I've tapped into my main vertical stack, but a second zoning issue is delaying much of my rennovations. This gives me time to consider how best to build my new dwv system to make for an easy testing by the inspector. I'm going to post some pictures of my proposed system, but here are my questions:
1) The inspector will need to "fill" the entire new dwv section with water and test it for leaks. Does this need to be ready when he arrives? Does he fill it?
2) My new bathroom is in the attic, with dwv run down a wall on the first floor, then across the basement and into a stack. Do I need to make arrangements to stop the dwv line just before it enters the stack so the system can be filled? I did cut into the stack, but stoppering it there would also impact the bathroom on the first floor.
3) If I stopper the whole stack, will I need to stopper each fixture individually?
4) What is the best way, given my proposed system, to accomodate the inspector?
I hear that you can install a speciall tee fitting with some kind of valve that allows you to cut off the flow, and then start it again so you can drain the water after the test. Where would I put it?
Here is a pic of the planned system. Once in the attic there will be a wet vented system with a double lav into a cross, then hooking up with and venting a tub, then a toilet right before the pipe turns vertical down the piping on the first floor in the picture.
Thanks for the advice.
