I am going to plumb the house I built soon. I will be running water lines to a on demand hot water heater, a steam generator, a shower, a tub and 2 sinks. My questions is it better to have one line for H and C that branches off via T connectors to all the above or use a manifold with a separate line running to each. Is there a difference in how each way would hold pressure in the line, meaning would one way keep more pressure in the line than the other way. Sorry for my lack of plumbing lingo I am a DIYer. Thanks for any help and or advice.
