Sub-Zero with Reverse Osmosis Water System

Topics:

  • Can the water supply for a Sub-Zero unit come from a reverse osmosis (RO) system?
  • Can Sub-Zero with an internal water filter be connected to a reverse osmosis system?
  • Are there any concerns when using a reverse osmosis system?

Answer:

A reverse osmosis (RO) system may be used with Sub-Zero products.

  • It is acceptable to connect a non-water filter model to a reverse osmosis system as long as the water pressure stays steady and is adequate between 35 - 120 psi.
  • This makes sure that the ice maker will operate properly.
  • Consider adding a pressure booster or regulator if water pressure is inconsistent or too low.
  • Contact the reverse osmosis provider or speak with a plumber for suggestions on boosters.
  • Do not use copper after the reverse osmosis system, as this can cause leaching. Check with your reverse osmosis provider.
  • For Sub-Zero models with an internal water filter installed, such as a push-in or twist-in filter, it is advised to bypass this internal filter when connecting the product to a reverse osmosis system.
