I recently came across an installation that goes against all I was taught and how I interpret P3005.1, yet was passed by the local AHJ during a rough in. Here is a photo. Please give me your opinions.Attachment 21826Attachment 21827
Obviously, it is incorrect, but many times inspectors are "90 day wonders" or contractors who could not make it in the private sector. I have know inspectors who pass jobs without even getting out of their cars. One friend who used to work in St. Louis, said they called for a plumbing inspection for one building of two identical ones they were building. After the inspection, the inspector said it was the best installation he had seen in a long time. The only problem was he inspected the wrong building. The one that did not have ANY plumbing in it yet.
I sent the code official this photo without the notation, and he replied that he saw nothing wrong with this installation based on Table P3005.1. I then sent him the photos you see and he replied that it would be incorrect if the sanitary Tee was rotated 90 degrees. I replied that this would still be a prohibited use because by turning it 90 degrees it is now a horizontal to horizontal change of direction, which is STILL a prohibited use. He has not replied. I am not trying to be an ass here, I just want to know where he is coming from, so he can make me understand or admit he has been incorrect in his interpretation.
Right or wrong, he is ALWAYS the inspector, and if you don't want to be hassled on every job you do, leave him alone. Many inspectors are plumbers who could not make it in the private sector. When I was an apprentice, we had the inspector for a neighboring city working for us. I fired him because he didn't do things correctly. The apprentice at his new company was in school with me and he said all you had to do was get a few drinks into him and then ask him about apprentices and he would go on for hours about how he was a plumber for 25 years and some "green" apprentice thought he knew more than he did.
