Re: Water leak under slab When you do the Pex, run 1/2" as a feed and then branch off 1/4" to the fixtures. Works great. |

1/4" to the fixtures is choking it down way too much IMO. |

Newtown, PA | It works very well for me. Besides, most fixtures are 1/4" fittings anyway, no? |

If it works for you fine. It doesn't work for me. There's a big difference in 1/4 (actually 1/8 id) for any distance and 3/8 (1/4 id) at the fixture itself.
Actually the above is for copper. I couldn't find any listing for 1/4 PEX. From their website:
PEX Tubing Technical Specifications and General Installation Recommendations

Newtown, PA | I keep thinking of everything as 1/4". Wherever I said 1/4 should be 3/8. |

That would only be true if you are talking about refrigeration tubing. Plumbing tubing is sized by ID as the chart you posted shows so 3/8" plumbing tubing has an ID of 3/8 but 3/8 refrigeration has an OD of 3/8". |
