Water Filter Supplier in Johannesburg
Whole-house systems, kitchen under-sink filters, fridge water filters and reverse osmosis. Andy Plumbers supplies and installs the full range of residential water filtration across Sandton, Bryanston, Fourways, Randburg and the surrounding suburbs. Decades of trusted local water work, one team, one quote.
Most Joburg homes don't need a brochure to know there's a water problem. You can taste it in the kettle, see it on the shower screen, smell it after a council pipe job nearby. We've spent decades quietly solving this for families in Sandton cluster homes, Fairland gardens, Northcliff face-bricks, Bryanston townhouses and Parkhurst cottages. Whether it's a single fridge filter swap or a full whole-house installation with a softener and a dedicated drinking line, we handle it under one team and one quote, with no upselling and no surprise fees.

Why Joburg Homes Need Proper Water Filtration
The water that leaves Rand Water's treatment plants is genuinely good. The water that arrives at your kitchen tap has spent hours travelling through a network of ageing supply pipes, pressure boosters, reservoirs and your own internal plumbing, picking things up along the way. By the time it lands in your glass, it usually carries some combination of chlorine taste, fine sediment, dissolved iron and copper from older pipework, and hardness minerals that scale up your kettle, geyser element and shower screen.
None of this is dangerous in the short term. All of it makes your water taste flat, your kettle die early, your shower screens look permanently smeared, and your morning coffee taste like the inside of a hosepipe. Filtration solves it without you ever having to think about it again.
What we typically see in Joburg suburbs
- Sandton, Bryanston, Hyde Park: high pressure, occasional discolouration during council main repairs, scale buildup from hard water mixing zones
- Fourways, Dainfern (older estates): longer reticulation runs from the reservoir, more sediment, intermittent pressure dips
- Randburg, Fairland, Northcliff: mature suburbs with original galvanised feed lines still in some homes, metallic notes and rust flecks after a supply interruption
- Parkhurst, Linden, Greenside: 1930s heritage cottages with original lead-jointed runs in places, very occasional sediment after main breaks
- Rosebank, Killarney apartments: rooftop tank supply, warm-weather algae and biofilm risk if tanks aren't maintained
Every one of these is a different filtration brief. We don't sell a one-size-fits-all package, because there isn't one.
The Four Types of Water Filtration We Supply
1. Fridge Water Filters
The smallest filter in the home, but the one most owners forget about until the indicator light goes red. Side-by-side and French door fridges from Samsung, LG, Bosch, Whirlpool and Smeg all need their water filter replaced roughly every six months. Skip a year or two and you'll start tasting it before you see it.
We supply genuine-compatible cartridges for the major models, swap them out, flush the line, and reset the indicator on your panel. If you don't know your fridge model, send us a photo on WhatsApp and we'll work it out. Dedicated guides: Samsung fridge filters, LG fridge filters, or use the filter finder tool.
2. Kitchen Under-Sink Filtration
The default upgrade for any family that wants properly filtered drinking water without committing to a whole-house system. A 3-stage cartridge bank lives quietly inside the kitchen cabinet, fed from the cold supply, with a dedicated chrome tap on the counter for drinking and cooking water. Cartridges last 6 to 12 months depending on the household, and we handle the replacements when they're due.
This is the right system for renters, smaller homes, or anyone who only wants filtration where it matters most. We can quote a basic 3-stage carbon and sediment unit, or step it up to a reverse osmosis system for premium drinking-water purity. Read more about under-sink installation.
3. Whole-House Filtration
The gold-standard for a home that's planning to stay in one place. Filtration is plumbed in at the main water inlet, so every tap, every shower, every toilet cistern and every appliance gets clean water. This is what protects your geyser element, your washing machine pump, your dishwasher and your kettle from premature death by scale.
Whole-house systems range from a simple 2-stage sediment-and-carbon arrangement up to a multi-stage installation with a water softener, KDF media, UV sterilisation and a downstream RO drinking line. We size the housing to your home's actual peak flow so pressure stays exactly where it should.
4. Reverse Osmosis (RO) and Water Softeners
For households that want bottled-water-quality drinking water from the tap, a small under-sink reverse osmosis unit is the answer. RO strips dissolved solids down to single-digit parts per million, removing fluoride, nitrates, heavy metal traces and the residual taste even good carbon filtration leaves behind. Output goes to a small storage tank and a dedicated tap.
Water softeners are a different problem solver. If you're tired of scale on your shower screens, white spots on glassware and short geyser life, an ion-exchange softener is what you actually need. We pair softeners with whole-house filtration where it makes sense, and we'll be honest about when it doesn't.

