If you are replacing or adding new pipes, there are a few things to consider before deciding which type of copper and pipe to use.

Start by considering the function of the pipes and what devices they need to be connected to. Figure your appliance fixture unit in your local building code. A fixture unit is a rating that determines how much water you need to supply, which will determine the size of the pipe needed.

The nominal pipe size of copper pipe is always 1/8 inch less than the actual outside diameter. If for some reason, the pipe size is not written on the pipe, you can use the string method to find it.

Follow the below steps to measure copper pipe by string method.

1. Find the circumference of the pipe by wrapping the string around the pipe once. Mark the section of the string where it begins to overlap.
2. Measure the length of the string wrapped around the pipe with a ruler.
3. Divide the length by 3.143, and this is the outside diameter of your pipe.
4. To find the NPS, you simply subtract 1/8 inch (or 0.125 inches) from the outside diameter of the pipe.
