We just got a new Refrigerator and it has an ice maker. The plumber that came to install it used plastic tubing to hook up the ice maker instead of the copper tubing that Sears sold me and that they told me he would use. The plumber said that plastic was better and that it wasn't necessary to use the copper tubing kit that Sears sold me. Is he right or should I have insisted he use copper? The plumber didn't charge me anything extra for the tubing. He said it was included in the installation price and that I should take the copper kit back to Sears and get my money back. ( When I bought the refrigerator, Sears sold me the copper kit for $32.00 and said I would need it when the installer came) Thanks.

There is nothing wrong with using the plastic pipe, as there is little pressure going through it for the saddle were they taped into the copper from. Although I like to use the copper myself, there is nothing wrong with that kind of tubing being used.

While the plastic should be fine, in fact it be under the full pressure of the other lines in the house except when water is flowing to the ice maker.

Sears is in the business of selling stuff. Yes, you would have needed it if the other was not available. Enjoy the money back, maybe use it to buy some drinks to put your new ice cubes in!

Oops, I was thinking of a pressure reducing saddle, But you it will still work fine

Yep, the pressure in the small line is just like the rest of the house, around 40-45 psi. Plastic is fine for this application.
