Since I don’t know where else to put this I’ll start here.
I’m going to add water tanks to my camping trailer. I was given a large dia pipe and thought it would work nicely. I went to buy end caps, and found out it is not std sch 40 or sch 80 pipe.
Pipe dimensions inside dia is 6.25 and outside dia is 6.875 with no other identifying marks. Can anyone identify this size pipe?
