In my small house I'm considering changing my whole system to PEX. Manifold system. A 3/4 inch pipe will run to the manifolds.
According to a PEX design guide pdf file I downloaded the other day
http://www.toolbase.org/PDF/DesignGuides/pex_designguide.pdf
3/8 inch pipes can be run from the manifolds to most fixtures. Can anybody verify that this will work out ok?
This is what it says according to the above guide, in section 1:75.
Minimum Sizes of Fixture Water Supply Lines
in Manifold Systems
Fixture - Minimum Pipe Size(in.)
Bathtubs and Whirlpool Tubs - 1/2
Tub and Shower - 1/2
Shower only (Single Head) - 3/8
Bathroom Lavatory - 3/8
Water Closet, Residential - 3/8
Water Closet, Commercial - 1/2
Kitchen Sink - 3/8
Laundry Washing Machine - 3/8
Utility Sink - 3/8
Bar Sink - 3/8
Urinal, Flush Tank - 3/8
Urinal, Flush Valve - 1/2
