3/4' outdoor faucet???

djincnjFebruary 7, 2008

Hello All

I'm redoing some plumbing so I thought I run the new pipes for the outdoor faucets with 3/4" copper. Took awhile to find outdoor fauctes with a 3/4" connection but when I look closer it appears that the stem of the faucet is only 1/2" anyway. I'm looking at a Prier C-144 F inlet. http://www.prier.com/PDFFiles/c-144FreezelessHydrant.pdf

So the questions are:

1) Is there a true 3/4" Outside Faucet, Hydrant, Sillcock, Hose Bib or whatever you call it out there? Connection, stem, valve, ect... all 3/4"

2) Does it even make sense for me to run 3/4" to the faucet if its just gonna get reduced to 1/2" anyway?

Thanx for any insight

my local Lowe's has them, as well as the farm supply houses. we are an agricultural area, so many farms use the 3/4 for better flow rates when filling troughs and such.

Perhaps next time your over at Lowes you can take a peak at the manufacturers name and email it to me? I would greatly appreciate it.

Before you go searching the world over for this valve take a look inside, at the mechanics of it, you'll see that hose bibs force the h2o through a tiny hole. I'd wager that the size of the NPT will make little diffrence. What you might want to do is make your own with a full port ball valve and a hose adaptor.

You also might want to run a few hydodynamic calculations to figure out how much volume and pressure loss there will be by using the 1/2" valve. I don't have the formulas but one of the whizes here should. I'm going to guess that the losses will be tolerable.

Is there some reason that you need so much water at an outdoor hose bibb? Most garden hoses don't have a 3/4" inside diameter. If you're using a nozzle or a yard sprinkler, the flow of water is restricted even further. I can't think of a good reason to bother with this.
