I'm confused on which one I really need... I was able to remove the arrowhead vacuum breaker that i can't find anywhere locally....

We can help. Take a tape measure and measure the outside width of the threads on the spigot (with vacuum breaker removed). If it measures 1-1/16" or less, you need the SM01. If it measures 1-1/8 or a little over, you need the SM01.125. You can also just measure the inside threads of the adapter you removed. It will measure 1" for the SM01 or 1-1/8" for the SM01.125

Hello! i took calipers to the male threads coming off of my nibco classic pro faucet, and it's measuring at 1.24. i'm in the us, is sm-xxl right?

SM-XXL ~ Fits Watts NF8 EDP #0061854, NIBCO & Other Spigots Where the External Thread Diameter of Spigot Measures 1.3". Internal Diameter of Adapter is 1.25"

can the Spigot Master be screwed onto a installed back flow adapter

No. It's designed to be screwed onto the spigot once the Arrowhead back flow adapter is removed.

1 1/8 seems to be the thread size. Your 1.125 is just to big but according to your information, your 1.0 might be too small. Do I exchange for 1.0 siz

I thought the adaptor I ordered was the incorrect size. But then I carefully, very carefully, alligned it up and it screwed on perfectly.
