 | Plumbing inspector nightmare |

Question: As part of remodeling my kitchen I had to redo plumbing on the second floor bathroom that is just above the kitchen. I was pretty confident in my plumbing skills and knowledge as I did a bug plumbing project in my house before. I plumbed full basement bath including underslab plumbing, installed sewage ejector pump, stand pipe, utility sink. All work was inspected multiple times and except few issues that I had to correct everything was fine. Now a new inspector in my township came to check my new kitchen and upstairs plumbing. He rejected my work due to several problems to his view: 1. He said my house must have 1 3" vent and two 2" vents. I thought that vent size is determined by number of fixture units it vents. I have two 2" vents and that is more then adequate for my house with 2 1/2 bath. Can someone point me to the place in NPC where it states that house must have these number of vents. 2. He insisted toilet must have a wet vent instead of dry went that I put. Why does toilet must have wet vent and why dry vent is no good? 3. He insisted that rubber Fernco couplings that I used to connect new PVC DWV with old copper plumbing are prohibited despite I used them in my basement and previous inspector approved them .I also cannot understand if Fernco couplings are prohibited why any HD sells them?
Answer: You don't say where you are at. The local code can be different than the national code. In my state (MA) a homeowner can't do his own plumbing. I can't recite chapter and verse and I don't have a NPC book (builder not a plumber), but I can tell you what I think I know: The inspector has the authority to interpret the code as he sees fit. What the old inspector allowed is irrelevant. There is a new sheriff in town. When you change one thing it opens you up to changing everything to meet the code currently in force. Every house must have one 3" vent through the roof. Toilets are always vented down stream. You don't vent on the upstream side. You should check to see if there is a NPC on the net. We'll see if any plumbers come along and can recite chapter and verse. Have you thought about talking with a pro?
