Under Counter Water Filters
are installed out of sight below a preparation bowl in the kicthen area or in a cupboard and are plumbed into the feed water line or pipe. Normally feed water pipes are either poly cop , copper or galvanised.
Under counter water filters are available in 2 stage, 3 stage , 4 stage and Reverse osmosis units . NB ** For any system that is plumbed in it is important that the water pressure is not higher than 3 bars of pressure for the filters of a maximum of 5 bars for a Reverse Osmosis system .
3 Stage Under counter water filter
A higher pressure than this may cause the systems to leak profusely and it is highly recommended that an inline pressure reducer be fitted if the pressure is above 5 bars. These units are fitted between the feed water valve and the filter unit.
5 Stage Reverse Osmosis System w/booster
Fittings are supplied that either have to be connected directly to the pipe work and require some plumbing experience such as the 1/4 ” or 3/8 ” chromed Eezee Connectors below . Once these are connected feed water supply to the filters can be isolated by the ball valve attached .

Inline Pressure reducers can be attached between the feed water ball valve and the system itself.

A typical installation diagram for undercounter water filters looks like the diagram below. Note that these filters come with their own taps .
How to Install an Under Counter Filter
To install a 5 stage revrse Osmosis system takes access to a 3rd outlet and that is the drain. Reverse Osmosis systems purify water and in doing so provision is made to self flush the membrane that accomplishes this process and that is where the water wastage comes in . Some systems waste 2 to 3 times the amount of water that they purify.
