Quick answer
A backup water supply system stores water in a tank and uses a suitable pump to supply selected fixtures or your property's plumbing when municipal water is unavailable. For a Brakpan home or business, the right setup depends on essential water use, available space, incoming supply and power for the pump. Fox Plumbing serves Brakpan from Benoni and can assess your requirements before agreeing the price upfront.
When a backup water system makes sense
Consider backup storage if water interruptions leave you unable to flush toilets, wash or keep essential business facilities working. It can also help where an unreliable incoming supply disrupts daily routines, provided there is enough opportunity for the tank to refill between interruptions.
First establish whether the problem is the municipal supply or your own plumbing. A leak, blocked strainer or faulty pressure-control valve needs attention rather than a bigger tank. Storage is a finite reserve: how long it lasts depends on usable capacity and how carefully you use it.
- List essential uses, such as toilets, handwashing, cooking and limited showering.
- Decide whether you need to supply the whole property or only selected fixtures.
- Check whether neighbours also lose supply when your water stops.
- Plan to reduce non-essential use, including irrigation, during an interruption.
What affects the cost of backup water storage
Tank capacity is only one part of the installation cost. A suitable base, delivery access, pipe routes, pump selection and safe separation from the municipal supply all affect the work required. A narrow side passage or a tank position far from the incoming water line can change the scope considerably.
Pump selection should account for simultaneous demand, pipe resistance and height differences—not simply the number of bathrooms. If the system must work during a power cut, provision for a compatible backup electricity supply also needs to be considered.
- Tank size, number of tanks and access for delivery.
- Ground preparation and a level base suitable for the full tank load.
- Pipe lengths, isolation valves, overflow routing and backflow protection.
- Pump duty, controls, dry-run protection and pressure requirements.
- Electrical work, backup power and any water-quality treatment required.
Practical planning for a Brakpan property
Assess the actual conditions at your Brakpan address rather than choosing a system on a general promise about outage duration. Record how much water you need for essential tasks and discuss a realistic reserve period. Leave space around the tank for inspection, cleaning and access to valves, and position the pump with noise and weather protection in mind.
Use a covered tank suitable for the intended water use, with protected openings and a safely routed overflow. Regular turnover helps avoid prolonged storage, but does not guarantee drinking-water safety. Rainwater and borehole water need separate assessment, appropriate testing and treatment before drinking use; they must not be allowed to contaminate the municipal supply.
- Confirm applicable municipal requirements before connecting the system.
- Provide suitable backflow protection; stored water must not feed into the municipal main.
- Plan pump power separately from water storage.
- Keep the tank accessible for inspection and cleaning.
- Do not assume a basic sediment filter makes unsafe water drinkable.
Discuss your system with Fox Plumbing
Fox Plumbing is based in Benoni and serves the East Rand, including Brakpan, and greater Gauteng. Owner Evan Pretorius is a qualified registered plumber with more than 20 years' experience, is a member of IOPSA and PIRB, and issues Certificates of Compliance (COCs). He remains on the tools.
The price is agreed upfront, the call-out fee includes the first hour of work, and every job is insured. Pensioners receive a special rate. Phone 084 368 1879 to discuss your property and arrange an assessment. Hours are Monday to Friday, 08:00–17:00, with Saturdays by appointment.
- Explain whether you need household backup or water for essential business facilities.
- Share photographs of the proposed tank space and incoming water connection.
- Mention existing tanks, boreholes, rainwater connections and backup electricity.
- Ask what compliance documentation applies to the agreed work.
How we do the job
- 1
Assess demand and the existing supply
Identify essential fixtures, likely simultaneous use and the reserve period you want. Check incoming pressure and flow, and investigate plumbing faults that could be mistaken for a supply problem.
- 2
Choose storage and a suitable location
Size the usable reserve around expected consumption. Check delivery access, ground conditions, manufacturer base requirements, overflow drainage and maintenance space.
- 3
Design the connections and controls
Specify a pump suited to the required flow and pressure, along with tank filling controls, isolation valves, dry-run protection and appropriate backflow protection. Decide whether supply changeover will be automatic or manual.
- 4
Prepare the base and install the equipment
Position the tank on its prepared support and connect the agreed pipework and pump. Arrange any required electrical work through a suitably qualified electrical professional.
- 5
Test normal operation and an interruption
Check for leaks, confirm filling and overflow operation, and test fixture pressure. Simulate loss of incoming water and verify the controls, low-water protection and changeover arrangement.
- 6
Hand over operating and maintenance instructions
Explain the valves, pump controls and what happens during a power cut. Set out inspection and cleaning needs, and confirm the applicable compliance documentation.
Common questions
What size water tank do I need? +
Base the size on essential daily consumption multiplied by the number of days you want to cover, allowing for unusable water below the outlet or pump cut-off level. Available space, refill rate and peak demand also matter. Household size alone is not enough to select a tank.
Will the system work when the electricity is off? +
An electrically driven booster pump needs power. A tank can still contain water while your taps have no useful pressure. Discuss compatible backup power, including the pump's starting requirements; gravity supply only works where the installation provides sufficient height and suitable plumbing.
Does backup water switch on automatically? +
It can, depending on the design. Some systems supply the property through the tank and pump continuously; others use a changeover arrangement. A tank's filling valve controls refilling, not necessarily the changeover to backup supply.
Is stored municipal water safe to drink? +
Storage alone does not guarantee safety. The incoming water quality, tank suitability, protected openings, cleanliness and storage time all matter. Follow any official water-quality notices and seek testing or treatment advice if contamination is suspected.
Can I connect a borehole or rainwater tank to the same plumbing? +
Do not simply join these sources to drinking-water plumbing. They need assessment for water quality, treatment, cross-connection risks and applicable requirements. Clearly separated non-potable supplies may be more appropriate for uses such as irrigation or toilet flushing.
