I want to split a 3/4" cold water line before it enters the water softener. I want to run a dedicated hard water line to our icemaker, outside faucet and upstairs sink drinking faucet. My current 3/4" cpvc lines run about 15' after leaving the hot water heater before reducing to 1/2" cpvc lines for the remainder of the house.
My question is, does it matter when I reduce the 3/4" line after making the Split? Can Ido it immediately with a 3/4" x 3/4" x 1/2" "T" or should the reduction be located further away from the split?
