I am looking to install an automatic shut off valve on my main water line. Looking at it I am not so sure it is 3/4 inches. The house was built in the 1950's. I was going to use the pro-line push-fittings.
Before I cut the pipe I'd like to make sure I can finish the install. It's certainly larger than a 1/2 inch pipe. It just does not look at big as newer 3/4 inch pipes I have installed elsewhere
Is there a chance that this pipe could be slightly smaller, was there a difference in pipe thicknesses back in the day?
Thanks,
Chris

What material is the pipe? Copper or galvanized steel?

Copper under all the dirt I sanded off
I did a few more comparisons and it has the same circumference as the newer 3/4 inch pipes I installed so perhaps it's just me.
Just wanted to make absolutely certain.
