Water Filters Johannesburg
Water filtration for Johannesburg properties that rely on storage tanks and backup supplies, with scale control for harder Gauteng water.
How we work in Johannesburg
Johannesburg's municipal water comes from Rand Water and is treated to drinking standard, but frequent supply interruptions mean many homes and businesses rely on storage tanks and backup supplies. Water that has sat in a tank, or comes back through the pipes after an outage, often brings sediment and discolouration with it.
Gauteng water is also harder than most coastal supplies, so scale on geysers, kettles and coffee machines is a common complaint. We usually pair sediment and carbon filtration with softening or scale control where a hardness test shows it is worth treating.
What the specification covers
Outages and hard water shape most Johannesburg systems.
Tank water
Stored water is filtered on its way out of the tank, not just at the mains.
After an outage
Sediment stirred up when pipes refill is caught before it reaches taps and appliances.
Scale control
Softening is sized to measured hardness and household use.
FAQs
Questions before we quote
Why is my water brown after a water outage?
When pipes refill, sediment and rust that settled during the outage are disturbed. A sediment filter where the water enters the property catches most of it before it reaches taps, geysers and appliances.
Should I filter water from a storage tank?
Yes. Tanks collect sediment and can warm up, so a sediment and carbon stage after the tank, plus UV if the water is used for drinking, keeps it consistent.
Do I need a water softener in Johannesburg?
Not always. A hardness test tells us whether scale is worth treating at your property, and we only recommend a softener when the numbers support it.
