(1): Usually Swiss homes are equipped with pressure regulators adjusted to 4 bar.

(2): Switzerland Drinking water contains between 150 and 350 mg / l of dissolved solids and there is no drinking water with more than 1000 mg / l of dissolved solids (WHO recommendations: max. 500 mg / l). If you have any doubt, send us or bring us a sample of your water to a free control of the concentration of dissolved solids.

(3) If your water has a hardness greater than 17 ° dF, there must be a water softener or a electronic anti-scale system (up to about 25 ° dF) before the reverse osmosis unit. Contact us for a special offer.

(4): In Switzerland the concentration of chlorine in drinking water is generally less than 0.2 mg / l

(5): Normally drinking water contains no or very little dissolved iron and manganese. If your water should be an exception, contact us for an offer.


The installation should be done by your plumber of trust.
