I'm just edging into the world of PEX water pipe.

I'm accustomed to the daisy-chain
copper pipe installations,
where the main feed might be 3/4",
local runs 1/2" and sink connections 3/8".

The PEX installations I see all have a "manifold",
then individual pipe runs to each faucet.

Is there a reeason for this ? *Can't be more efficient.
Or is it just "chancy" to daisy-chain PEX *??

It's simple - They sell more PEX this way...
