What this job involves
Replace a leaking or unsuitable accessible trap below a sink or basin.
Assessment before agreeing the work
Check pipe sizes, trap geometry, waste alignment and available cabinet clearance.
Scope to confirm in the quotation
Fit a compatible trap arrangement and check accessible waste joints.
How the cost is assessed
The visible fitting is only one part of a plumbing job. The connection, isolation valve, pipe route, drainage arrangement and access to concealed areas can change the repair needed. Describe where the problem appears and whether it occurs continuously or only while a fitting is being used.
- Type and location of the fitting, pipe or drainage connection
- Accessibility of valves, traps and concealed pipework
- Condition of adjacent tiles, cabinets and waterproofing
- Parts compatibility and the extent of testing after installation
The final scope and price depend on the site assessment, quantities, chosen materials and agreed exclusions. Ask for an itemised quotation rather than assuming a standard rate covers every condition.
Before the site visit
- Send a wide photograph of the fitting and a close-up of the affected connection.
- Note whether the problem affects one fitting or several.
- Identify the water isolation point if it is safely accessible.
Water-service and sanitary plumbing work may require a PUB Licensed Plumber. Confirm the appointed person and the permitted scope before starting. If water is near electrical equipment, keep clear and arrange safe isolation by the appropriate professional.
Check the completed work
Run the fitting and inspect visible joints, drainage and the completed trap arrangement.
Agree which records, material details and follow-up items will be handed over. Record any area outside the agreed scope so it is clear what has been inspected and what still needs attention.
