Backup water for Gauteng

Taps off.
FlowSa on.

Tanks, filtration and a battery that keeps your pump running when the grid drops. Installed, tested and ready before the next outage.

One system, four parts that work together.

When municipal water stops, your home switches to the tank on its own. When the power goes, the battery keeps the pump pushing pressure to every tap.

  1. 01

    Tank

    Holds your reserve. It fills from the municipal line while water is on, so it’s full when the supply stops.

    Filtration

    Three stages take out sediment, chlorine taste and fine particles before water reaches your taps.

    Pump and battery

    A pressure pump with its own lithium battery. Load shedding doesn’t take your water pressure with it.

    Your taps

    Showers, kitchen, toilets and geyser. The switch-over is automatic, so you hear about outages on the news, not in the shower.

Common questions

How big a tank do I need?

A typical person uses about 150 litres a day. A family of four with a 5 000 L tank has roughly eight days of normal use, and much longer if you cut back during an outage. The slider above does the maths for you.

Does the tank fill itself?

Yes. The tank is connected to your municipal supply and tops itself up whenever water is on. When the supply stops, your home draws from the tank automatically.

What happens during load shedding?

The pressure pump runs off its own lithium battery, so you keep normal water pressure at every tap. The battery recharges when the power comes back.

Can we drink the tank water?

Our three-stage filtration makes water clean and clear for household use. For drinking water we recommend adding a UV steriliser, which is included in the Full Flow package.

Never run dry, Gauteng.
