleaning, inspections and records where relevant. Discuss timing directly and agree approval for work beyond the initial scope before it proceeds.
Help with a blocked toilet
A restriction may be in the toilet’s waste route or further along the connected drainage. Tell us whether one toilet is affected or several outlets are backing up. This helps distinguish an isolated issue from a wider drainage problem.
SouthFlow is based in Petersfield, covers the whole of Hampshire and provides 24/7 drainage help. The business carries £5 million public liability insurance.
When to enquire about toilet unblocking

- Repeated toilet blockages.
What happens next?
Tell us what is affected
Provide the property postcode and describe the toilet problem, including whether other outlets are backing up.
Discuss access and assessment
The position of the restriction and available access determine the appropriate approach.
Investigate recurring problems
If a blockage keeps returning, further drainage investigation or repairs may need to be considered.
What affects the cost of toilet unblocking?
The location of the restriction, access, the work required and attendance time all affect the job. Explain the symptoms when requesting a quote and ask which work and charges are included.
Your questions answered
What should I do if my toilet is blocked?
Avoid flushing again if water is not leaving the bowl. Keep people and pets away from any wastewater overflow. When contacting us, explain whether this is the only usable toilet.
Can the blockage be in the outside drain?
Yes. A restriction further along the drainage route can cause the toilet to back up. Mention other affected toilets, gurgling sinks or outside overflows so the wider pattern is considered.
Why does the toilet keep blocking?
There may be a persistent restriction or an underlying issue further along the drain. Share previous clearance findings and how soon symptoms returned; further investigation may be useful.
Will I need a CCTV survey?
Not every toilet blockage needs a survey. The symptoms, clearance findings and history will help determine whether camera inspection of connected drainage would be useful.
What should I tell you before the visit?
Give the full address, describe the water level and any overflow, and mention products used or items accidentally flushed. Explain any access restrictions and who can authorise the work.
Is help available at night or at weekends?
Yes. SouthFlow provides 24/7 drainage help. Confirm attendance arrangements and charges for your enquiry rather than assuming a particular arrival time.
How much does the work cost?
We quote for the work your property needs. The price depends on the problem, access, preparation and attendance arrangements. When requesting a quote, ask what is included and whether VAT or additional investigation charges apply.
