Frequently asked questions
Here are some common questions about Reverse Osmosis.
A reverse osmosis (RO) system is one of the most effective ways to purify drinking water. It uses water pressure to force water through a semi-permeable membrane that removes up to 99.9% of common contaminants. Renewell Water reverse osmosis systems also include additional filtration stages that improve the taste, smell, and overall quality of your drinking water, delivering fresh, filtered water directly from a dedicated kitchen tap.
Renewell Water under-sink filtration systems are installed beneath your kitchen sink and connect directly to your water supply. Depending on the model, they use activated carbon filters, reverse osmosis membranes, or a combination of both to reduce impurities, improve taste, and provide cleaner, healthier drinking water whenever you need it.
The contaminants removed depend on the type of filtration system you choose. Renewell Water offers systems that reduce chlorine, sediment, heavy metals such as lead and copper, pesticides, bacteria, viruses, and other common contaminants that affect water quality and taste. Our team can recommend the most suitable solution based on your water supply and household requirements.
Renewell Water reverse osmosis systems are highly effective at removing dissolved minerals, heavy metals, chemicals, and other unwanted substances from drinking water. These include lead, arsenic, mercury, fluoride, chlorine, chromium, copper, nitrates, sulphates, aluminium, barium, selenium, zinc, and many more.
They also reduce microplastics, total dissolved solids (TDS), sediment, turbidity, unpleasant tastes and odours, and colour-causing compounds.
While some systems are suitable for DIY installation, Renewell Water recommends professional installation to ensure the system is fitted correctly, all connections are leak-free, and the unit performs at its best from day one.
Yes. In fact, Renewell Water often recommends combining both systems. A water softener protects your plumbing and appliances by reducing limescale, while a reverse osmosis system provides purified drinking water. Together, they deliver better water quality throughout your home.
