In Ohio, Cincinnati to be exact, it has always been accepted to put 5PSI of air on any DWV system. Including lower rough, upper rough, or additions. Now they are requiring a water test or putting the system on 1-3" water column vacuum.
I am not a fan of water testing, due to the fact there isn't always water available or sewer available, also on additions and remodels that are currently owner occupied, I would fear a plug blow out and flooding on existing property.
My question is, who is testing with vacuum, what gauge are you using. Are you using a vacuum pump or shop vac?
I attached a set up that one of my venders sent me. He doesn't know how they use it, but this is what they are making. Any thoughts??
