Water pressure/ flow question

[duffer]

I too, think the plumbers cut corners by only installing a ¾" main line. Should have been 1", or better yet, run ½" home runs to all fixtures and utilize a manifold. Much better pressure, much better flow, and almost instant hot water at the faucets.

If you have access to the inbound lines, and can tie the hose bibs into the main line after the 1st regulator, I would agree with that post as well.

Another consideration: Some water faucets are designed to only flow a limited amount of water. Shower heads for example are designed to flow only 2.5 gallons per minute unless you remove the restrictor. I suspect that those hose faucets you have limit your water usage. Can you replace one with a ball valve so you have a straight thru 1/2" hole when it's on and see how that works out?
