24/7 drain unblocking and drainage help in Southampton from Petersfield-based SouthFlow. Explore clearance, CCTV surveys and repair services.

Local Drainage Support
Across all of Hampshire,
Surrey & West Sussex
Start with the symptoms at your address
Tell SouthFlow which outlets are affected, when the problem began and whether wastewater is staying contained. A slow sink, rising toilet and overflowing outside drain can require different enquiries, especially when several appear together.
SouthFlow provides 24/7 drainage help across Southampton as part of its Hampshire coverage. The business is based in Petersfield and carries £5 million public liability insurance.
Urgent drainage help
If sewage is backing up or essential facilities cannot be used, describe the situation clearly when arranging attendance. Explain whether water is entering the property and whether other facilities are available.
Avoid repeatedly flushing a toilet that is rising or not emptying. Keep people and pets away from overflowing wastewater. Provide the full postcode and explain access restrictions so attendance arrangements can be discussed.

Explore the Southampton service →Check the appropriate contact
If you rent or the affected area is managed, contact the landlord or managing agent about access and authorisation. Where the issue may involve a shared sewer or road drainage, check the appropriate reporting route before instructing private work.
Use GOV.UK’s blocked-drain reporting guidance or Southampton City Council’s road-drain reporting information to find the relevant route.
A repeating blockage needs a fuller explanation
Share the date of earlier clearance, how long it helped and what was found. A camera inspection may help investigate visible pipe condition where the problem returns. Clearance restores flow; structural damage may need a separate repair assessment.
For a property purchase, explain the evidence your advisers require. Agree the inspection extent, access and outputs before booking rather than assuming a basic look at the drain meets every requirement.

Your Southampton service questions
Do you offer 24/7 drainage help?
Yes. SouthFlow provides 24/7 drainage help. Tell us where the problem is, whether wastewater is overflowing and how essential facilities are affected. Attendance arrangements are confirmed for the individual enquiry.
Where is SouthFlow based?
SouthFlow is based in Petersfield and covers Hampshire, Surrey and West Sussex. A town page describes our coverage; it does not mean we have a separate branch in that town.
Should I book clearance or a CCTV survey?
Clearance addresses a restriction, while CCTV inspection investigates visible condition inside accessible pipework. Describe the symptoms and any previous problems first so the appropriate next step can be discussed.
What should I do if wastewater is overflowing?
Avoid adding more water through affected outlets where that worsens the overflow. Do not repeatedly flush a blocked toilet, and keep people and pets away from wastewater.
Does a blocked drain always need a repair?
No. A blockage can occur without structural damage. If a defect is suspected or the restriction keeps returning, inspection may help establish whether repair is needed.
What information helps when requesting help?
Provide the full address and postcode, the affected outlets and when the problem started. Include previous findings, access restrictions and the contact who can authorise work at a rented or managed property.
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.
