Reverse Osmosis System Installation in Randburg

The highest level of water purification you can have at home. Reverse osmosis removes up to 99% of contaminants — bacteria, chemicals, heavy metals, and dissolved solids. Professional RO installation across Randburg, Fairland & Northcliff.

"We spent R200 a month on bottled water. The RO system paid for itself within a year."

A Parkhurst family of four was buying cases of bottled water every week. They did not trust the tap water — Joburg's water quality had been in the news too many times. They contacted us about a water filter but were not sure which type.

We tested their tap water first. Results showed the municipal water was actually safe to SANS 241 standards, but it had elevated chlorine levels and total dissolved solids that gave it an unpleasant taste.

An under-sink reverse osmosis system was the perfect solution — it removed 99% of everything, leaving them with water that tasted better than any bottle they had ever bought. The RO unit sits neatly under the kitchen sink with a dedicated faucet on the counter.

Total cost was less than one year of bottled water. No more plastic waste, no more heavy bottles from the shop.

RO Systems for Every Need

From a single drinking water faucet to whole-house purification, we install the right reverse osmosis system for your home or business. Every installation starts with a water test so we know exactly what the system needs to handle.

Under-Sink RO Systems

The most popular choice for Randburg homes. A compact reverse osmosis unit sits under your kitchen sink and provides purified drinking and cooking water through a dedicated faucet. Five to seven stages of filtration remove virtually everything from the water.

  • 5-7 stage purification
  • Dedicated drinking water faucet
  • Pressurised storage tank
  • Removes bacteria, chemicals, heavy metals
  • Annual filter replacement service

Whole-House RO Systems

For homes that want RO-quality water from every tap — particularly useful for borehole-fed properties where the entire water supply needs purification. These are larger systems with higher flow rates, designed for whole-household demand.

  • All-tap RO purification
  • High-flow membrane technology
  • Pre-filtration included
  • Borehole water compatible
  • Automatic flush cycles

Commercial & Light Industrial RO

Restaurants, offices, clinics, and food preparation businesses in Randburg that need consistently purified water. We size commercial systems to handle higher volumes with minimal maintenance and consistent output.

  • Higher volume capacity
  • Multiple membrane configuration
  • Water quality monitoring
  • Consistent output pressure
  • Maintenance contracts available

How We Install Your RO System

Every installation starts with a water test and ends with purified water from your tap. Most under-sink installations are completed in a single visit.

1

Water Testing

We test your water to determine what the RO system needs to handle. Municipal water, borehole water, and tank water each have different contaminant profiles. The test results determine the correct pre-filtration stages and membrane specification.

2

System Design & Quote

We recommend the right RO system for your needs — under-sink for drinking water, whole-house for total coverage. You get an itemised quote covering the unit, storage tank, faucet (if applicable), pre-filters, pipework, and installation. No hidden costs.

3

Installation & Setup

We install the system, connect the water supply and drain, mount the faucet, set up the storage tank, and run the system through its initial flush cycle. You get purified water from the first glass. We explain the maintenance schedule and when filters need replacing.

Why Reverse Osmosis From Andy Plumbers

RO is the gold standard for home water purification. Here is why our approach delivers the best results for your home and your water.

The Highest Level of Home Purification

Reverse osmosis removes up to 99% of dissolved contaminants including bacteria, viruses, chlorine, fluoride, lead, arsenic, nitrates, and total dissolved solids. No other home filtration technology matches RO for pure water. If you want the cleanest possible drinking water, this is it.

Test First, Then Treat

We test your water before recommending RO. Sometimes a simpler carbon filter is enough. Sometimes RO is the only option that will handle what is in your water. Honest advice based on your actual water quality, not a sales pitch.

Plumber-Installed for Reliability

An RO system needs proper water supply connections, drain connections for the reject water, correct pressure, and sometimes a booster pump. We handle all the plumbing — and if your system needs to integrate with a borehole or water backup, we do that too.

Long-Term Cost Savings

An average family of four spending R200 per month on bottled water spends R2,400 per year. An under-sink RO system costs R5,000 to R12,000 installed and annual filter replacements cost R500 to R1,000. The system typically pays for itself within 18 months — and produces less plastic waste.

Reverse Osmosis in Randburg and Surrounding Suburbs

Reverse osmosis is growing in popularity across Randburg, driven by concerns about Johannesburg's water quality and the increasing use of borehole water. In Fairland and Northcliff, many homeowners who have installed boreholes pair them with RO systems for drinking water, while using the basic filtered borehole water for showering, laundry, and garden.

Parkhurst and Linden residents often choose under-sink RO simply for the superior taste — once you drink RO water, municipal tap water tastes noticeably different.

We also install standard water filters and under-sink units for homes that do not need full RO purification. The right system depends on your water test results, your budget, and how you use water. We always recommend testing first.

We serve Fairland, Northcliff, Parkhurst, Linden, Blairgowrie, Bordeaux, Greenside, and Ferndale.

Common Questions About Reverse Osmosis

What is reverse osmosis and how does it work?

Reverse osmosis forces water through a semi-permeable membrane with pores small enough to block virtually all dissolved contaminants. The clean water passes through; the contaminants are flushed away with a small amount of reject water. Most home RO systems also include sediment pre-filters and activated carbon post-filters for additional treatment stages.

Does an RO system waste water?

Yes, RO systems produce some reject water — typically 2 to 3 litres of reject for every litre of purified water in standard residential units. Higher-efficiency systems reduce this ratio. The reject water is not harmful — it simply contains the concentrated contaminants removed from your drinking water. Many homeowners route the reject water to their garden.

How much does an RO system cost to install in Randburg?

Under-sink RO systems range from R5,000 to R12,000 fully installed, depending on the number of stages and the brand. Whole-house RO systems for borehole-fed homes start from R15,000 and can go higher based on capacity and pre-treatment requirements. We provide detailed quotes after assessing your water quality and home layout.

How often do RO filters need replacing?

Pre-filters (sediment and carbon) need replacing every 6 to 12 months. The RO membrane itself typically lasts 2 to 3 years depending on water quality and usage. The post-carbon filter is replaced annually. We can set up a maintenance schedule and handle all replacements for you.

Is reverse osmosis necessary if I am on municipal water?

It depends on your priorities. Municipal water in Randburg is generally safe to SANS 241 standards. But if you want to remove chlorine taste, fluoride, dissolved solids, and trace chemicals that basic filtration does not catch, RO is the answer. Many Randburg homeowners install RO purely for taste improvement. If you are on borehole water, RO may be essential depending on your test results.

The Purest Drinking Water in Your Home

Stop buying bottled water. A reverse osmosis system gives you water that is cleaner than any bottle, right from your kitchen tap.
