Identify the affected sink and water pattern
A kitchen sink that holds water and a basin that backs up when another outlet is used may involve different parts of the waste route. Describe the pattern for your Bishop’s Waltham enquiry, including smells, gurgling and any symptoms at outside drains.

Explain earlier attempts and recent changes
Tell us when the problem began, whether waste pipework has been altered and what previous clearance found. Mention trap cleaning and products added. If symptoms returned quickly, explain how long the improvement lasted so the wider connected route can be considered.
Confirm the clearance extent
Ask whether the proposed work concerns the sink waste alone, outside drainage or further inspection. Supply access details and any restricted working space. Agree attendance, investigation and clearance charges, including how additional work would be authorised if findings change the scope.
Your Bishop’s Waltham 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.
