A:Answer We bought a LG LRDCS2603S and best buy insisted their smart choice stainless steel waterline kit be installed. After several days and a lot of ice, the ice still had that chemical taste. After talking to LG customer support and reading the owners manual carefully, the manufacturer recommends using copper or PEX tubing. I contacted geek squad, they returned and installed the PEX tubing kit and just like that, the ice tasted good. They no longer carry the PEX waterline kit. Go figure
