What is the recommended connection method for refrigerators using ice makers?

The recommended connection method for refrigerators using ice makers is to tee off the faucet line. This method allows for a straightforward and efficient water supply to the ice maker while maintaining access to the faucet for normal use. By teeing off the line, you can create a split in the plumbing that directs water both to the tap and to the refrigerator, ensuring that the ice maker receives the water it needs without requiring a complete rerouting of the home's plumbing system.

Connecting directly to the main supply can be less practical and may involve significant plumbing modifications that aren't necessary. Using a separate water tank tends to complicate the system and introduces additional maintenance needs, which may not be suitable for many households. Installing a filter after the ice maker is beneficial for improving water quality, but it does not address how the water supply is initially connected to the refrigerator; thus, it doesn't serve as a method of connection. Tapping into the faucet line is the most effective solution for ensuring a reliable water source for the ice maker.
