Step 4: Bending the copper tubing
I used a tubing bender to safely bend my copper without any kinks. Don't be like me and underestimate how much copper tubing you will need. I ran out and had to get more and use a coupling to continue. I wound up needing almost 18 feet. Buy the right amount the first time and you won't need to worry about it.
To keep my coils relatively equal, I used a 3 liter plastic soda bottle to check my progress.
The coil itself begins straight so it can go to the ball valve. I turned it about 90 degrees to begin the coils. I made about 9 coils and then did another 90 degree bend straight up.
It's difficult to describe just how I shaped the pipe. If this step's description doesn't make sense, continue anyway and see how it will function.
