I'm on 2015 IPC... a few questions on Table E103.3(2) content:
- Hose bib isn't in the table. Use 2.5 for the first and 1.0 for each additional?
- Largish family front loader washing machine... use the 8.0lb private? That number seems small. What does a washer like this flow in GPM?
- OK to put Kitchen Sink, Dishwasher, and Prep sink on one 1/2" copper for Hot?
- My numbers seem to come back a fair bit lower when using a 'bathroom group', versus the individual fixtures. Do I have to add anything to 'bathroom group' for 2 sinks, 3/4 vs full bath, etc?
- Cold vs warm fixture units... due to DWH recirc and remodel conditions, my cold/hot water plumbing will not be symmetrical. Is the intent to use the total fixture units for sizing the main line and supply trunk, and use the hot and cold numbers individually to size branches?
