Greetings all! I had a backflow device (Zurn 975 XL) installed for an irrigation line. The line is 3/4" and the backflow device is 1". Is there any problems with this setup?
Would there be any advantage to it? I.E. better pressure or maybe he only had a 1" on hand?
I can't see any advantage, but it certainly won't be a problem with pressure or volume.
