Sub-Zero Water Line and Valve Specifications
- What type of material should the water supply line be made of?
- Should the water supply line be copper, braided stainless steel, PEX tubing, or another type of material?
- Can a self piercing-water valve be used?
- Should the unit be plumbed to hot or cold water?
- Will hooking the unit up to hot water cause damage?
Water supply lines to a Sub-Zero should be 1/4" OD copper, braided stainless steel, or PEX tubing material.
- The water supply line should be connected to the house supply with an easily accessible shut-off valve.
- Water supply lines are provided by and installed by a local plumber. Sub-Zero does not carry home water supply lines.
- Use a saddle valve, do not use a self-piercing valve.
- Installation must comply with all applicable plumbing codes.
- Sub-Zero recommends connecting the unit to cold water. Cold water supply will make ice faster and dispense colder water.
- It is not suggested to use a flushing valve to periodically flush the water line due to low water supply.
- Consult a plumber for home water supply connection installation and any issues that are related to the home water supply. See Blue or Green Ice Cubes or White Flecks in Ice.
