Step 1: Cut Into the Water Lines

To start the tap-ins, start with the water lines. Using a pipe cutter, cut into the hot and cold water lines. Make sure to have a bucket handy for any water left in the lines

Step 2: Cut the Pipe

Use the copper 'T' fitting as a template to mark the space where the water line will be cut out. Using a mini-cutter, remove this section of pipe.

Step 3: Install the 'T'

Clean and flux the pipe and fittings and install the 'T'. Finish by running your water lines to the bar area using basic soldering techniques.

Step 4: Stub the Pipes

Stub the pipes through the wall and you're ready to hook up the fixtures. To do this, use a 5/8 drill bit to drill a hole at the base of the cold water copper line. Then, slip on a copper 90 and a short copper piece through the hole. Solder all joints.

Step 5: Attach Double Stops

Step 6: Do the Rough-In Procedure

It's time to do the drainage tap in – this whole process is called a rough-in procedure. No two plumbing systems are alike so you may tap in a different way.

Step 7: Drill Holes in the Water Line

To make a template for the tap-in, drill holes on the top and bottom side of the water line. Then, drill two more holes next to the closest stud.

Step 9: Drill Into the Water Line

Drill into the water line using a two inch hole saw, then install the saddle 'T'.
