I was about to install my water feeds with copper as usual but in conversations with several who have used PEX more recently they suggested going the PEX route for my new plumbing requirements, especially as I had some very tight areas to work with that may require several smaller joints.
In the attached drawing the two green lines represent the existing 3/4" copper lines coming from our basement (fed from a 42' dug well). The branch lines are the red and blue lines that will feed to the tub and the shower. All faucets have 1/2" connections. I know the ID of PEX is smaller than 1/2" copper so should I be running 3/4" PEX in my brach lines as far as I can then switch to 1/2" at the T for the tub and at the final wall connections for the shower unit (Grohe)?
What is the best connection I can make at (A) - left side - to go from the 3/4" copper to the PEX? Space is very tight in here with both copper lines and the 3" drain/vent stack being somewhat in the way of each other. There were three 5" heat ducts in this closet as well, one of which has been removed as it is no longer necessary in the new bathroom (there were three in the area we are converting, one of which will remain. zThe other is at the far right of the closet and is also in the way, thus the switch to PEX.
In this installation I show a 45º drop at the left end of the ABS (which will have a slope of 1/4" per foot)... The distance between the 45º and the Waste Y at the 3" horizontal Stack is less than 3'. Is this ok?
Thanks again for any assistance you can provide folks. The diagram is not to scale, but it shows the general idea... ie. the Tub drain is actually within 6' of one Vent stack and just under 7' from the other. The entire length of the room however is actually 17'.
