When a pipe leaks, a geyser fails, or a circuit breaker trips and refuses to reset, most homeowners face the same immediate concern: what is wrong, how serious is it, and what should I do next? Having clear, reliable answers helps you respond calmly, make informed decisions, and avoid actions that can make a plumbing or electrical fault worse before a professional arrives.
YEPI Plumbing & Electrical has compiled honest, practical answers to the questions Johannesburg homeowners, landlords, and property managers ask most frequently. These questions reflect the most common plumbing faults, electrical problems, and property maintenance concerns our technicians encounter across Johannesburg every week.
This FAQ covers twelve common questions across plumbing, electrical, and compliance topics. If your specific question is not listed here, call or WhatsApp us directly and we will give you straightforward advice at no cost.
This is the first question most homeowners ask, and the honest answer is that plumbing costs depend entirely on what the fault actually is. A visual inspection of the problem is the only way to give an accurate price — general estimates without seeing the fault are rarely reliable.
Straightforward repairs — fixing a dripping tap, replacing a toilet flush valve, or clearing a minor drain blockage — are typically completed quickly and cost less. More involved work such as geyser installation in Johannesburg, burst pipe repair, concealed leak detection, or drain unblocking requiring specialist equipment naturally takes more time and materials.
At YEPI Plumbing & Electrical, we assess the problem first and explain the full scope of work and cost before any work begins. You will not encounter unexpected charges or hidden call-out fees.
A standard residential geyser installation in Johannesburg typically takes between 2 and 4 hours. This covers draining and disconnecting the old unit, fitting and securing the new geyser, connecting both the plumbing supply and the electrical feed, fitting or checking the pressure and temperature relief valve, installing a drip tray if required, and fully testing the system before completion.
Installation may take slightly longer if the ceiling space is difficult to access, if the existing pipework requires modification, or if additional components such as an isolator valve, vacuum breaker, or pipe fittings need replacing at the same time.
Professional geyser installation by a qualified plumber ensures the unit is safely connected, performs correctly, and retains its manufacturer warranty. Incorrectly installed geysers frequently void the warranty and can present serious safety risks.
Most residential geysers installed in Johannesburg homes have a working lifespan of 8 to 12 years. Properties in areas with high-mineral or hard water may experience shorter lifespans because scale accumulation inside the tank accelerates corrosion and reduces heating efficiency. Annual testing of the pressure and temperature relief valve helps extend the unit's life.
The following signs indicate the geyser should be professionally assessed, as repair may no longer be cost-effective:
• Water leaking from the tank body itself — not from a valve connection or pipe fitting
• Rusty or brown-tinted water from the hot tap, indicating internal corrosion of the tank lining
• Hot water running out noticeably faster than it used to
• Loud popping, rumbling, or banging sounds during the heating cycle — typically caused by sediment on the element
• The geyser requiring repeated repairs within a short period
• A significant unexplained increase in electricity consumption
A professional plumber can inspect the unit and give you an honest assessment of whether repair or full replacement is the better investment at that stage of the geyser's life.
Blocked drains are among the most frequent plumbing call-outs across Johannesburg. Most blockages develop gradually through accumulation rather than a single event. In kitchen drains, the primary cause is a progressive buildup of cooking grease, oil, food particles, and detergent residue coating the inside of the pipe. In bathroom drains, hair and soap scum are the most common culprits. In toilets, the most damaging blockages come from non-flushable items — wet wipes, cotton buds, and sanitary products that do not break down.
Outdoor drains can become blocked by leaves, soil, and in older Johannesburg properties, tree roots that have grown into the drainage pipe. If multiple drains in your property are running slowly at the same time, this usually indicates a blockage in the main drain line rather than individual fixtures — requiring professional drain unblocking with the correct equipment to clear properly.
Concealed leaks inside walls, beneath floors, or underground are more common in Johannesburg properties than most homeowners realise. They can go undetected for months or even years while causing progressive structural damage and inflating water bills. The most reliable early indicator is a water bill that has increased noticeably without any change in usage.
Other signs that a hidden leak may be present:
• Damp or discoloured patches on walls or ceilings that do not dry out over time
• Soft, warped, or stained flooring near bathrooms, kitchens, or utility areas
• The continuous sound of running water when all taps and appliances are off
• Mould growth or a persistent musty smell without a visible moisture source
• A gradual drop in water pressure throughout the property
• The water meter dial moving when no water is in use
Leak detection in Johannesburg using professional diagnostic equipment allows a qualified plumber to locate the exact position of a concealed leak without unnecessary damage to walls or floors. Early detection significantly reduces both repair costs and structural damage.
Low water pressure affecting the whole property — rather than just one tap — usually points to a fault in the water supply line, a partially closed or faulty main stop valve, a pressure regulator that has failed, or a leak somewhere in the supply pipe that is diverting water before it reaches the fixtures.
