Cleanwater Existing Tap Undersink Water Filter Kit 15mm Push Fit

The Cleanwater Existing Tap Water Filter System is an ideal water filter system for installing under the kitchen sink. The system has no need for a separate tap as it will filter all the water coming from your existing kitchen tap. This is because this system uses 15mm push fittings for the inlet and outlet. This means your 15 mm copper or plastic pipe can simply be pushed into the unit and released with ease.

The Cleanwater Existing Tap system therefore makes a perfect solution for an easy installation as it can be fitted in less than 15 minutes. The system is perfect if you have a solid kitchen worktop (marble, granite, stone, wood etc.) and do not want to have a separate tap in place. There is an option to have this exact system with a separate tap and fitting kit if you would prefer to have this option, as many people which children or very elderly persons do often prefer a separate tap.

There are two filters in the system, which both serve a different purpose with the ultimate result being purified, clean, healthy and great tasting water for all your drinking, cooking, washing and cleaning needs.

Filter 2: Cleanwater No Scale GAC, Phosphate & De-Alk Resin Cartridge –  changed every 3-6 months (dependent on hardness)

✔ Granular Activated Carbon (GAC) – for chlorine, taste and odour reduction

✔ Phosphate – for scale inhibition

✔ De-alk resin – for temporary hardness and heavy metal reduction

The Cleanwater No Scale 2.5 x 10 GAC/Phosphate & De-Alk Filter incorporates granular activated carbon (GAC) which is combined with Phosphate and De-alk resin. The filter is effective against chlorine, taste and odour, heavy metals e.g. lead, and will also tackle hard water, which is seen as limescale in kettles and as an unsightly scum on the surface of hot drinks. Water hardness varies greatly depending upon location, so the filter will need to be replaced at 3 – 6 monthly intervals or longer all of which entirely depends on the hardness of your water and the amount you use.
