What this job involves
Replace a damaged floor trap without overlooking the waterproofing interface.
Assessment before agreeing the work
Check drain connection, surrounding tile condition, falls and access below where available.
Scope to confirm in the quotation
Agree trap removal, compatible replacement and the local waterproofing or tiling scope.
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
Review drainage, accessible connections and the agreed reinstatement around the trap.
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.
