How do you connect a new water line to an existing line?
The most common way to connect a new drain, vent, or supply line to an existing line is to install a tee fitting. To do so, shut off water to existing supply pipes and drain the lines. Flush all toilets and caution others not to use drains. After opening a drain line, make sure no one uses a sink or faucet that drains into it.

Typically, an entire bathroom group vents in the wall behind the sink, where a 1 1/2- to 2-inch vent pipe connects to a sanitary T-fitting. The vent pipe runs upward to meet the house’s main vent-and-soil stack in the attic. The sink’s drainpipe runs downward to connect in the floor to the main drainpipe, which originates with the commode.
