Common water concerns we address
These are the everyday issues that lead households in Pretoria and across Gauteng to ask about under-counter reverse osmosis systems.
Concerns about dissolved contaminants
Fine dissolved substances that pass through basic carbon filters can remain in drinking water, and some households want a finer level of reduction.
No space for a whole-home system
Not every kitchen can fit a point-of-entry install. An under-counter unit keeps the treatment out of sight and the worktop clear.
A dedicated drinking-water tap
Many households want one clearly separate source of drinking water rather than treating every tap in the home.
What to expect
A practical, professional process that keeps the system matched to your water and your needs.
- 01
Check your supply and space
We look at your incoming water and the space under your sink so the unit fits and is matched to what your supply actually needs.
- 02
Specify the right stages
We choose the pre-filtration, membrane, and polishing stages suited to your water rather than a fixed off-the-shelf package.
- 03
Install under the counter
We fit the system neatly beneath the sink and connect a dedicated drinking-water tap, holding the work to our workmanship guarantee.
- 04
Maintain over time
We help you keep to the right service intervals for filters and the membrane so the water quality holds.
Ways we can set this up
We specify the right approach for your supply rather than selling a fixed package. These are the common configurations we install.
Compact under-counter RO
A reverse osmosis system that fits beneath the sink and feeds a dedicated drinking-water faucet.
Best for: Households that want high-quality drinking water without a whole-home install.
Multi-stage pre-treatment
Sediment and carbon pre-filtration staged to protect the membrane and suit your supply.
Best for: Supplies with sediment or chlorine that would otherwise shorten membrane life.
Dedicated drinking tap
A separate faucet at the sink so treated drinking water is clearly distinct from the rest of the home.
Best for: Kitchens where the main goal is better drinking water.
How an under-counter RO system works
A compact reverse osmosis system treats water in stages before it reaches your glass. This is the general flow, from incoming supply to the drinking tap.
- 1
Pre-filtration
Sediment and carbon pre-filters protect the membrane by catching particles and reducing chlorine before the water reaches it.
- 2
Reverse osmosis membrane
The fine membrane reduces a wide range of dissolved substances that basic carbon filtration leaves behind.
- 3
Polishing and storage
A final carbon polish improves taste, and a small storage tank keeps drinking water ready at the tap.
Product warranty
12-month warranty on all products
Workmanship
2-year workmanship guarantee

Under-counter Reverse Osmosis Systems questions
The questions households ask most about this service. For broader water-quality questions, see our full FAQ.
- Is an under-counter RO system the same as a whole-home system?
- No. An under-counter reverse osmosis system treats water at one point of use, the drinking tap, rather than every tap in the home. It is a focused choice for households whose main goal is better drinking water.
- Does reverse osmosis waste a lot of water?
- Reverse osmosis works by separating the treated water from the water that carries away the rejected substances, so some water is used in the process. We explain how the unit we specify behaves during the assessment so you know what to expect.
- How often does an under-counter RO system need service?
- Pre-filters generally need replacement every few months and the membrane on a longer interval, depending on your water and usage. We help you keep to the right service intervals so the water quality holds.