Why Homeowners Choose Andy Plumbers for Water Filtration
One team for the whole job
Most water filter sellers in Joburg are pure retailers. They'll ship you a box, then you spend a weekend chasing a plumber to actually install it. We do both, under one roof, with one quote and one accountable team. If something needs adjusting in week three, the same person who installed it answers the WhatsApp.
Plumbers first, retailers second
We've been a working maintenance plumbing business for decades. The water filter side grew out of that, not the other way around. So we approach a filter install as a plumbing job that needs to last 10+ years, not a product sale. The fittings are the right grade, the bypass valves are properly placed, and the housing isn't held up by hope and a wall plug.
Honest sizing, honest options
If you don't need a whole-house system, we'll tell you. If a 3-stage under-sink unit will solve 90% of your problem for a fraction of the cost, that's what we'll quote. Our reputation in the suburb is worth more than an upsell, and we've earned it the long way.
Ongoing cartridge support
The most expensive water filter is one that nobody changes. We track the systems we've installed and reach out via WhatsApp when your cartridges are due, so you never end up with a system that's quietly running on a six-year-old filter.

We supply and install the full range of residential water filtration solutions: whole-house systems that filter every tap in the home, kitchen under-sink filters with a dedicated drinking water tap, fridge water filter replacements for Samsung, LG, Bosch, Whirlpool and Smeg fridges, reverse osmosis systems for premium drinking water, water softeners for hard water, and dedicated borehole filtration setups.
We can also test your water before recommending a system, so you only pay for the filtration you actually need.
We service Sandton, Bryanston, Fourways, Hyde Park, Morningside, Rosebank, Randburg, Fairland, Northcliff, Linden, Parkhurst, Greenside, Cresta and the surrounding northern Johannesburg suburbs from our Fairland base.
We're a short drive from most of the area, so we usually book installations same-week and respond to enquiries the same day during business hours.
Pricing depends on the type of system, your water quality, the layout of your home and the brand of fridge or fixture involved. We give every customer a straight, written quote after a quick conversation about what you need.
Send us your address or your fridge model number on WhatsApp or via the enquiry form and we'll come back the same day with a clear quote, no pressure to commit on the spot.
Joburg's municipal water leaves the treatment plant in good shape, but the journey through ageing pipework picks up sediment, chlorine taste, occasional discolouration and the odd metallic note. If your water tastes or smells off, leaves white scale on kettles and shower screens, or you simply want better drinking water for the family, a properly chosen filter solves it.
We test the water before recommending anything so you don't over-spec a system you don't need.
Yes. We carry replacement cartridges for the systems we install, plus the most common fridge filter models for Samsung, LG, Bosch, Whirlpool and other major brands.
If you have an existing system from another installer, send us a photo or the cartridge model number on WhatsApp and we'll source the right replacement and bring it out.
A fridge filter swap is usually 20 to 30 minutes including the indicator reset and a flush. A kitchen under-sink system is a 2 to 3 hour install. A whole-house system depends on access and pipework but typically takes half a day.
We confirm the realistic timing in your quote so there are no surprises on the day.
A correctly sized system will be unnoticeable in day-to-day use. Most pressure complaints we attend stem from undersized filter housings or restricted feed plumbing installed by a previous contractor.
We size the housing and inlet to your home's actual flow demand, not a generic spec sheet.
Yes. We work with managing agents, estate maintenance teams and Airbnb hosts on rolling filter replacement and installation programmes.
Get in touch through the enquiry form and we'll set up a single point of contact for the portfolio.
