I'm adding a second bathroom in our house. I've talked to the inspector to make sure my venting plans are correct, and now I'm ready to install the drains and supplies. I'm going to have the supply lines pressurized with the water supply so the inspector can see that there aren't any leaks. But I have a few questions on the drain side of plumbing:
1) I'm not planning on having the tile floor installed yet. Is it usually OK to have the toilet flange attached but not glued to the waste line for the rough inspection?
2) I'm going to have a Kerdi shower. I was planning on having the pre-sloped tray and drain installed and the drain glued to the waste line. How do you leak test the shower if the walls aren't up yet? I can't hang the sheetrock and Kerdi on the walls before getting rough framing inspection, and the rough framing inspector won't come out until after the rough plumbing inspection is done...I'm in a pickle!
3) This question ties into #2. When you leak test the shower, do you just plug the shower drain at the shower pan, or do you somehow plug the waste line and fill the whole waste line + shower pan with water?
Thanks in advance!
