Are alpex installations possible with softened water?

Yes, alpex installations (pipe + PPSU + brass) can be operated with softened water of up to 0°dH. The limit value for sodium ions of 200 mg/l may not be exceeded during softening. For reasons of corrosion protection, it is recommend that the water hardness level should be of at least 3°dH. If drinking water is intended for human consumption, water hardness of 4 to 8°dH is ideal.
