The instruction doesn't explain if I need to install the adapter against wall or away from it.
The picture shows some slack between the wall and the adapter, but it doesn't explain how far either.
And also how long the copper pipe should be from the wall?
Thank you for your question. When sweating on Delta Faucet model # RP61269, you will cut the tubing 2"-4" from the finished wall. After brazing, the adapter will be 1/4"-1/2" from the finished wall.
When brazing on the adapter, remove the external o-ring first and cool the brass down prior to re-installing the o-ring. If desired, tubing may be cut off just beyond or flush with the end of the adapter.
