I need to supply water to a new addition by tapping into an exterior faucet line which is about 6 ft. from the new addition. The homeowner doesn’t want to disrupt the interior room as it is finished. This leaves me with the chore of accessing the pipe from the exterior and running the new pipe inside the exterior wall for that 6 ft.. I live in New England – any mechanical or insulating sugestions?

This isn't an answer directly to your question, but a concern you should address. By "exterior faucet line" do you mean an outdoor hose bibb? If that faucet line is 1/2" pipe, you probably can't run any more than one additional faucet off it (not a shower) and still meet code. And if you do "sneak it by", your customer will forever be short of a good supply of water in that addition. What fixtures do you have in the new addition that require a water supply? Does the new addition have a bathroom with a shower in it? Undersized piping has "wide water temperature fluctuations" and "liability" written all over it.
*See the thread "avoiding frozen pipes." Now dealing with this with existing installation. I'd avoid installation in an exterior wall by hook or by crook. The owner isn't going to be very happy about the water damage to that nice finished interior if the line bursts.This happens here in extreme SW NE near the water. Most of the rest of NE is even colder.On a previous house I moved the supplies out of exterior walls after some number of repairs and was able to hide them inside cabinetry and some covers disguised as decorative millwork.I'd guess the easiest part of the problem is replacing the 1/2 feed to hosebib with 3/4.Scott.
