New construction is typically 3/4". Old services can be as small as 1/2". The biggest that I have ever heard of is 2"

What is the typical material ?

What did it look like???

Nowadays, copper. Plastic if it is a private well. Older houses, lead, glavanized, or maybe even brass.

Hope this helps

In my area the typical material is Copper. I do find Lead at times and also CVPC. 90% of the time I’ll find Copper.

The typical size is 3/4". I do find 1/2" at times but it’s noted in my report as…

*1/2” piping exists at main supply. Today’s standards require 3/4”, improving water flow.

Here a 25 year old house would have a 3/4" service, today new construction requires a 1"
