Was wondering if anyone uses this? I am in a new building 2 years down the road with this system in place. My boss just invested 9 grand in tools for upkeep and new projects. Well now I have a new project coming up. I have read the manuals that come with it and it says the pipe needs to be reamed and deburred. Says there can't be any scratches on the pipe where it goes into the fitting so the o-ring can seal. I have soldered for 30+ years now and used regular plumbers sand cloth. But I don't know if those scratches are tolerable. Was wondering if something like a scotch-brite pad would work to clean the pipe? Thanks for your response.
