PI® Anti-lime prefilter
Is the lime load exceptionally high (higher degree of water hardness) or the mains water values vary too much, the PI® anti-lime prefilter should be used. This way the membranes and the pump are protected and their lifespan will be extended.
Recommendation: Install the anti-lime prefilter if the mains water hardness exceeds 20°gh / 35,6°fh.
Installation of the PI® anti-lime prefilter
The PI® anti-lime prefilter must be installed prior to the reverse osmosis. You can find the exact information about the PI® anti-lime prefilter’s installation in our guide.
