In this post you say it’s on the borderline of needing a 2” pipe.I don't know where you keep coming up with two inch this is another thing where you need to read.
The only thing the number of bedrooms determines, is the size of the water heater.
so from the border of 2” we skip 1.5”and arrive at 1.25” ? Is that what the book says ?Right on the border is right on the border, but he's on the 1-1/4"side.
If your book says that then I guess it must be true, that’s why their code book is garbage when it comes to residential sizing.In that pressure relm yes. There isn't a big enough difference between the two as far as the code is concerned.
My entire street has a 4” main @55 psi and you’re books trying to tell me this guy needs a 1.5” meter @45-50 psi at the meter.The pressure drop at the meter is why they upsize it. He's close to the minimum pressure. That's why it's goofy.
I don't have the book in front of me but I think 46 units is where it jumps to 2".
That’s right, and that’s why if a pipe is borderline needing to be 2”, a 1.25” wouldn’t do the job.,A 4" pipe is 4 times bigger than a 2" pipe. Pipe size is a function of the square. You can't just guess.
We don’t get along because you think 2” pipe is borderline but 1.25 is the correct size.Your mixing and matching. This is why we don't get along, you don't follow lines of logic. You just take left turns.
Ok here's the book. A 1"meter can do 38 units. A 1.5 can do 45. So add up the units again and see. I think i came up with like 40 I don't quite remember. I think i figured 6 each for his hydrants.
