just finished laying out the supply line, and all the drops are done on my DIY Uponor aquaplex total house replumb! just a matter of punching out all the connections and securing tubing etc. the fun stuff, all the grunting and groaning and four letter words are DONE. one question - i decided to add an extra hose bib where i have always wanted one, and thought it would be a good idea to do it in 3/4 for more volume, but i read in another site where the 1/2" and 3/4" hose bibbs have the same 1/4" or so inside outlet hole, so you are defeating the purpose. but couldn't i just drill that hole out to 3/8"?? or perhaps 5/16" first to make sure i don't sacrifice too much pressure??
