Quick answer
A backup water supply system stores water in a tank and supplies selected taps or your building’s plumbing through a suitably sized pump. For a Springs home or business, the right setup depends on essential water use, available tank space, existing plumbing and whether the pump must work during power cuts. Fox Plumbing serves Springs from Benoni and can assess your requirements before agreeing the price upfront.
When a backup water supply makes sense
Consider backup storage if water interruptions leave you unable to flush toilets, wash or keep essential business facilities running. It is also useful when buying and carrying bottled water has become an impractical way to manage interruptions.
First establish whether the problem is a supply interruption or a fault on your property. A blocked strainer, leaking pipe or faulty valve can cause poor flow even when municipal water is available. A tank does not repair these problems, and an unresolved leak can drain your reserve.
- List essential uses before deciding whether to supply the whole property.
- Identify which taps, toilets and appliances must remain usable.
- Check for unexplained water loss before sizing the reserve.
What affects installation cost
Tank capacity is only one part of the cost. The installation must also accommodate the tank’s full weight, deliver suitable pressure and prevent stored water from flowing back into the municipal supply. Restricted access or long pipe routes can make a seemingly simple installation more involved.
Ask for a clearly defined scope covering plumbing, controls, base preparation and any separate electrical work. Fox Plumbing agrees the price upfront; clarify what is included before work starts.
- Usable storage capacity and the number of tanks needed.
- Ground preparation and a level base meeting the tank manufacturer’s requirements.
- Pump flow, pressure, controls and dry-run protection.
- Pipe lengths, isolation valves and appropriate backflow protection.
- Electrical supply, weather protection and any compatible backup power.
- Water-quality requirements, access and alterations to existing plumbing.
Practical planning for a Springs property
For a Springs installation, confirm applicable City of Ekurhuleni requirements before connecting storage to municipal plumbing. The design must prevent backflow; do not assume a single non-return valve is sufficient for every arrangement. Municipal-water storage and rainwater harvesting also have different water-quality requirements and should not be casually interconnected.
Choose a tank position with safe access for inspection and cleaning, a suitable overflow route and room to service the pump. Allow for Gauteng’s cold winter conditions when protecting exposed pipework. If water and electricity are both unavailable, a standard electric pump will not operate without a suitable alternative power supply.
- Check delivery access as well as the tank’s final footprint.
- Keep overflow water away from foundations and neighbouring properties.
- Consider pump noise near bedrooms and boundary walls.
- Use a covered tank suitable for the intended water use, with protected openings.

How we do the job
- 1
Establish demand and reserve time
Estimate essential daily consumption and decide how long you want the reserve to last. Size usable storage around those needs rather than choosing a tank by appearance or available space alone.
- 2
Inspect the site and existing plumbing
Check access, ground support, incoming supply, pipe condition and the fixtures to be served. Identify leaks or restrictions that should be addressed before connecting the system.
- 3
Agree the design and scope
Choose the tank capacity, pump duty and manual or automatic operating arrangement. Specify backflow protection, isolation valves, dry-run protection and any electrical work, then agree the price.
- 4
Prepare the base and install components
Provide a level, load-bearing base to the tank manufacturer’s specifications. Position the tank and pump for maintenance access, then install supported pipework, filling controls and a safely routed overflow.
- 5
Connect, clean and commission
Complete the plumbing and arrange any required electrical work through a qualified electrician. Clean and flush the system as appropriate, check for leaks and verify that operating pressure suits the connected plumbing.
- 6
Test interruption behaviour and explain maintenance
Simulate a supply interruption and check delivery, controls and low-water protection. Explain valve positions, power requirements, cleaning and inspection needs, and provide applicable compliance documentation.
Common questions
How long will a backup tank supply my property? +
Divide the usable stored volume by your essential daily consumption to estimate reserve time. The result depends on occupancy, toilet use, showers, appliances and leaks. Allow for water that the pump cannot draw and reduce non-essential use during an interruption.
Will the system switch over automatically? +
It can be designed for automatic operation, but this depends on the plumbing layout and controls. Some systems normally supply the property through the tank and pump, while others use a changeover arrangement. Confirm how the proposed system behaves during municipal outages, power cuts and an empty-tank condition.
Is stored municipal water safe to drink? +
Storage alone does not guarantee drinking-water safety. Use a tank and fittings suitable for potable water, protect openings from contamination and follow a cleaning and inspection plan. Water turnover helps, but does not replace maintenance. If contamination is suspected, use a known safe drinking-water source until the problem has been assessed.
Can my inverter run the pressure pump? +
Possibly, but the inverter must handle the pump’s starting demand as well as its running load alongside other connected appliances. Battery capacity determines operating time. Have compatibility checked before choosing the pump; do not assume that an inverter powering lights can also start it.
Can I connect rainwater to the same household supply? +
Do not connect untreated rainwater directly into potable plumbing. Rainwater needs a separate, properly designed arrangement with appropriate separation, labelling and treatment for its intended use. Discuss the water source before selecting tanks, pumps or filters.
