Quick answer
Look for visible leaks, staining, corrosion, poor drainage and signs of past repairs, but do not treat a viewing as a full plumbing inspection. Ask about known issues and use a qualified surveyor or plumber where concerns need investigation.
Look and listen during a viewing
Check accessible areas beneath sinks, around toilets, beside baths and near appliances for dampness, swollen cabinets, staining or a musty smell. Look at ceilings below bathrooms for discolouration or bubbling finishes. A dry surface on viewing day does not prove there has never been a leak, and decorative work can conceal previous damage.
Notice whether taps and toilets operate normally and whether sinks, baths and showers drain without obvious backing up. Ask permission before operating unfamiliar controls. Do not remove panels, lift flooring or dismantle fittings during a viewing.
Ask useful questions
- Has the property had leaks, flooding, pipe repairs or an insurance claim? Ask what was repaired and whether documentation is available.
- Are there known issues with water pressure, drainage, boiler operation or recurring damp?
- When were visible pipes or heating components last maintained, and are service records available?
- Where is the stopcock, and does it operate? Ask for access rather than forcing it yourself.
Know the limits of a viewing
A viewing cannot confirm the condition of concealed pipework, the inside of a boiler or drainage underground. A property survey may note visible concerns, but its scope varies. Ask the surveyor what is included and whether specialist plumbing or drainage checks are appropriate. If a leak is suspected, inspection may require targeted testing rather than guesswork.
If there is an unexplained damp patch, do not assume it is harmless condensation or a historic problem. Ask for evidence of the cause and repair, and consider an independent assessment before proceeding. TraceFix engineers in Birmingham and London can investigate plumbing leaks and provide findings for a property concern.
