    Hi,

    I've tried to test my understanding of water supply, fixtures, and this handy sizing chart by doing a hypothetical replumb (copper) for my home. I'm hoping that more experienced folks can tell me how I did.

    Notes:

    • It's a small house, so I'm pretty sure everything falls well under the 80-foot threshold.
    • For simplicity, the diagram combines the laundry sink+washer as well as the kitchen sink+dishwasher.
    • The service line is 3/4".
    • The main cold water run to the water heater is already plumbed in 3/4" copper, which is why I kept that sizing even though I calculated the total units (20) to be slightly over the limit of 19. (Is this okay?)

    Thanks in advance for any feedback, corrections, suggestions, or additional reading...
