Running 3/4" CPVC trunk for cold water. I'm connected to the line coming from the water meter and then I used 3/4" x 3/4" x 1/2" tees to each of my fixtures (shower, toilet, two faucets in vanity). After the fixtures, I turn down 90 degrees to my water heater. Are there any issues with this configuration as opposed to tee'ing off the 3/4" main and running individual 3/4" trunks for the water heater/fixtures? In other words, will it matter that the water heater is being supplied last in line instead of first? Will I have low hot water pressure if I'm running the cold water on say.. a vanity faucet or the toilet tank is filling?
