I just bought a new fridge to replace the older model that is having problems. The new one has an icemaker, the old did not. There is a copper pipe sticking out about 2-3 inches from behind the old fridge. The line is capped off. I would like for the fridge (since it is a bit larger) to be able to sit further back. Is it a big deal to turn off the water, cut some of this pipe out, cap it until the fridge is delivered (somehow... compression bolt??) and then have them install the icemaker? Are there any specifications about how far the pipe must extend from the wall. I doubt it but wonder why they let it stick out so. Also, since I don't think it has ever been used, will it be safe to begin using it now, after 19 years? Thanks for any tips.
