Are there any web resources/pages/sites out there that go in to the details of how different pipe diameters & elbow fittings (90/45 deg/T/elbows/etc.) effect water pressure? I've been searching & unable to find anything other than some things on gravity & how to angle pipes (well duh).
Or, someone here can briefly (if possible) explain?
I just recently converted all my cold-water plumming over to PEX from old galv pipes. My water pressure, probably not just doubled, but trippled (at least how I "architected" the pipes). So much so my old utility sink is having a hard time with it. But I did so based on some guessing work & it somehow all came together great.
For a few days, in one particular section, I ran about 5 feet of a 3/4 pipe from one fitting to another. Water pressure was great & such. Then I made some aesthetic modifications to better line things up & ended up cutting the pipe & setting up 2 x 90 degree angles (I made my own custom elbows out of 3 fittings instead of using the skinny PEX elbow). Anyway I have no idea.. maybe it's placebo effect or not, but I think the water pressure was even better than before. I guess a simple pressure guage would help but.. I don't have one yet.
So my questions are:
How do the different elbows effect water pressure?
(Logically it seems that the less elbows the better, but I don't think that's the case... seems like they can also be used to build pressure?)
How does a cut-over from 3/4 to 1/2 inch effect water pressure?
How does a cut-over from 3/4 to 1/2 inch (say 1 - 2 feet) and then back to 3/4 effect water pressure?
thanks again.
