A freshly painted bathroom tells you little about the pipes behind it. Before buying a Johannesburg home, a plumbing inspection can help you understand visible defects, practical maintenance needs and areas that require further investigation. It should have a clear scope so that you know what was checked and what remains unknown.
This checklist is useful when discussing a freestanding house, townhouse or sectional-title unit with the seller and your chosen plumber. It is a starting point for an assessment, not a guarantee that every concealed defect will be found.
Start with the property’s repair history
Ask about past leaks, drain blockages, geyser replacements and bathroom alterations. Request available invoices, warranties, inspection records and details of the contractors involved. An explanation supported by records is more useful than a general statement that the plumbing was “recently done”.
Ask specifically whether the same problem has returned. Repeated clearing of one drain or repeated patch repairs in one area can justify closer investigation before deciding on a repair budget.
Observe accessible fixtures and connections
With the seller’s permission, ask the plumber to assess taps, toilets and accessible waste connections. Useful observations include dripping fittings, running cisterns, slow drainage, staining beneath cupboards and moisture around sanitaryware.
Water pressure and flow should be interpreted in context. A temporary supply interruption can affect an inspection, while a problem confined to one fitting may have a different cause. Record any limitation rather than accepting a single quick tap test as proof of the entire system’s condition.
Discuss the geyser and hot-water system
Ask where the geyser is located, how it is accessed and which records are available. The inspection should be undertaken safely by an appropriate professional; a prospective buyer should not climb into a difficult roof space or remove electrical covers.
Clarify whether the assessment includes accessible valves, signs of leakage and the hot-water system’s general condition. If specialised compliance checks or electrical work are needed, ask who will perform them and what documentation will be supplied.
Do the drains need further investigation?
Slow drainage, persistent odours or a history of recurring blockages deserve specific questions. A camera inspection may be worth discussing where the symptoms and access justify it. It is not automatically included in a general visual inspection.
Ask the plumber to explain what the proposed test can establish, which sections can be reached and whether clearing is required first. Our guide to drain jetting, rodding and camera inspections explains these different purposes.
Check shared systems and access
For a complex, ask the managing agent which systems serve the unit and which are shared. Establish how plumbers obtain access, where isolation points are located and who coordinates faults affecting neighbouring units. Responsibility should be confirmed from the relevant property arrangements rather than assumed.
If the home has a tank, pump, irrigation system or other additional equipment, list it separately in the inspection scope. A standard fixture check may not cover its operation or suitability.
Request a written, prioritised report
- Which defects need urgent attention?
- Which items are maintenance rather than immediate repairs?
- What could not be inspected, and why?
- What additional tests are recommended?
- Does the estimate include access work and reinstatement?
Keep the report and quotations with the purchase records. Discuss any contractual decisions with the appropriate property professional; a plumbing report provides technical findings, not legal advice about the sale.
