Using Copper Tees allows connections at each end and allows use of solder less than silver solder such as 95-5.

Copper Tees are preferable where two line ends have not yet been attached or where it is desirable to cut a line rather than drive a hole in an uncharged system. Copper Tees can save time and money.
