    No! As a rule we connect three fixtures on a 1/2" branch off a 3/4" main. Although you might wishto supply the cold water supply to the shower odff the 3/4" main to prevent temperature fluctuations when the toilet's flushed. Regards, Tom

    You would most likely be okay with three fixtures on a half inch line, but I would stick to two fixtures off half inch just to be safe.

    We run dedicated 1/2" lines off of 3/4" supply. This way, you have enough cold water when other fixture is in use. But practices wary depending on your location.
