I believe you Terry. I apparently came over as not believing you in my post. As a matter of fact, I've been lurking your site for a couple of years now .. never psoted though .. and you obviously are the plumbing guru. Hence my lurking :-).
I do want to make certain that I understand that page though. Although it states that I only have 19 units available, and my total is 34, I should be okay as long as I only have less than 19 drawing water at once .. right? Or not? Also, what number of units would a sprinkler system account for?
Also .. if I use ALL 3/4" except immediately at each fixture (which is what I planned), that shouldn't be a problem either? Is there any harm with using ALL 3/4", even up to the fixture? I haven't had a chance to see if there are 3/4"-to-3/8" CPVC angle/straight valves (are there?)
Lastly .. the ID" of CPVC .. I can see that there is slightly less opening, for example with 3/4" CPVC vs Copper. Should I use 1" CPVC everywhere I would normally use 3/4"? The only problem I see there is clearance in areas where there is only 1" or so of clearance (between cabinets and concrete block walls).
Thanks for the site, Terry. There is truly a wealth of info here.
Confused1,
: That chart comes right out of the UPC plumbing code book.
: If you want to take advantage of the information that plumbers have to live by, fine.
: You could take the advice of the non-plumbers at the big box earning low dollars, but then, it is your house.
: You could plumb the whole house in 1/2 pipe if you want.
: It would never pass a plumbing inspection here though.
: These codes are meant to protect the homeowner.
: I've never believed in going with the least amount.
: I tend to size up to protect the homeowners.
: I do better than the chart allows for.
