Explain when the sink backs up
Tell SouthFlow which sink is affected and whether the problem occurs on every use or only intermittently. Include any gurgling, smells or water backing up when another outlet is used. This helps distinguish a local waste restriction from a wider drainage issue.

Previous work can help explain the pattern
If clearance has already been attempted, describe what changed and how long the improvement lasted. Mention products used before work begins. Repeated symptoms may call for investigation of the drainage route rather than another isolated treatment of the sink.
Know the scope before work starts
Ask whether the quote covers the sink waste, connected drainage, or additional investigation. Access and the restriction affect the method and price. Supply the full address and working-space details, and explain whether another person needs to provide entry to the premises.
Your Southampton service questions
Do you clear kitchen sinks and bathroom basins?
Yes. Tell us which outlet is affected and whether it drains slowly, holds water or backs up when another outlet is used.
Why does my sink keep blocking?
Build-up in the waste route or a restriction further downstream may be involved. If the problem returns after clearance, share the history so the connected drainage can be considered.
What if other outlets are backing up too?
Report all affected outlets together. Several symptoms at the same time can indicate a restriction further along a connected drainage route rather than a problem confined to the sink trap.
Should I mention unblockers I have already used?
Yes. Tell us which products were used and whether standing water remains before anyone handles the waste pipe. Also mention trap cleaning or other attempts to clear it.
Does the service include the outside drain?
That depends on where the restriction lies and the work agreed. Ask whether the quote covers only the sink waste or includes connected external drainage and any investigation.
Can you help outside normal hours?
Yes. SouthFlow provides 24/7 drainage help. Explain the symptoms and their impact, then confirm attendance arrangements and charges for your address.
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.
