following operating specifications. Failure

If the hardness of your water is above 10 gpg (171 mg/L), lime scale will build
up rapidly on the membrane inside of the RO membrane cartridge. Scale
buildup will plug the RO membrane cartridge and make the system ineffective.
We do not recommend the PB5RO to be used with water in excess of 10 gpg
(171 mg/L) hardness, unless the water is softened prior to the reverse osmosis
system.

See your local dealer or water treatment specialist to reduce these substances
in your water.