In Johannesburg, older properties with galvanised steel supply pipes sometimes experience progressive reduction in pressure as internal corrosion and scale buildup narrow the pipe bore over time. In these cases the pipe section may need to be replaced rather than simply repaired.
Common causes of whole-property low water pressure include:
• A partially closed isolator valve or main stop valve reducing flow
• A faulty or incorrectly set pressure-reducing valve on the supply line
• A concealed leak in the main supply pipe diverting water before it reaches taps
• Scale or corrosion buildup narrowing the inside diameter of older pipes
• Supply pressure issues from the municipality affecting the area
A qualified plumber can diagnose the cause of low water pressure accurately and advise on the most appropriate repair. Do not ignore persistent low pressure — it often indicates a supply line fault that will worsen over time.
A circuit breaker that trips repeatedly is a clear signal that something in the circuit requires professional attention. The breaker is functioning correctly — it is protecting the wiring from damage — but the underlying fault causing it to trip needs to be identified and repaired by a qualified electrician in Johannesburg. Resetting the breaker repeatedly without addressing the cause is unsafe.
The most common reasons a breaker trips persistently include:
• Circuit overload — too many high-draw appliances running on a single circuit simultaneously
• A short circuit in the wiring or within a connected appliance
• Earth leakage — moisture entering a fitting or appliance creating an unintended earth path
• Deteriorating wiring that develops a fault when under load
• An ageing DB board breaker that trips at lower current levels than it should
Electrical fault finding by a qualified electrician identifies the exact cause and resolves it correctly. If the breaker trips more than once without an obvious explanation, arrange a professional inspection.
A DB board repair involves diagnosing and fixing a specific fault within an existing distribution board. Common faults include a failed breaker, a loose terminal connection, a damaged neutral bar, or an earth leakage unit that is tripping incorrectly. In most cases, DB board repair in Johannesburg resolves the problem without the need to replace the entire board.
A DB board installation refers to fitting a completely new distribution board. This is typically needed when the existing board is outdated, physically damaged, too small for the property's current electrical load, or non-compliant with current South African standards. Distribution board installation is also carried out as part of new builds and major renovations.
Both services must be carried out by a qualified electrician. Attempting to work on a distribution board without the correct credentials and safety equipment is dangerous and contravenes South African electrical regulations.
Yes, in specific circumstances an Electrical Compliance Certificate is a legal requirement. When selling a property in South Africa, the seller must provide the buyer with a valid COC confirming that the electrical installation has been inspected by a registered electrician and meets current safety standards. Without this certificate, the property transfer cannot be legally registered.
A COC is also required after significant electrical work — such as DB board installation, house rewiring, or the addition of new circuits. Landlords may be required to provide one for rental compliance, and insurers may request it following an electrical incident. YEPI Plumbing & Electrical carries out both the inspection and any required pre-certification repairs.
Occasional flickering from a single light fitting is often caused by a loose bulb, a faulty lamp, or a worn light socket. However, flickering that affects multiple lights, or that occurs noticeably when certain appliances are switched on, usually indicates a more significant electrical fault that requires professional inspection.
Common causes of persistent or widespread flickering include:
• A loose wiring connection at the fitting, switch, or within the distribution board
• An overloaded circuit that drops in voltage when additional load is applied
• A failing or corroded DB board connection causing voltage instability on that circuit
• Deteriorating wiring that develops resistance under load, causing a voltage drop
• Voltage fluctuations from the municipality supply affecting the property
If flickering is persistent, affects more than one light, or is accompanied by other symptoms such as warm outlets or a burning smell, contact a qualified electrician for an electrical inspection. Left unaddressed, the underlying fault can damage appliances or develop into a more serious wiring problem.
Most properties do not need a complete rewire, but older Johannesburg homes — particularly those built before the 1990s — may have wiring that is no longer adequate for modern electrical demands, or that has deteriorated with age to a point where it presents a safety risk.
Signs that a property may need rewiring or a wiring assessment include:
• Rubber or cloth-insulated wiring visible in the roof space, under floors, or in wall cavities — typical of older installations
• Circuit breakers that trip regularly without a clear cause across multiple circuits
• Burning smells from outlets, switches, or walls that have no obvious source
• An electrician being unable to issue a COC due to non-compliant wiring
• A property that has had no electrical assessment in more than 10 to 15 years
• Visible scorch marks or discolouration around plug points or light fittings
• Persistent problems with power in specific areas of the property despite breaker checks
A professional electrical inspection by a qualified electrician in Johannesburg will confirm the condition of the existing wiring and identify exactly what work, if any, is required. YEPI Plumbing & Electrical carries out wiring assessments, electrical fault finding, and house rewiring for residential and light commercial properties across Johannesburg.
