Hello,
Looking for some help with a few general water supply pipe size questions.
I'm wondering what the impact on a supply system is of changes in pipe size. I am on Municipal supply fed by 1/2" copper from the main about 25 feet out through the slab. what happens if I run 3/4" as a main trunk off the water meter? Is there any reason to go from the smaller supply pipe size to larger?
Also wondering what the impact of the reductions in pipe size that are introduced with PEX 1/2" fittings which are considerably smaller than the ID of the 1/2" PEX pipe itself. Do these impact pressure and flow rate differently than the standard 1/2" copper fittings that go on the outside of the pipe instead of the inside with PEX?
Any thoughts or comments would be appreciated!!
Thanks
