Re: Water leak under slab
said by owlyn: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.
It works very well for me. Besides, most fixtures are 1/4" fittings anyway, no?
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
said by Jack_in_VA: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".
