 Water service line
Author: ChristopherA (MI)

I have a 1 inch water line coming into the house threw the wall. They broke it off by the meter in the wall. I went and purchased a 3/4 compression Union and a one-inch compression Union. The 3/4 is too small and the 1 inch is too big. Is there size that I'm missing?

if you have copper coming into the house the 1 inch sleeve may be for pipe size not tubing size.
copper pipe sleeve will have the letters CTS om it.. (copper tubing size)
