The festive season in Johannesburg is a time when many residents lock up their units, head out of town, and leave properties unattended for extended periods. For property management companies, this creates a unique set of risks, particularly when it comes to plumbing. Water-related incidents are among the most common and costly problems reported over December and early January, often discovered only once significant damage has already occurred.

Johannesburg’s summer conditions amplify these risks. Increased water pressure during peak usage times, heavy rain placing strain on drainage systems, and sudden temperature changes all contribute to plumbing failures. When properties are occupied, small leaks or blockages are usually reported quickly. When units are empty, the same issues can escalate into major flooding, structural damage, and costly insurance claims before anyone notices.

One of the most common festive-season plumbing disasters is a slow, unnoticed leak. Worn seals, ageing pipes, or loose fittings may drip steadily for days or weeks in a vacant unit. Over time, water seeps into floors, walls, and ceilings, damaging finishes and encouraging mould growth. In sectional title complexes, this water often travels beyond the affected unit, impacting neighbouring apartments and common property areas, significantly increasing repair costs.

Blocked drains are another frequent issue during the holiday period. In many Johannesburg estates and complexes, summer storms wash debris into drainage systems that may already be partially obstructed. When drains cannot cope with the sudden influx of water, backflow occurs, leading to flooded bathrooms, kitchens, or basements. These incidents are particularly problematic when buildings are empty and response times are delayed.

Water pressure fluctuations also play a role in festive-season plumbing failures. Municipal supply changes, combined with increased usage in surrounding areas, can place additional stress on internal plumbing systems. Older pipes and fittings are especially vulnerable, and failures often occur without warning. A burst pipe in an unoccupied unit can release thousands of litres of water before being detected, causing extensive damage in a short space of time.

Outdoor plumbing is another area that requires attention before residents leave for the holidays. Garden taps, irrigation systems, and external pipework are exposed to the elements and are often overlooked during routine inspections. Leaks in these areas can go unnoticed for long periods, wasting water and undermining foundations or boundary walls. In estates with shared irrigation systems, a single fault can affect multiple properties if not addressed early.

Water heaters and geysers are a well-known source of plumbing disasters during December. Pressure relief valves, ageing tanks, or poorly maintained connections can fail suddenly, releasing large volumes of hot water. In vacant units, geyser failures often cause ceiling collapses and extensive interior damage before they are discovered. Regular inspection and preventative maintenance of these systems significantly reduce the risk of festive-season emergencies.

From a property management perspective, plumbing disasters over the holidays create more than just repair challenges. They disrupt residents’ return from leave, strain relationships with owners and trustees, and place pressure on insurance processes at a time when many service providers are operating with limited staff. Proactive planning helps avoid these scenarios and supports smoother operations during the shutdown period.

There is also an insurance consideration that managing agents cannot afford to ignore. Many insurers assess whether reasonable preventative measures were taken, particularly when damage occurs in vacant properties. Failure to address known plumbing risks or carry out routine maintenance can complicate claims and delay repairs. Documented pre-season inspections provide valuable protection in these situations.

Simple preventative measures can make a significant difference. Identifying and repairing minor leaks, checking valves and joints, and ensuring drainage systems are clear reduces the likelihood of major failures. In some cases, isolating water supply to vacant units during extended absences may be advisable, particularly in older buildings or high-risk areas.

Communication also plays a key role in avoiding plumbing disasters. Clear guidelines for residents, caretakers, and on-site staff help ensure that unusual sounds, water pooling, or pressure changes are reported promptly. Even during the festive season, early detection remains one of the most effective ways to limit damage.

At RM Construction, we work closely with property management companies across Johannesburg to identify plumbing risks before the holiday season begins. Our team understands the common failure points in complexes and estates and focuses on preventative maintenance that reduces the likelihood of water-related emergencies. From inspections and minor repairs to more comprehensive plumbing assessments, we help properties remain secure while residents are away.

As the festive season approaches, now is the time to address plumbing vulnerabilities and protect your buildings from avoidable damage. A proactive approach not only safeguards property assets but also provides peace of mind for managing agents, owners, and residents.
