New Drain Lines: Multiple Questions
Hello,
A couple questions about new drains on a bathroom renovation. 8' x 8' bathroom
1. The toilet is about 6' away from the 4" main that drops down and out of the house. Is it a good idea to run 4" over to the toilet, or is nothing gained by doing this because the toilet trap and flange are both 3"?
2. I have seen sweeping elbows that have a longer bend. Are these required for vertical elbows, or are the standard 90 degree elbows accepted? Directly below the toilet the line turns horizontal 6' and then drops down and out to the main. Can I use a standard 90 elbow below the toilet?
3. Should the shower and sink each be run directly to the 4" main that drops down and out of the house, or can they be run together and then to the 4" main?
4. The vent stack is located on the outside wall of the house directly above the 4" main that drops down and elbows out, leaving the house to the main. Therefore all fixtures will be before the vent. Is this OK?
Thanks,
Bill
